Failed to debug Renesas RL78 Project

[RLusseni]

Hello IAR team,

I want to use your IAR C-Spy Debug plugin to debug an RL78 application. The debugging configuration is auto-generated by the IAR Build plugin, both plugings on the latest versions. (IAR Build v1.20.1 and IAR C-SPY Debug v1.20.1)

Trying to debug the EW project results in the following error message:

The output file "FirstRL78.out" has been generated/built with the IAR Build plugin, does exist at the printed location and is not write-protected. Also building the output in the EW IDE and debugging with the C-SPY plugin results in the same error message. Debugging the file in the EW IDE is working flawlessly.

Debugging configuration is as followed:

Hi @RLusseni. Debugging support comes with the next release of IAR Embedded Workbench for RL78 which is v5.10. Planned for Q1 2023.

[RLusseni]

So it will be necessary to update the EW IDE and its licensing to make use of the C-SPY plugin?

[micaelbo]

Yes, this is correct @RLusseni.
