Hi Max,
Thank you for the reply.
It doesn’t run when the psram is removed.
I havn’t been able to test using a debugger yet. I’m having problems trying to get my pico to act as one.
I have my current board.json below. I copied it from the rppico2w board.json but changed the ram size and name. Is there something else I need to change?
Thanks again for your help.
