I’m trying to use piodebuggdb on a custom stm32 board with a BMP and while GDB starts it does not connect to the target. Uploading via the BMP works fine and I can also run gdb manually. Where should the gdb start-up commands come from that contain the target command, etc. I see where that’s defined in the platform for the upload but where is it defined for debug?
Here is what I get:
tve@soumak /h/s/g/g/hello> piodebuggdb -e arduino
