| Key | Summary | Component | Description |
| IDE-66074 | The behavior of 'Restart' is same as 'Reset'. | Debugging RA | When debugging RZ snd RA family devices, when the restart button is pressed, the PC does not stop at the top of the main function and instead the program will run to the 0xffff0000 address. Workaround is to click resume until the main function is hit. |
| IDE-65862 | [IO Register] Set OA Event on selected register does not work in "Selected Registers" tab | IO view plugin | When using the IO Registers, the Set OA Event feature on the Selected Registers tab does not set eventpoints. |
| IDE-65798 | Execution Address Eventpoint for J-Link ARM not working | GDB Server RA | When debugging ARM devices with J-Link, execution address event on Eventpoint view is not supported. |
| IDE-65606 | [HotPlug] Cannot suspend program when restarting hot plug project | GDB server RX | When using hot plug-in connection, please don't use 'Restart' from the button on the e2 studio toolbar. |
| IDE-65603 | [HotPlug] Cannot debug project by using hot plug function. | GDB server RX | When using hot plug-in connection, once the connection with hot plug-in is disconnected, the next connection may fail. After the hot plug-in connection, please restart the target with power-on reset. |
| IDE-65107 | [Application] Cannot change Toolchain version | Toolchain Management | When using the RZ Smart Configurator support for FSP, the [Renesas C/C++ Project Settings] option > Select [Change Toolchain Version] feature available from the project pop-up should not be used. Please change toolchain version using the Build->Settings->Toolchain tab. |
| IDE-65041 | e2 studio seems to hang if Trace is enabled and/or trace start event is set for RL78/G24 with E2LITE. | Eventpoints plugin | When using Trace Start/Stop event on Eventpoints view, Trace view should be closed before reconnecting debug |
| IDE-65002 | [Linux] RH850 debugging is not working with CC-RH v2.04 | Debugging RH850 | When using the Linux host operating system and debugging RH850 projects that are using the Renesas CC-RH is v2.04 there can be problems with stability and operation of the debugger. Issues which you can encounter are listed below: Step Resume/Over/Into does not work as expectation. Sometime stuck at boot.asm/cstart.asm Sometimes cannot read register. |
| IDE-64353 | User pack creator does not load if project is not chosen | FSP Pack Creator | When selecting an FSP project in Project Explorer for creating a new FSP custom user pack, the top-most folder of the project should be selected. Selecting an other element may result in the User Pack Creator dialog not being opened. |
| IDE-63055 | RZ/T CM3 reset does not work - again | GDB Server RZ | When debugging CM3 core on RZ/T1 and a reset is required, please disconnect debugging and re-connect again. |
| IDE-63042 | Issue with project path containing spaces in IAR EWARM 9.40.1 | DDSC Device Partition Manager | When using Device Partition Manager with Trustzone devices on EWARM-9.40 if there is a space in the project folder name then the DPM may fail to start. Workaround is to use EWARM-9.32. |
| IDE-62641 | PC doesn't stop at the reset vector on reset for RZ. | Debugging RZ | When debugging RZ devices, PC will not stop at an address of reset vector on reset. Program will run in a short time after reset, and then, the program will be halted. If the program is built for RAM debugging (without using boot loader), the program will not run after reset correctly. In this case, please re-download the program (please don't forget to set "Reset after reload" option to 'No' on Debug Configuration) after reset, or disconnect the debugging and re-connect. |
| IDE-62233 | Cannot specify JLink serial number explictly in debug config | Debugging RA | Some JLink emulators fail to show up in the selection dialog on the Debug Configuration. If a dedicated connection is required in this case then the serial number can be specified in the Additional Server Parameters field on the Debug Configuration. Format is: -uSelect= USB=serialnum where "serialnum" is the serial number reported by either the JLink selection dialog or the JLink Configurator Tool. |
| IDE-61617 | [RX] Renesas Coverage is still enabled after disabled | Coverage plugin | When using RX with the Renesas Coverage feature. The Renesas Coverage view is still working after coverage has been disabled and the debugger re-connected. |
| IDE-61423 | RASC not creating hal_entry.cpp for C++ blinky projects | DDSC/FSP Smart Configurator | RASC currently does not support C++ project creation fully (as opposed to C project generation). |
| IDE-61365 | Timer event can't be allocated when break event is used (RX26T) | GDB server RX | When debugging with RX and 2 event break points are set, timer start for data access can be set but the timer stop can't be set. |
| IDE-61156 | [RX26T] Execution address events is limited by 4 for Trace/Performance | Eventpoints plugin | RX26T The spec of the device should be: - 8 execution address events and 4 data access events (same as RX6xx) ・For hardware break or break events, 8 execution address events and 4 data access events can be specified (same as RX6xx) ・For trace event (start/stop/record), 4 execution address events and 2 data access events can be specified (same as RX2xx) ・For time measurement event (start/stop), 4 execution address events and 2 data access events can be specified (same as RX2xx) Currently, the resource for execution address events is up to 8 events. which is not correct. |
| IDE-61037 | Build error occurs when adding new Build Configuration | CCRH Build plugin | CC-RX/CC-RL/CC-RH project: Build error occurs when executing Build with a new Build configuration you added. At that case, please specify the toolchain and device to your project. After opening the project, this can be achieved via the Project Explorer, project context menu. On this menu access the "Renesas C/C++ Project Settings" and use the "Change Device" and "Change Toolchain Version" features. |
| IDE-59574 | Breakpoint's Ignore count does not work with RL78 | GDB server 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. - Ignore count of the breakpoint does not work. - 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 operations, 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. |
| IDE-59440 | Disconnection of RA board allowing the user code to execute does not work when using semihosting - documentation support | GDB server | Disconnect an RA board with the "Continue" option (allowing the user code to execute after disconnecting from JLink) does not work when using semihosting. To work around this make sure you have conditional code for when the debugger is not connected, e.g. semihosting_printf( ... ) { if (CoreDebug->DHCSR & CoreDebug_DHCSR_C_DEBUGEN_Msk) { printf( ... ); } } #if semihosting #SAFE_PRINTF( ... ) semihosting_printf( ... ) #else #SAFE_PRINTF( ... ) printf( ... ) #endif Additionally, the use of an updated hard-fault handler to catch this situation would also help. |
| IDE-59435 | File path, file name on profile view is empty when debugging with RX GCC | Profile plugin | The filename and file path cannot be displayed when using the Profile feature on Linux OS. |
| IDE-59377 | [Debug Configuration] OCDID's value odd placed | Debug Configuration RH850 | When opening the debug configuration for E2 (RH850) or IE850A (RH850), the value of OCD ID may be displayed on the invalid location. In this case, please expand 'Flash' node on Connection Settings. |
| IDE-59342 | Chart work incorrectly when set Monitor Points Consumption Current View | Current Consumption View | Workaround: If user using monitor point with Current Consumption, Chart will be displayed normally when the user press and hold the mouse on the horizontal scroll of the range of time. |
| IDE-58871 | The value for the register msplim and psplim is displayed as 0. | GDB Server RA | The register value for msplim and psplim will be displayed as 0 in Registers View, when using Cortex-M devices which support TrustZone via E2/E2LITE emulator. Please refer to the value value of msplim_s/msplim_ns or psplim_s/psplim_ns insterd. |
| IDE-58693 | Emulator selection doesn't list the connected emulators on Linux. | Debug Configuration | Debug configuration for E2 or E2LITE emulator will have the selection of serial No. of the emulator and it can be selected from the list of emulators which are connected to the PC. But this feature will work only on Windows. In case of Linux, please connect only 1 emulator to the PC to use the emulator with e2 studio. |

| IDE-47191 | Build Error Sometimes Overlaps Code Line - Display Resolution | Eclipse Platform | In certain situations the errors that are displayed after a build will overlap the source line in the editor window. If this occurs scrolling the editor view up or down seems to resolve this. If this becomes a common occurrence it is possible to stop this happening by switching off the code mining option. This is available in the Window->Preferences page. In the section General->Editors->Text Editors. The option to switch off is named Show code minings for problem annotations. Change this setting to None. |
| IDE-46896 | Project imported from Windows build fail in Linux | ARM GCC Plugins | If copying a project with it's build output directory been Windows & Linux, or moving it to a new location, you need to do a clean and rebuild to avoid build errors. If storing a project under version control avoid including the build output directories. At a minimum exclude the *.d files which may contain system specific paths. |
| IDE-46110 | DPFPU registers always show 0 for J-Link (RX). | GDB server RX | Some RX devices such as RX72M supports double precision FPU registers. But when debugging it with J-Link, the registers is displayed as 0 in Registers View and writing a value to the register will be ignored. |
