How to build

How to use

Use with pyOCD

Install pyOCD

python3 -m pip install pyocd

Run pyOCD and GDB connection

pyocd gdbserver --target rp2040_core0

Run GDB in another terminal.

gdb-multiarch, which is installed with apt, seems to fail to recognize the architecture correctly, so download the toolchain from Arm's website and use GDB in it.
