Closed Issues in 2020-10



Open Issues Requiring Inclusion in Release Note:







Device specific New C/C++ project menu item


The quick link for RA project creation available on the File->New menu item has been removed. You can access the RA Project Generator via the New->C/C++ Project menu item.


Command "-break-insert " is still displayed in GDB console of non-active thread


In some situations, the enabling the "Restrict new breakpoint to active debug selection" toolbar button is not restricting the breakpoint to the debug selection. With 2 simultaneous simulator sessions it adds the breakpoint to both debug contexts.


User dictionary setup is not clear


When setting up a User Dictionary it is necessary to select "C/C++ spelling engine" in the Spelling preferences page before selecting the dictionary file


Run commands behaviour after a reset from the UI is not consistent


The GDB run commands which are setup on the debug configuration are not consistently applied. After the connection process they work correctly however on subsequent debugger reset operations the result is inconsistent.


Subversion Local Checkout - Database permanently locked


When using the Subversion Eclipse plugin (Subversive) along with an external Subversion client some problems can be caused. Please use either the internal or external client.


e2s hangs when debugging a project and this project was closed


e2 studio can hang when debugging a project and the project being debugged is closed. Please terminate the debugger before closing the Workbench.


'Launch in debug mode' button on the top left of the window will kill the current process forcedly.


When pressing the launch button on the launch bar when a debugger session is already in operation there is no warning message displayed. The current debugger session is terminated. If you wish to have more than one debugger session, please use the Debug menu rather than the launch bar.


Certificate approval screen can cause e2 studio to appear to lock


The certificate approval screen which appears during automatic smart manual installation can cause e2 studio to appear to lock. If this happens you can select another application, then going back to e2 studio to dismiss the dialog.


Cannot delete Hew project on e2s 6.0


HEW projects cannot be removed from the workspace after importing a HEW project. Since HEW project has some read-only/hidden files. If you want to delete the HEW project, please delete the following read-only/hidden files first. - xxx.rxc, xxx.rxa, xxx.rxg, xxx.hlk


Timing to show 'Unable to modify eventpoints' message is strange.


When the timer start/stop events are set in Editor view of RX, the message to notify the limit number may not be displayed.


Not possible to update e2 studio


If during the update process you see a message similar to: "Backup of file c:\renesas\e2studio\eclipse\e2studio.exe failed. File that was copied to backup could not be deleted: c:\renesas\e2studio\eclipse\e2studio.exe" Then this can be avoided by renaming the e2studio.exe executable after the check for updates process has started.


System Explorer launch breaking E2


On some systems you may encounter an error when launching the system explorer from the Project Explorer context menu. If using this causes e2 studio to freeze or context menus to stop displaying, you should terminate the e2 studio process.


Empty view on minimize and restore (Variables, Expression, IO Register, etc)


When minimizing a view such as Expressions, Registers or IO Registers and the restoring the view it can appear blank. If this happens repeat the operation and the view contents will be visible again.


Cursor hovering over the breakpoint Types causes e2 studio to crash


When using Ubuntu using Unity there is an issue which causes e2 studio to crash. When hovering over the breakpoint types the e2 studio application crashes. Caused by Ubuntu/Eclipse issue, see Eclipse Bug 419729. Workaround is given but cannot be added to product automatically.


Multi-byte chars should be denied as Build-Debug configuration name


Multi-byte characters can cause a compilation failure when used as a build configuration name in e2 studio. Therefore, multi-byte characters should NOT be applied to debug/build configuration names. Note: This issue affects both for configuration management dialog and the configuration creation dialog of Optimization Assistant.


RL78 on-chip debugging and reserved areas problem


In older versions of e2 studio the RL78 debugger would protect OCD memory areas for the E1 emulator. However, in some cases this would cause issues. This is no longer done and GCC projects will work well. If you are using IAR projects this may cause some problems for your debugging. A new GDB monitor command has been added to protect/overwrite memory. This will allow the same behavior as e2 studio 3.x. e.g. monitor protect_memory, fef00, 100, ff Any attempt to write to address 0xfef00 to 0xfefff will cause 0xff to be written instead. A warning message will be shown in the GDB server console window. This can be added to the initialization commands within the debug configuration for the RL78 E1 emulator.


The Module View of e2studio does not display any information when an executable which includes debug information was downloaded to the target.


The Module View of e2 studio does not display any information when an executable which includes debug information was downloaded to the target.


breakpoints cannot be unset within the editor when code is #ifdef out


Breakpoints cannot be unset on editor if the codes are out of #ifdef close. Those breakpoints can be removed in Breakpoints View.


Source Addresses: multiple debug contexts with same-named source file


When debugging files with the same name show source addresses even though it may not be correct for the file in question. The full file path is not considered just the filename and current debug context. This can lead to e2 studio showing addresses unnecessarily.


Exclude from upgrading the legacy projects with read-only files

ARM GCC Plugins

Project upgrade does not work well when the project files are read-only. It can result in errors which refer to an orphaned configuration. Instead please ensure files are writable before performing project upgrades.


Program does not step correctly for SOTB when library generator enabled

ARM GCC Plugins

Selecting an ARM toolchain that has libgen installed when creating a new RZ project, will cause the program to go to the default handler when stepping, after returning from function on SOTB board. There are 2 workarounds for this: 1. Use a toolchain that does not have libgen installed 2. Choose the options: Project-built, Optimized for Library Generator when creating the project and changing the selected options to Pre-built, Newlib after the project was created, by going to Settings->Library Generator.


Files not updated when changing the device

ARM GCC Plugins

When changing the device from a RZ/A1 and attempting to swap to a RZ/T1 the device migration is not successful. The source code is not migrated successfully, and the build fails. This is due to the different start-up code structure between these devices. In this case please create a new project and copy the required source to the newly created project.


[RZ] Project converter to fill FPU architecture option build fail

ARM GCC Plugins

Due to previous build plugin issues on conversion we add “.lib” to the build artifact output prefix in some conditions. Unfortunately, this can cause issues with some project types. If you experience an issue related to this, please remove the “.lib” and rebuild.


ARM DS AC6 toolchain definition doesn't specify binary parser

ARM LLVM Plugins

The ARM compiler 6 CDT managed build toolchain definition in DS plugins version 5.23.1 do not specify a "targetPlatform" and therefore does not specify a "binaryParser". This causes AC6 projects to not have a binary parser specified by default which means the .axf build artifact is not detected as a binary by CDT.


Linked source file build FAIL in path has special characters

CCRL Build plugin

Build project failed if there is a linked source which located in a path with some special characters such as '$','%'. This is a limitation of make file. Please avoid creating source file in folder with the special characters.


CCRX Build shows an error, Failed to access a temporary file during build of large projects

CCRX Build plugin

[CC-RX project] When building with the CC-RX toolchain at random the following message can be displayed 'Failed to access a temporary file' error is thrown by build process. This occurs more frequently on larger projects with complex include paths, or paths with linked resources. If this happens please repeat the build and it will work correctly.


[CC-RX] Some setting options is not updated correctly with user configuration and multiple configurations

CCRX Build plugin

[CC-RX project] If you specify options for multiple configurations using Multiple configurations, options may be specified for all configurations. (Ex: Endian option) In this case, specify options by each configuration.


Disassemble view is not updated when re-downloading during debugger connection.


When redownloading a download module after rebuilding it the disassembly and other views may display old data until manually refreshed.


Mouse over of variable crashes GDB server or makes e2 studio hang


With certain projects that use RTOS Integration in Debug View and expose Threads that contain only the 0xfffffffe frame in the Debug Tree View, mouse hovering over strings or macros defined as strings can cause the debug session to become unresponsive or GDB to crash.


[Breakpoint] Invalid breakpoint warning is lost after using Move To Line


After a move to line operation in the debugger the source window is updated, and breakpoint warning markers are removed from view.


Incremental build can break after renaming or copying a project


After renaming or copying a project incremental build might be broken & the project will perform a full build every time. If this occurs, then: 1. Open project proprieties & go to the "C/C++ Build" -> "Refresh Policy" 2. Delete the old name of project folder, then add the new project name.


Disassembly view does not always update on initial opening


In some cases, the disassembly view does not refresh correctly on suspend. When this problem happens refreshing the disassembly view does not fix the problem. To restore the functionality close and re-open the view.


Indexer setting not saved.


The setting 'Use a fixed build configuration' in the dialog, Properties->C/C++ General->Indexer is not saved when the user checks it. This can be caused by visiting the properties, modifying the indexer setting and then visiting settings. If you do not visit settings the option is stored correctly.


Disassembly view is empty after restart


After restart on occasion the disassembly window can be empty. Refreshing the window or stepping works around the problem.


[Multiple Configuration]: NullPointerException with custom configuration


NullPointerException is observed when adding a custom configuration and selecting the same configuration within the ‘Multiple Configuration…' selection at the same time. This issue only occurs if user has not applied after creating new config: https://bugs.eclipse.org/bugs/show_bug.cgi?id=352047


e2studio crashes when changing pin configuration

Code Generator plugin

When changing pin assignments for the RZ-T1 device on the "Pin Function" view in the "Device List View" window a crash may occur.


Loading e2studio7.7 project into e2studio 2020-04 and generated code, some code is different comparing with previous

Code Generator plugin

For CG RL78/D1Aafter loading project (e2studio project or AP3 project) which is saved on 32-bit environment in 64-bit environment, TAU0 channel1 input selection (refer to the red box in the figure below ) can’t be kept.


[CG] the value of "Clock Generator"/"Peripheral function used" is shown inconsistently on 2 views (Code Preview and Peripheral Functions)

Code Generator plugin

Even though a peripheral is used, the peripheral information is empty on Code Preview property. e.g.) Step1/ Create a project using Code generator Step2/ Open the project on Project Explorer Step3/ [Code Generator]/[Code Preview]/[Clock Generator] -> right click and choose [Property] Expected: The value of 'Peripheral function used' is 'Used'. Actual: The value of 'Peripheral function used' is empty.


Code Generator does not work with project located in SVN/Git repository

Code Generator plugin

Code Generator is missing when loading the project shared to SVN/Git repository.


Add support for -mno-allow-string-insns in code generator

Code Generator plugin

Code Generator for RX does not support '-mno-allow-string-insns' of GCC compiler option. Selecting '-mno-allow-string-insns' causes a buid error about 'smovf' instruction in 'r_cg_reset_program.asm'.


Code Generator not registered when installed in a separate folder

Code Generator plugin

When e2 studio is installed in multiple locations on the user’s machine and they are same version, the Code Generator does not work. [Workaround] Please execute "CGRegister.exe" under /plugins/com.renesas.cg_x.x.x.vxxxxxxx-xxxx/CodeGenerator/Tools


Function called from group interrupt hadler should have prototype

Code Generator plugin

Generated function called from group interrupt handler does not have prototype. W0520223 occurs when C99 is selected or -change_message=warning option is specified. In the following case, r_sci2_transmitend_interrupt and r_doc_dopcf_interrupt shoud be declared by prototype --------- void r_icu_group_bl0_interrupt(void) { if (ICU.GRPBL0.BIT.IS4 == 1U) { r_sci2_transmitend_interrupt(); } if (ICU.GRPBL0.BIT.IS29 == 1U) { r_doc_dopcf_interrupt(); }


Minimum and Maximum value are always 0

Coverage plugin

When using Data Coverage to collect variables information, Maximum and Minimum column are always zero, this issue occurs on all supported devices


Opening Measure Current Consumption View and then terminating debug session causes e2 studio to crash.

Current Consumption View

Opening Measuring Current Consumption (QE) view might cause e2 studio to not function properly anymore and a restart might be required.


Monitor point can't be set if NOP is not inserted at the top of the line.

Current Consumption View

When using monitor point insertion with CCRL 1.05 or CCRX 2.08 for the Current Consumption View, if nop is not inserted at the top address of the line because of the code generation or optimization, setting monitor point will fail. In this case, please insert NOP() in the source code manually.


[Debug Configurations] SWV/Core clock (MHz) value is disabled for SWD as default value

Debug Configuration

For J-Link Debugger Debug Configurations, selecting Interface Type SWD will enable Core clock (MHz) value input. However, when creating a new debug configuration, with the Interface Type SWD as default value, Core clock (MHz) value input is disabled. Please select SWD again to enable the SWV/Core clock field.


--fix-segments should be added (or not removed) with RA and E2/E2lite

Debug Configuration

When creating a project which uses the J-link ARM debugger a command line option --fix-segments flag is added to the additional GDB parameters on start-up. If you then switch to using the E2 emulator this parameter is removed. Please add this parameter back into the command line to ensure it continues to work well.


Automatic data flash erase on RL78 device during the debug session start via E1

Debug Configuration

Erase flash on start-up option on RL78 should be executed once. When e2studio connects successfully to RL78 target and erases the flash, this option should return to false, so that flashing is not done every time target is connected.


'Internal Flash Memory Overwrite' option for RX E1 needs the number limitation.

Debug Configuration

If more than 16 non-adjacent items are selected from the "Internal Flash Memory Overwrite" dialog, only the first items will be valid. Others will be discarded.


(RX) Selecting user boot mode always show the message.

Debug Configuration

When User boot mode is selected at the setting for Mode pin in CPU Operating Mode, the warning for USB boot program is displayed even if the device does not have USB boot program. Please click 'yes' if the device does not have USB boot program.


Rx, In flash write mode, debugger features should be disabled

Debug Configuration

When debugging with RX, if the settings are in flash write mode, the debugger features are not available. If the ID code is changed or the communication I/F is FINE, reading memory will fail after download finished. Please disconnect from emulator and pull USB cable out in this case.


More than 4 'Internal Flash Memory Overwrite' blocks are allowed

Debug Configuration

When setting the 'Internal Flash Memory Overwrite' debug option, it is possible to exceed the maximum number of non-continuous memory blocks supported. No warning is given if this limit is exceeded. When setting this option ensure the limit (16 for RX devices) is not exceeded.


Cannot connect to RZ if "Image Only" is selected as Load Image

Debug Configuration ADAS

When writing the PC register, GDB needs to know in what mode it is ARM or Thumb. Usually this is obtained from the symbol information but since the symbols are not loaded ("image only") GDB tries to obtain this from the cpsr value from current frame. However, in this case there is no frame information which causes an error. There is a workaround, we can tell GDB what mode we are running so it doesn't try to read the cpsr register: set arm fallback-mode (arm|thumb|auto) GDB uses the symbol table, when available, to determine whether instructions are ARM or Thumb. This command controls GDB’s default behavior when the symbol table is not available. The default is ‘auto’, which causes GDB to use the current execution mode (from the T bit in the CPSR register). This can be added to the GDB [Startup]/[Initialization Commands] section in the debug configuration


RH850 debug configuration needs to support blank flash memory fill option.

Debug Configuration RH850

When viewing flash memory in the Memory View, it can be confusing as the values for this memory type can be random for unwritten blank flash memory regions. This can then result in many false postives for memory changes, resulting in more memory changes than expected. (red text) To fix this the debugger supports detection and filling of blank addresses areas with a user specified hex byte value. There is currently no user interface support for this feature. So you need to add the following command parameters to the additional commands section of the debug configuration. The GDB commandline option is: -uBlankFlaskFill= BB with the blank fill value being 0xBB. Specifying this value enables the feature, by default it is off.


GUI can't be updated when changing "Verify On Writing To Memory" option

Debug Configuration RX

In Debug Configuration settings, if the value of the RX device's "Verify On Writing To Memory" option is changed, the change cannot be updated when opening the 'Debug Configuration settings' again


Support multicore for RVDC view

Debug Console plugin

Reneas Virtual Debug Console view have just supported multi-sessions. In case the session has multi-core, it cannot realize, then it will show data from cores into single view. The data will be messy.


RVDC does NOT show data when multicore devices such as RZ/T

Debug Console plugin

When creating Launch Group with 2 different RZ/T projects which have 2 different cores. The second project can show data on Renesas Virtual Debug Console but the first project cannot.


E2 Studio "Console" view - "Renesas Debug Virtual Console" issues

Debug Console plugin

Renesas Debug Virtual Console's pin status will not be restored for next opening e2 studio. Please active and pin it manually before debugging to avoid losing data.


[RX] SETPSW instructions are not disassembled in debugger


When debugging with RX devices, the SETPSW instructions are not disassembled by the debugger.


Breakpoint does not relocate after download


When there is an active debug and a relocated breakpoint, when the download action is executed the relocated breakpoint marker is not shown correctly; it is shown on the requested line, not the relocated line as expected.


Debugger crashed at variable array declared in stack frame


Under some circumstances, evaluating a variable length array might show wrong results or even cause GDB to crash. This is known to happen when we try to evaluate a variable length array and the instructions that write the information regarding that array have not yet been executed. This is a GCC bug and can be found at https://gcc.gnu.org/bugzilla/show_bug.cgi?id=93380. One way to work around this problem would be to use a fixed size array. Another workaround can be close the Variables View and open it again/ evaluate the variable length array once the code that initialises the memory has been executed.


Debug execution status is incorrectly reported after Restart under certain conditions


When the debug Restart button is clicked, if it is not possible for the system to insert a breakpoint on main, the program will fail to load correctly, and the Debug view will incorrectly report the program as running. Workaround: make sure there is a free breakpoint available (the maximum number of breakpoints is not already inserted) before clicking Restart.


Connection will fail if max+1 breakpoints are set.


If setting breakpoint is failed, the breakpoint is marked as exclamation in the editor view (or marked as un-checked in breakpoint view). In this case, if debugger is disconnected and re-connected, connection will fail. To avoid this, please remove the failed breakpoints before connection. And also, this will happen if "Set breakpoint at" is checked in the debug configuration, when the flash programming is disabled. In this case, please set the check OFF before connection.


Cannot launch debug session when breakpoint cannot be set


If GDB is unable to set a breakpoint during the launch, then the whole launch will be aborted. Removing the breakpoint(s) will allow the launch to complete successfully.


Investigation into Progress Information dialog repeatedly pops up after clicking relocated breakpoint

Debugging RA



RA6M4 - J-Link ARM fails to read clock frequency. Reset required to continue.

Debugging RA

When debugging with the RA6M4 in SSD mode there can be problems with the Run-Break performance measurement feature. After program execution reaches the first breakpoint the target then needs a manual reset to continue. The workaround for this feature is to disable run-break performance monitoring in the Debug configuration or use a manually defined frequency. e.g. 200mhz for RA6M4.


[RA6M4] NSECSD debugging fails if non-secure region is not pre-downloaded with non-secure program in SSD state

Debugging RA

In case of using RA devices which support ARM TrustZone, a temporary non-secure test program must be downloaded into the non-secure region in SSD state before transitioning the state to NSECSD state. If the non-secure region is not pre-loaded with a non-secure program, non-secure project debugging in NSECSD state will fail.


Watch point doesn't work on ARM V8M Devices(RA2A1,PEAKS,STAR) with J-Link

Debugging RA

When using the J-Link debugger for ARM V8M devices (Synergy S1JA,RA2A1,.etc) When setting Watch points, if the [Compare Setting] option is not being used then please set the [Data Access Setting]/[Size] to "Byte". Other settings will cause the break event to be missed or unexpected break events to happen.


Cannot find binaries when debugging a project compiled with AC6

Debugging RA

When using the Flexible Software Pack (FSP) and the RA family with the AC6 compiler when trying to debug you may see the error: No binaries found To overcome this issue please update the debug configuration as follows: Debug Configuration ->Renesas GDB Hardware Debugging -> Main -> C/C++ Applications -> Paste path to binary file (*.axf).


Debug Tools Settings for RA Debugger Connection does not render correctly on Ubuntu 20.04.1 LTS

Debugging RA Linux

When using e2 studio on Ubuntu 20.04 LTS the debug configuration may on occasion not render correctly. If this happens please re-size the dialog and then it will redraw and render correctly.


IAR RH850 setting breakpoints doesn't work

Debugging RH850

If you are debugging RH850 with the E2 emulator with an IAR project you must ensure that the IAR RH850 plugins are also installed. Otherwise it is not possible to set breakpoints.


Eventpoints of RH850 are not restored correctly

Debugging RH850

RH850 event points are not restored correctly on subsequent debug sessions. You will need to re-set the event points on subsequent debug launches.


[RL78] Strange behavior with hardware breakpoint

Debugging RL

In case of using RL78, hardware breakpoint is realized by execution address after PC. This will cause several issues: - Temporary hardware breakpoint will not be removed after the breakpoint is hit. Therefore, the breakpoint will always hit. Please remove the temporary breakpiont manually after the breakpoint hits. - In case of RL78/G10 (or RL78 devices which flash programming is disabled), software breakpoint is not supported. Therefore, temporary hardware breakpoint will be used for the cases: * Stepping over * Stepping return * Run to line * "Set breakpoint at" is specified in the debug configuration * etc When using these operation, if breakpoints are used in the debugging program, the operation will fail. Please release 1 or more breakpoint before the operation. And please invoke GDB command 'delete breakpoints' in Debugger Console view to remove the breakpoint after the program is suspended by "Set breakpoint at main". If the breakpoint is kept as it is, it will always hit and the next operation such as stepping return or stepping over may fail because no breakpoints can be used for the operation.


Cannot connect to EZ emulator when another debugger is connected.

Debugging RL

When using EZ emulator with RL78, if another emulator like E1 is connected to PC, connection to EZ emulator will fail. Please don't connect another when using EZ emulator.


Fail safe break message not clear on RL78 IECUBE

Debugging RL

When the failsafe break is configured to "Stop on read from uninitialized RAM" on the RL78 IECUBE the break occurs but the cause is not clear.


Error Dialog is shown when disconnected.

Debugging RX

When hitting Disconnect on a running debug session (with breakpoints in use) the debugger will error and fail to disconnect Workaround: Only click Disconnect when the session is paused (the Disconnect operation will return the device to the running state automatically)


Breakpoint filter is not restored when reconnecting debugger

Debugging RX

If you perform Disconnect-> Connect operation on the debugger, the Breakpoint Filter setting will not be restored correctly. In the above operation, check the Breakpoint Filter and reset it manually.


Trace does not show label for RZ/T1-QSPI project

Debugging RZ

In some cases when using the RZ/T1 device with the QSPI project, trace results do not appear to be correct. In some cases, labels are not shown correctly and instead we get multiple instances of the address 0xFFFFFF0.


RZ/A serial launch with Linux target doesn't show console output from target

Debugging RZ Linux

With ethernet based connections for Linux target debugging, e2 studio starts GDB server and captures output of the process. With Linux target, serial connection GDB server is started but the console output is not captured.


RZ/A serial COM port doesn't work if port number is greater than 9

Debugging RZ Linux

RZ/A serial COM port does not work if the port number is greater than 9. If Windows assign device USB COM port to 10 or above, then gdb can't find the port. gdb shows, "No such file or directory"


ITM Live Trace does not work after Trace (The Trace View) is enabled (even if it is disabled)

Debugging Synergy

The ITM Live Trace view does not work after the Trace is enabled in the standard Trace Window. Even if it is subsequently disabled. Terminating and re-starting the debug session with trace disabled in the trace window will then re-enable ITM Live Trace output.


Enabling BSD sockets in ThreadX source code breaks RTOS Resources View

Debugging Synergy

When using the Synergy editor if you enable the BSD sockets in the ThreadX source code updates to the RTOS resources view and e2 studio debug view will no longer work correctly.


Coresight SWV Clock setup needs improvement

Debugging Synergy

On Synergy devices the default "Core Clock" value for SWV usage should be set to the same as the system clock (in Mhz). For S7 devices (where the trace clock is halved) this should be set at half the system clock.


On RL78 simulator, time measurement when the device is in standby mode does not work correctly

Device Support RL78

On RL78 simulator, when the program is on standby (in halt, stop, or snooze mode for an RL78 device), the run-break time is not correctly measured in the following cases. • Suspended a program in standby mode. • A program is run following standby mode (run after suspended).


"Migration needed" dialog appear when reopening Debug configuration dialog

Device Support RX

Sometimes, when changing Debug Hardware in Debug Configuration to Segger JLink, "Migration needed" dialog will be appeared unexpectedly. Please close this dialog and other action will work normally.


[FFW] Current consumption issues for RX100 and RX200

Device Support RX

1. Only the "USER I/F" is supported for power supply interface. Cannot be used with "E2 expansion I/F". 2. When monitor point is set, current consumption may be measured for a certain period even after user program stops.


RZ/G debugger Renesas Device Support

Device Support RZ

When opening Renesas Device Support tab of e2 studio Installation Details dialog, it is described that J-Link ARM is supported for RZ/G. However, JTAG debug for RZ/G is not supported. Only TCF connection debug for Linux application is supported.


RA E2 Emulator: Data-flash is not erased Even if "Erase on-chip data flash before download" = Yes

E2 Emulator

When using the E2 emulator with the RA device family the data flash is not erased even if "Erase on-chip data flash before download" = Yes. If the download module is not located in the data flash area the data flash is not erased.


E2 Emulator: On-chip Data flash was always erased even if "Erase on-chip data flash before download" = No

E2 Emulator

In case of using RA devices with E2 or E2 Lite emulator, the option "Erase on-chip data flash before download" will not work if the download data for data flash area is not included.


Console Find fails to report items which are indeed present

Eclipse Platform

Sometimes attempting to find some text in the Console view, using the Find/Replace dialog, fails. The workaround is to select in the Console you wish to find in, then attempt the find.


e2Studio Installer Fails with Spaces in User Name (Windows)

Eclipse Platform

The e2 studio installer can fail when installing to machines where the user name has spaces included in the name. If you can login with another user name such as “Administrator” then this problem can be avoided.


Eventpoint view cannot count hardware breakpoint at main

Eventpoints plugin

When using the RE device the maximum number of breakpoints that can be set does not count the automatic breakpoint set at main. This can then cause a connection failure as this breakpoint cannot be set and the sequence fails. Removing one user breakpoint will allow the connection to complete successfully.


Should not count number of HW Breakpoints as eventpoints when they do not share HW resource

Eventpoints plugin

If debugging ARM device with E2 emulator, when setting hardware breakpoints they will be counted as eventpoints on Eventpoints view. Please ignore them from the number of eventpoints.


Eventpoint is not unchecked automatically when setup fails.

Eventpoints plugin

When using J-link with RA, when setting a start tracepoint event it appears that the eventpoint is not set. A warning icon is displayed. However, the event point still works as expected.


A warning dialog appears when re-debug project (eventpoint).

Eventpoints plugin

When connecting to debugger, Warning dialog for Eventpoint setting sometimes appears and the following message is shown. "Some eventpoints were disabled before being applied. This may have been caused by multiple eventpoints with trigger counts or address ranges". In this case, please disconnect debugger and connect debugger again. Or, please enable each event points manually.


Get correct number of HW breakpoints and eventpoints

Eventpoints plugin

The event count on Eventpoint View shows the total event count including hardware break points which are set on source view as line break points. Events which can be set in Eventpoint view may be less than displayed.


Data Access Event Break compare value always converted to hex

Eventpoints plugin

When adding a new Data Access eventpoint, the Compare value (on the Data Access Settings tab) is always converted to hex and subsequently displayed in hex even if the value entered does not include an 0x prefix.


Eventpoints disabled when e2 studio first opened.

Eventpoints plugin

The enable state of eventpoints for any debug configuration is not restored when the debug configuration is launched for the first time after e2 studio is started. In subsequent launches the eventpoints are enabled/disabled appropriately.


The RX simulator does not allow trigger count on data access events.

Eventpoints plugin

The trigger count for data access event for RX simulator will be ignored.


Exposed secure function for TrustZone project doesn't have debugging information.

FSP Code Generation & Builder

When debugging a secure and non-secure project - the Non-secure callable functions do not have debug information. This means you cannot set breakpoints in the secure function.


e2 studio ThreadX control symbol addresses update when loading multiple elf files.


When using Synergy with ThreadX debugging problems can be caused when using multiple load modules. Subsequent changes to the ThreadX table are not recognised by the debugger and this can cause incorrect thread data to be displayed. To avoid this ensure the ThreadX table data is within the first load module downloaded by e2 studio. If this does not remedy the issue you can disable the Debug view ThreadX debugging within the debug configuration.


GDB Simulator Debugging (RH850) fails


The simulator provided in the RH850 GDB will not 100% operate as a functional simulator for RH850. The implementation is not complete.


Change eventpoint setting when program is suspended may change the content of trace data

GDB server

In case of using trace feature with RX200 or RX100 series, if event setting is changed before the trace information is displayed, the incorrect contents might be displayed. Please do not change the event setting before displaying trace information.


Semihosting - printf causes subsequent file operations to fail

GDB server

When using semihosting, having a printf command before file io operations causes them to fail. Scenario best explained through sample code. Create a synergy Blinky project in hal_entry.c at the top of the file include the following line: #include "stdio.h" //inside void hal_entry(void) try the following samle code: ///------------------------SAMPLE CODE-------------------------- initialise_monitor_handles(); printf("Hello\n"); FILE * pFile; char c; pFile=fopen("c:\\alphabet.txt","wt"); for (c = 'A' ; c <= 'Z' ; c++) { putc (c , pFile); } fclose (pFile); //-----------------------END SAMPLE CODE--------------------- // Before fix, the Renesas Debug Virtual Console has the following output Hello // There was no file c:\\alphabet.txt //After fix the Renesas Debug Virtual Console has the following output Hello // There should also be a file c:\\alphabet.txt created, with the following output: ABCDEFGHIJKLMNOPQRSTUVWXYZ


[BREAKPOINT] (RL78) Behaviour in the case of the error by Add Watchpoint.

GDB server

When sub menu "Add Watchpoint" is performed from a Memory view, it seems to have been registered correctly in the Breakpoints view even if there is an error condition. An error occurs by "Add Watchpoint", when the maximum number of events was exceeded, or when a ROM area is specified.


Profile shows wrong data for RH850

GDB Server RH850

When measuring Profile with RH850, wrong measurement result may be displayed. Profile measures based on Trace data, but there is no problem with Trace data.


rh850 BPC events do not count in the status area of the eventpoints view

GDB Server RH850

The counter of the event points in Eventpoint view will not be counted correctly.


Trace record event for READ access with compared data acquires information which does not match it.

GDB Server RH850

To use the data access events as trace start, trace stop or trace record for RH850 with E1 emulator, please do not use the "Compare Settings" condition for the event.


The value on the memory view is not updated with RL78/G11

GDB server RL78

In the memory view, when displaying the IO area and the memory area near the address adjacent to the IO area, FF data may be displayed depending on the display area. Applicable devices are all devices of RL78 and RH850. The workaround is to display in Expressions view.


[RL78/G10 with EZ] program doesn't suspend at reset vector

GDB server RL78

There is a known issue when debugging RL78/G10 with the EZ emulator. In some condition the program doesn't suspend at reset vector.


Setting RL78 register fails

GDB server RL78

When using RL78 the HL register value cannot be modified in some circumstances. This will only occur when bank 0 is not selected. Changing HL value only ever causes Bank 0 HL to change. View will always show current bank value. Values not in bank 0 can still be changed by accessing bank registers directly.


BeforePC events on IECube temporarily hardcoded limit of 4

GDB server RL78

Before PC events on IECube temporarily hard coded limit of 4.


Coverage feature of E20 can't show the data over banks.

GDB server RX

E20 emulator has the coverage 4 * 4MB blocks for RXv2 core devices. This block is aligned with 4MB boundary. If the program executed from the block to the next block without branch, the coverage from the top of next block to the first branch will not be recorded.


Connection Exception with RX64M GR-KAEDE Board using last known connection

GDB server RX

Project based variables in the debug configuration are not evaluated correctly at launch and the launch then fails. This is caused by the project based variables being evaluated on the context of the active project not the specified project in the debug configuration. Using variables with a workspace context work correctly.


Execution time for the last function may not be displayed in Profile View.

GDB server RX

In Profile view, execution time for each function is calculated for the function which is returned out. If the execution stopped at the middle of the function, execution time of the function may not be added.


Memory View for RX Little Endian shows IO endian reversed

GDB server RX

RX targets and IO registers greater than 1 byte. e.g. winA 0x88028 winB 0x8802a View register in both IO view and register view. Value in memory view is reversed. This is because the IO, (like all RX memory for little endian targets is reversed).


[RX] The debugger works same as 'Equals' even if I select 'Not Equals' in 'Comparison:' of 'Data Access Settings'. (only when 0x0 is specified to Mask Value)

GDB server RX

When a data access event for RX is set with the data mask value as 0, the comparison will be treated as "Equals" and the data mask value will be treated as 0xFFFFFFFF.


[BREAKPOINT ISSUE]: Execution Address Eventpoints with trigger count do not work with Breakpoints on Segger RX

GDB server RX

Execution Address Eventpoints with trigger count do not work with Breakpoints on Segger RX. Setting an execution address eventpoint with a trigger count on Segger JLink RX62N is not possible if any breakpoints exist, including the default at main. If an execution address eventpoint with a trigger count is set with a breakpoint both the eventpoint & the breakpoint do not function. Multiple breakpoints are set then only 1 does not work. Additional eventpoints function as normal.

when using the RZ/A1 and debugging using Eventpoints. Event break using the "Compare settings" feature does not work correctly. The program will always stop regardless of the compare settings.


RZ/T1 Reload doesn't work on RAM_BOOT project

GDB Server RZ

For RAM based RZ-T1 projects a redownload of code will trigger a reset that erases the RAM making further debugger operation impossible. The workaround is to instead disconnect and then reconnect.


e2 studio crash relating to threads shown in debugger view

GDB Server Synergy

In some circumstances, when operating with many ThreadX threads that are also using large structures it can cause problems when refreshing the debug view after the debugger is suspended. In some cases, the e2 studio application may appear to freeze and become unresponsive. if this is happening then the best method is to go to the Debug Configuration->Debug Tool Settings and switch off the RTOS Integration in the Debug View.


Not possible to ALeRASE ID to erase device when ID byte is programmed under e2studio

GDB Server Synergy

Currently the use of the special ALeRASE ID code unlock does not work correctly with e2studio. The device will remain locked. The workaround is to use the ALeRASE code in the RFP tool instead.


[Trace view] The Filter + Find feature seems not work correctly with Synergy project

GDB Server Synergy

Trace find and filter functionality is currently not supported for ARM-based devices



GDB Server Synergy

On Synergy S3-based devices the trace can sometimes fail with 0 records.


BRAVO project cannot execute Pre-build steps/Post-build steps with executing Build.

RL78 Plug-in Fails in Debug Mode Unless Code Generator is added to Project

IAR plugins

When creating a IAR RL78 project (v3.10.1) for the E1 emulator and the RL78 G14 device the debugger connection does not work correctly. As a workaround adding the code generator to the project and setting the debugger to "Used" will configure the start-up code and project to be debugged successfully. The IAR ILINK command file provides #define __RESERVE_OCD_ROM to allocate ROM area for debugging, however adding this into the settings still does not allow a successful connection.


Synergy IAR static lib project cannot be converted to exe

IAR plugins

When generating a Synergy static library project using the IAR toolchain it is not possible to change the build artifact to Executable (IAR). e2 studio gives the impression that the operation was successful however when building no object files are generated.


[IAR][RL78] Linker extra options were not imported

IAR plugins

In some cases the IAR project importer does not perfectly import all set build options. One example is the -HFF command line option that can be specified in the command line options text box for the linker.

To avoid this, you either need to re-select RA on the Device Family selection page or uncheck and check again "Renesas FSP Smart Configuration Core" on the Features page


e2 studio online update fails if any Language Packs are installed


Updating e2 studio to 2020-10 from 2020-07 or 2020-04 using the built-in update system will prevent e2 studio from starting correctly if you have the Japanese or Chinese language packs installed. To fix an e2 studio in this state you need to run e2 studio on the command line using the "-clean" option once the update has been performed. (e.g. "e2studio.exe -clean") As a result of this the 2020-10 update will not be offered to 2020-07 users automatically. To update either use the installer to perform an upgrade or add "http://www2.renesas.eu/_custom/software/ree_eclipse/2020/2020-10/" as an update site within e2 studio then perform "Check for updates..."


QE Tools removed with Update from 7.6 to 7.7


When updating e2 studio versions using an installer any installed QE tools are removed and then must be reinstalled. To preserve QE tools during an update use the "Check for Updates" function in the "Help" menu to perform an online update.

If the Windows profile user name has a space within it, such as "John Smith" it can cause problems when creating projects. A RZ project cannot be created in case user folder has white space. An error dialog will be displayed. Please change the workspace to an area without a space.


Import legacy project with Japanese build mode name configuration

Project Generation Core

When importing user-created configurations with Japanese (multi-byte coded) names after importing into e2 studio the configuration names are reverted to English. When this problem occurs the options set in the configuration are lost. Therefore, it is recommended not to use multi-byte characters for build configurations. The workaround would be to rename the configuration following import and then manually reset the options as they were before import.


"Rename & Import Existing C/C++ Project into Workspace" option allows the use of illegal characters in the new project name

CMSIS Pack Import feature does not work for RA on Linux

RA Configurator

The CMSIS Pack Import feature does not work for RA on Linux Host OS. A workaround for this issue is to copy the required CMSIS pack directly into the relevant Renesas family's internal pack folder. For example, with Renesas RA it can be placed into "/internal/projectgen/ra/packs" and will be detected upon (re)starting e2 studio.


add driver warning is not removed after adding the driver

RA Configurator

When using RA and creating a RA6M4 project, warnings are shown in the problems view. These problems relate to the pin configuration for the device. These state "X requires a software driver. Please add a new driver in the Stacks page". However, even after adding the new driver that uses a pin the warning remains present in the user interface.


Heap configuration settings not getting updated for AC6 compiler

RA Configurator

For a Renesas RA FSP project in e2 studio 7.6, setting the heap size property in the Configuration Editor for an RA project does not pass this modified heap value to the linker script options (AC 6.12). One workaround for this issue is for the user to manually edit the linker file (e.g. .scat) and set the heap size value in there as well.


Deleting debug folder causes TZ projects to fail

RA TrustZone

When debugging a RA TrustZone project, if you delete the Debug folder from a Non-Secure project it causes a build failure when referencing NSC guard functions. This can be corrected by a Clean project operation.


"script" folder is not a source folder

Renesas Synergy

When using the Synergy device family with SSP the "script" folder, which contains the linker script files is not configured as a source folder. This means that this file when modified does not cause a rebuild of the project. Please clean your project and then rebuild it to avoid problems.

Renesas Synergy

Please note that the S1JA device is only supported by GCC in SSP 1.6 or later. Earlier than that it was supported by the IAR toolchain only.


IAR synergy ELF files don't have a .text section

Renesas Synergy

When loading Symbols from multiple .elf files compiled using the IAR toolchain, the user will need to add ".text" before place in FLASH_region command inside the .icf Script. e.g. {code} ".text": place in FLASH_region { block LOCK_LOOKUP, ro, ro section .rodata, block QSPI_NON_RETENTIVE_INIT_BLOCK, block RAM_INIT_CODE, block USB_DEV_DESC_BLK }; {code}


Rename and Import of 6.2 project into 7.x, then upgrade SSP, selects different pin configuration

Renesas Synergy

In the Synergy Configuration editor, when upgrading SSP version, or changing Board, where the selected device is not the default device for the selected Board, an incorrect Pin Configuration may be selected on the Pins tab. If upgrading SSP version or changing Board when in the Configuration editor, please check that the required Pin Configuration is still selected on the Pins tab. If not, re-select the required Pin Configuration from the drop-list.


The TB_S3A6 & TB_S5D5 are breakdown with IAR building problem

Renesas Synergy

When converting from a project building with the IAR v7.x builder to using the IAR v8.x builder problems can occur. It has been noted that in some situations the linker file points to an incorrect linker file. e.g. After importing the project, the Linker configuration file is set to "${workspace_loc:/${ProjName}/script/S5D5. When switching the tool chain to 8.x the linker configuration file is set to ${sdkLocation}/config/generic.icf Changing the linker file path back to the originally selected one should resolve this build error.

Creating RZ/G project lets you continue with no toolchain selected


Depending on the selected RZ/G device it is possible to create a project without the required toolchain. The RZ/G1 family uses the 32-bit Linaro and the RZ/G2 should use the 64-bit Linaro distribution. It also permits you to select a wrong combination of toolchain and device. If you select a project that needs one of these and it is not installed the project generator will let you proceed. This will mean your project will not build. Please download the correct toolchain and register it to fix this problem.

When doing filter with big Trace Capacity (Trace Capacity > 1M), the filter job does not work, and you may see a TimeOutException. After that, if you do scroll Trace View, e2 studio will crash. Workaround: If the see TimeOutExecption when doing filter, wait about some minutes (~10 minutes) for the filter job finishes, then change the displayed mode (enable or disable one of BUS/DIS/SRC modes), filter result will be displayed and you can scroll Trace view as usual.


Real-time update does not work when debugging multiple projects while one is suspended

Visual Expressions plugin

When debugging more than one project simultaneously Realtime Update will not work when any project is suspended.


JLink remote IP connection needs IP address and port parameter in Debug Configurations

Debug Configuration

It is now possible to configure JLink to select a remote IP name or address. However currently the user interface does not support this feature. It can be supported by adding extra commands in the debug configuration. Under the Jlink section in the Debug Connection settings you can select USB or IP. If IP is selected, then you will need to specify an IP address/name and optionally a port number. GDB Server expects the command line parameter (examples): -uSelect= IP= -uSelect= IP=localhost:0 -uSelect= IP=jlink.segger.com   













Fixed Issues Requiring Inclusion in Release Note:








Japanese Characters do not display in the editor or console

Eclipse Platform

In some cases, non-ASCII (e.g. Japanese or Chinese) characters may not display properly in the editor or console views when mixed with ASCII characters on the same line. As a workaround change the "Text Font" in "Preferences -> General -> Appearance -> Colors and Fonts" to "MS Gothic" where it is available. This only effect rendering and not the file contents. A fix will be provided in the next e² studio release.


All source files are "No target file" when exporting a project as common project file

CubeSuite+ importer/exporter

Fixed bug if top folder is specified as source location and each source folder is not specified as one, some source files are filled in node in common file when exporting the project.

[CG]_Cannot add Code Generator to supported IAR project.

Code Generator plugin

It is not currently possible to add the code generator to a RX IAR project which is using the version 4.x. An error will be displayed with the error message "The selected project is not supported by Code Generator!" Note: This issue does not occur with IAR Toolchain for RX (3.x).


Cannot start e2studio image due to Code Generator .Net Framework Exception

Code Generator plugin

This issue can occur when using multiple versions of e2 studio of the same version. If e2 studio is installed in one location and then another installation of the same version is installed on the same machine, then the older installation is deleted or moved. The code generator component which is registered in the registry no longer exists. This will cause problems with the other e2 studio installation as it will try and use the code generator component as defined in the registry. To avoid this run the tools within the Code Generator plugin directory of the e2 studio you are trying to launch. e.g. C:\Renesas\e2_studio\eclipse\plugins\com.renesas.cg_2.11.0.v20180601-1047\CodeGenerator\Tools\ First run "Unregister COM.bat" and then run "register COM.bat".
