Hi,

I just set up a new project using the ESP32-c3 and wanted to run the debugger.
The code gets (re-)build and the debugger start but dies without error.
Going to the debug console I can see:

undefinedFileNotFoundError: Traceback (most recent call last):

I suppose the missing riscv32-esp-elf-gdb is my issue, but should this not be installed according to the dependencies?

This is explicitly disabled for Arduino because it’s supposed to be in toolchain-riscv32-esp:

Try adding

platform_packages =
   espressif/tool-riscv32-esp-elf-gdb

in the platformio.ini.

thanks for your support. I did add and listing dependencies this extra package is shown, but the debug console output did not change.

Furthermore I just noticed my toolchain-riscv32-esp is version 8.4.0+2021r2-patch5, but seems like 12.2.0+20230208 is the latest. pio pkg update does not give my any updates. Plaformio itself seems to be latest 6.1.13.
any idea why this wont update?

It’s correct for framework = arduino projects to be built with 8.4.0, the GCC12 toolchain is only used for framework = espidf.

In any case, Arduino projects should still be debuggable and the toolchain should have GDB in it. This is definitely a bug. Please file an issue in Issues · platformio/platform-espressif32 · GitHub along with the minimal possible platformio.ini that reproduces this error.
