Debugging application project does not stop at main and program does not run. selecting reset/restart button runs the program.

Debugging Synergy

When debugging of project in some situation the project may halt at the reset handler and then when resuming the program does not stop at main. The debugger console then shows the following message:

Program received signal SIGINT, Interrupt.

0x00014f74 in NMI_Handler () at ../synergy/ssp/src/bsp/mcu/s5d9/bsp_group_irq.c:197 197 if (1 == R_ICU->NMISR_b.NMIST)

If you experience such a problem, then you can set the "Reset before run" option on the debug configuration.


Developer Assist for FSP is not generating entries for FreeRTOS threads

RA Coding Assist

The Developer Assist functions are not present for modules that have been added to a RTOS thread. They are not present in the Project Explorer. You can only see these functions when they are added to HALCommon.


Synergy's watch point doesn't work

GDB Server RA

"Event point" function doesn't work on Synergy S1JA.


Sort Address and Binaries feature works incorrectly

Coverage plugin

Users cannot sort address and binaries by "Sort Address and Binaries" item in Coverage view.


Smart Demo unable to complete in e2 studio due to change in name of Boards

RA Configurator

The Smart Demo functionality for RA does not currently work. The project cannot be created successfully.


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.


_interrupt not resolving in GUI until property is changed

RA Configurator

For the RA family and the Flexible Software Platform (FSP), CTSU is different than other FSP modules in that the interrupt priorities are currently macros instead of run time options. This causes a problem where once added the DTC activation sources are not resolving in the GUI. To work around this please go to the Properties tab and change any property for r_ctsu, then the strings will resolve correctly.


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.


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).


Coverage result for variables is reset when switching debug session

Coverage plugin

Changing debug context in Debug view will reset coverage result of variables in the tab Data Coverage. The issue occurs on all debuggers that support the feature coverage. Please do not switch debug context when using feature coverage to avoid this issue.


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.


GUI will be not responding when scrolling after filter on Trace

Trace plugin

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.


GCCRX __rx_fini missing for C project (start.s)

Project Generator GCC RX

When creating a new GCC RX project __rx_fini is defined only in case of C++. #ifdef CPPAPP ... .global __rx_fini __rx_fini: mov #_rx_run_fini_array,r7 jsr r7 ... #endif In case of C this is not defined, please add this definition: .global __rx_fini __rx_fini: rts


[Memory view] exported WAV file in wrong endian

Memory View plugin

When exporting memory from the memory view in a wav format the memory is should be exported as little endian but is exported as big endian.


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.


The state of ON/OFF button is not reset when debug with new project.

Coverage plugin

When connecting to a project that had not used the feature Coverage in the previous. If the state of ON/OFF button is ON and other buttons still are disabled, it means the feature Coverage is disabled. Please turn the button OFF then turn it ON to enable the feature.


Trace view cannot show disassembly for some DPFPU instructions

Debugging RX

When using RX device which has DPFPU (such as RX72M), Trace view may not show the disassembly instructions if the address range includes DPFPU instructions.


J-Link's setting is not saved when setting change from control Panel

Segger J-Link

Currently J-Link settings that are set with the J-Link control panel do not save. This issue is caused by Segger’s F/W(JLinkARM.DLL). Segger have already released a fixed version (V6.50b or later).

This will be included by e2 studio V7.7.

[Workaround] There are two workarounds for this issue. One is to use a J-Link script file and the other is to manually replace the JLinkARM.DLL.

1) Please create a J-Link script and set it on debug configuration. J-Link script can be set on debugger configuration dialog's [Debugger]/[Connect Settings]/[Script File]. Please refer to J-Link User Manual for how to write J-Link script.

2) Although not recommended, there is another way to save J-Link settings. Please replace current JLinkARM.DLL to fixed version (V6.50b or later) on manually. JLinkARM.DLL can be gotten from J-Link Software and Documentation pack.

That is distributed in https://www.segger.com/downloads/jlink/#J-LinkSoftwareAndDocumentationPackBeta And Install that, then JLinkARM.DLL should be available on install folder. For example, in the case of RZ/A2M, current JLinkARM.DLL is put in DebugComp/RZ/ARM/Segger directory.


e2 GDB Server stopped working when setting Eventpoints

GDB server RX

When you terminate a debug session after running it for a long time (more than 45 minutes), GDB server sometimes crash.


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


Failed breakpoint looks to be set correctly after reloading.

Breakpoint at main will cause connection fail for SOTB

Debug Launch

When using RE devices with E2 or E2LITE emulator, connection will fail if setting a break point at main is specified in the debug configuration. In this case, please set the check "Set breakpoint at" to OFF at Startup tab in the debug configuration.


Ram/Rom Usage View doesn't display a warning message in case of invalid section

Memory Usage plugin

[Memory Usage] When using the memory usage view, if a memory section has an address which is totally out of memory range (e.g. section belongs to non-map area), the view does not display a warning message


[Welcome] "Renesas Synergy Samples" on [Sample] page links to incorrect location

Renesas Synergy

Selecting "Renesas Synergy Samples" on the Welcome screen will incorrectly display help for the Smart Browser view


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.


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.


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.


"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.


[Current Consumption] Even Monitor point is deleted, its information still be shown in Acquisition setting

Even if monitor points have been deleted, their information is still shown in acquisition setting dialog. Please re-check whether monitor points are available before setting.


After hot plug connection, program stops.

Debug Launch

When connecting to RX or RL78 with hot plug-in option, the target program will be stopped after connection. Please resume it from e2 studio manually if required.


"monitor ignore_continue_during_connect should" handling in synchronised cores mode

Multicore Debugging RH850

When RH850 multicore debugging in some situations the core synchronization settings are not set correctly. During initial launch when core synchronization is turned on, cores may be resumed unnecessarily after downloading binary.


"Target not in non-stop mode" error dialog is shown

Real-time Watch

"Target not in non-stop mode" error dialog is shown sometimes when starting debugging. This can also happen when the user executes debug operations rapidly. Even though non-stop mode is not enabled in GDB settings, GDB turns it on automatically while starting debug.


customer Issues with headless build

ARM GCC Plugins

e2 studio when executing the clean command as part of the build process will sometimes fail. This is because the command line length limit is reached. It can occur when cleaning a huge number of files or using deep nested directories. In this case please delete the files manually. This will avoid the issue.


[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).


CoreSight ITM: trace table disappear suddenly

Trace - CoreSight Plugin

When the content of the trace data is changed, the user is asked to refresh the updated data. After the update, the trace data editor is closed. The user needs to open the editor again to see the updated trace data.

[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, it's 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.


Smart Manual view menu toolbar action does not appear on Linux

Smart Manual plugin

On Linux OS, two actions of Smart Manual cannot be used: "Install New Smart Manuals..." and "Manage Smart Manuals".


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

IAR plugins

Workaround is to switch off parallel build (project properties > C/C++ Build > Behavior tab > Enable parallel build set to unchecked). After this workaround is performed, Pre-build steps and Post-build steps are executed during a build.


renesas_cc_converter crashes at build of sample program

Loadmodule Converter

renesas_cc_converter.exe might crash at build when using toolchains CC-RL or CC-RX. This might happen since e2 studio 7.0.


Build fail with S1JA project

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.


[RL78/G10 + E1] Strange behavior when step return

Debugging RL

When using RL78/G10, stepping over or stepping return will fail if a break point is used. In this case, please remove the break point and invoke stepping over or stepping return. This behavior is the specification for RL78/G10, because it only has 1 break point.


Project type -> IAR RX Executable missing

IAR plugins

Users are struggling to locate the IAR project generation menu items. The procedure for finding this is as follows: Just to check are you following these steps: File->New->C/C++ Project Click "C Managed Build" Click Next Find the IAR (Executable) entry


RH850 Multicore debugging can not suspend

Debugging RH850

When debugging on a multi-core device of the RH850, if the program is stopped at a breakpoint and then resume, debugger control may be lost. This occurs when debugging in synchronous mode. In that case, close the debugging session and restart debugging. And consider debugging in asynchronous mode.


Build fails when import a project with blank character in the the project name

IAR plugins

When using the IAR plugins with a Synergy device if the project name has a space within it will cause the build to fail. The build will fail with and error regarding missing header files.


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.


Debugger is disconnected when entering software standby mode.

GDB Server RZ

When using the RZ and debugging with J-link if the device enters software standby mode the J-link is disconnected.


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.


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}


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.


NullPointerException generated after excluding resource from build

RX GCC build plugin

When using the RX GCC builder and excluding either a .s or .SRC file from your project it can cause a null pointer exception on a subsequent rebuild.


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

Current Consumption View

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

GDB Server Synergy

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.


Program doesn't start from boot loader for RZ J-LINK

GDB Server RZ

When using mbed project with J-Link, the program may not work correctly if the program resumed after reset, because it doesn't quit the boot loader. In this case, download the program by using mbed drag and drop programming, and use e2 studio 6.x or replace J-Link dll to J-Link dll V6.16f which is attached to e2 studio 6.3.


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.


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.


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.


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.


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.


[Eventpoints][SIM] Program execution works incorrectly for Execution Address (PC) Eventpoint + trigger type = AND

Eventpoints plugin

When debugging RX simulator, the combination of event points will be treated as OR, even if AND is specified.


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.


e2 studio fails to restart initially after updating from 7.0.x to 7.1.x


When using the check for updates feature within e2 studio and updating from 7.0.x to 7.1.x the initial restart after the update fails. An error message is displayed. Subsequent launches of e2 studio work without issue. This is caused by the update to Java.


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.


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". This should solve the problem and allow e2 studio to work correctly.


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.


CodeGenerator cannot import AP3 project

Code Generator plugin

'AP3 for RL78' project file/ Code generator setting of other e2 studio project cannot be imported into e2 studio project even if the target device and toolchain are same.


[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.


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.


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"

Code Generator plugin

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


Previous toolchain version shown in build settings if changing configurations after clicking "Apply"

Managed Build

In the build settings dialog if you select a new build configuration or try to select the current configuration again after changing the toolchain version you will see the previously selected toolchain version displayed. To avoid this either click "Apply and Close" after selecting the new toolchain or click "Apply" then close the dialog.


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.


RZ/G debugger Renesas Device Support

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


[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.


[RZ/A1 Eventpoint] Eventbreak using Compare settings does not work

GDB Server RZ

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.


Build fails with secure builder required error after Migrating IAR 7.x tool chain project to IAR 8.x

Synergy Builder

The following workaround can be used to migrate projects with IAR7.x to IAR8.x 1. Add environment variable SECURE_BUILD_COMMAND: ${renesas.support.targetLoc:synergy-build} /isdebuild 2. Update Command Line pattern IAR C/C++ Compiler for ARM setting if following command missing ${SECURE_BUILD_COMMAND} 3. Update Command Line pattern IAR C/C++ Assembler for ARM if following command missing ${SECURE_BUILD_COMMAND}


IO Registers accessed with disregard for initial setup of register

IO view plugin

There is an issue that the reset values of a peripheral register that were different than the user manual was stating. The root cause is that the IO register view in the debugger does not validate the MSTP register settings before presenting the data for the peripheral that is being viewed.


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.


[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 a monitor point is set current consumption may be measured for a certain period even after user program stops.


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.


[RL78 G10] Strange behavior with Breakpoint at top main on G10 hardware debug

Debug Configuration RL78

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 breakpoint manually after the breakpoint hits. - If "Set breakpoint at" is specified in the debug configuration for RL78/G10, program will always break at the specified address. Please do not specify the "Set breakpoint at" in this case.


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.


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.


'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.


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.


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.


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.


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


The "Project Upgrade Required" pop-up does not appear on subsequent imports of the same project

Managed Build

The "Project Upgrade Required" pop-up does not appear on subsequent imports of the same project when you delete and re-import in the same session. To work around you can right click on the project and select "Upgrade Legacy Project" or alternatively shut down e2 studio and re-open it.

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.


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.

When you debug multiple project at a same time, if Source-only mode is used (Source button is checked, Bus and Disassembly button is unchecked) in Trace view, the number of column in Trace view can be duplicated each time Turn Trace On/Off button is checked. Please ignore the duplicated columns as it will always be empty, only the first 4 columns will have data. You can close and reopen Trace view to remove the duplicated columns (trace data won't be deleted by this action).

For the CC-RX and CC-RL the -ignore_files_misra option has been imrpoved to allow a subcommand file. This can reduce the command line which otherwise can get very long.
