I would like to ask if I adapt platformio to this board, is the tool chain used consistent with the one described in this file? : https://siliconlabs.github.io/arduino/package_arduinosilabs_index.json

I would like to ask if I adapt platformio to this board, is the tool chain used consistent with the one described in this file?

Unfortunately, it's not.

Hi, I am adapting platformio for MG24. I have successfully completed the compilation, and I can burn the compiled firmware into MG24 through other methods, and it can run normally. However, when I try to burn it using openocd in Platformio, an error occurs that efm32s2_g23.cfg cannot be found. I think this is because the openocd tool I downloaded does not support efm32. So I try to directly copy the openocd tool described in https://siliconlabs.github.io/arduino/package_arduinosilabs_index.json, and then the following error appears: Open On-Chip Debugger 0.11.0-g228ede43d-dirty (2022-12-22-20:10)

Info : auto-selecting first available session transport "swd". To override use 'transport select '.
Error: flash driver 'efm32s2' not found ，I'd like to ask if there is any solution to this?
