MINIDBG

MINIDBG is a RP2040 based debugger allowing debugging of all major interfaces(JTAG,SWD,SPI,I2C) from a PC over USB.

WHY

I designed MINIDBG because it is always annoying to have find my SEGGER J-Link and use the segger software comapred to being able to just start up openocd using thr rp2040.
