That looks like the Pico SDK function isn't declared. Did it get installed in the lib directory? The cmake build process produces a maze of twisty passages all alike.

@kentindell
I added #include "hardware/irq.h" in mcp2517fd-rp2.h and all went fine. Cheers.

I'll keep this open. There's an update to the CAN SDK for C coming, and a new MicroPython release against it, so I'll check this doesn't happen again.
