Do you think it would be possible to use the Pico/Tiny2040’s USB drive capabilities rather than requiring a separate SD card interface? This would lower the barrier to entry and make it even easier to get started with CP/M on the RP2040 platform by just dragging files onto it from a computer

Is it possible to output the terminal to serial port instead of (or in addition to) USB? I’d like to hook this up to a DEC VT510.

I am using a stock RPi 2040 board on a Maker Pi Pico breakout.
The Maker board has a built on uSD card reader.
The Maker uSD uses the SD1 pins (SCLK-GP10, MISO-GP11, MOSI-GP13, SS-GP15).

I've tried modifying the "pico_sd.h" file to change the SPI pins, but every time I run, it keeps failing to init the SD card and the debug output tells me it is using the original pins defined in the header file (even tho they are commented out).

Also, in enabling the debug output, the compile fails on the "BOARD" not being defined.
I even added a define for it in the "pico_sd.h" file and... no joy.

WHAT am I doing wrong (or not doing) that is needed to fix this problem?
