IDE-22266

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.

IDE-22184

[PG] missing elements in RX630 vector table

Device Support RX

For the RX630 device some elements (RIIC3) are missing in the vector table and subsequent elements have been shifted by that.
 
As a result, affected interrupt handlers will not work correctly. Correcting the vector table manually will solve the problem.

IDE-19310

[Profile] Displayed data is not reliable If Trace view is OFF

GDB Server RH850, GDB server RL78, GDB server RX

If the Trace view is off, the Trace capacity (will be also used for Profile) is set to default (usually, this is the minimum capacity). This then means that the Profile data is not reliable.

To workaround this issue you can set the Trace capacity to maximum even if Trace view is off. When turning on the Trace view again it will use the previous setting rather than the default.

IDE-18830

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.

IDE-18748

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.

IDE-18746

When changing the device in the Synergy configurator the project is not updated in the Smart Browser

Application

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

Debug Configuration RL78, Project Generation Core

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

Visual Expressions plugin

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

IDE-16874

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

Debug Configuration ADAS, Debug Configuration RZ

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 commands in the debug configuration.

IDE-16830

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.

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.

IDE-9507

Setting breakpoint in function referenced in expression view causes debugger to hang

Application

Setting a breakpoint to a function which is referenced from an expression in the expression view causes the debugger to hang when execution is resumed. When this happens e2 studio must be restarted to resume normal operation.

Steps:
Add a function "test(int)"
Set a breakpoint in it
Add an expression "test(5)"
Resume

IDE-9494

Memory view address caption should match to endianess

Memory View plugin

Users may misunderstand the data order in the memory view due to the address column heading.

The "Address" caption of Memory view is always the like "0 - 3", "4 - 7" regardless of the endian which is selected.

IDE-9393

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.

IDE-9338

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.

IDE-9101

Cannot launch debug session when breakpoint cannot be set

Debugger

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.

IDE-9090

Multiple breakpoints set for multiple symbol files

GDB

When the same symbol files are downloaded on to 2 different processes and the User sets a source breakpoint, GDB will set the breakpoint on both processes.

This will cause the system to appear to have only half the number of breakpoints.

IDE-9057

[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

IDE-9045

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.

IDE-9032

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

CCRX: Warning dialog shows many times on Turkish OS when input 'i' key for e2 studio location

Installer

Problem:
An error occurs by project operation when a non-ASCII character was used for the file name or the folder name.

Workarounds:
Please don't use non-ASCII characters for the file name or the folder name.

IDE-7498

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

Application

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 affect both for configuration management dialog and the configuration creation dialog of Optimization Assistant.

IDE-7423

Disassembly view does not always update on initial opening

CDT

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.

IDE-7419

RL78 on-chip debugging and reserved areas problem

Application

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 behaviour 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.

IDE-7412

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.

IDE-7403

Indexer setting not saved.

CDT

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.

IDE-7333

1ms refresh interval in expressions using RX Simulator does not work

Real-time Watch

When using the RX Simulator with real-time expressions if you use 1ms real-time interval the expression view goes blank. On suspend, e2 studio appears to hang while messages are processed.

Reverting the interval to 10ms works well.

IDE-7298

[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.
