0.2 pcb - SPI on ActiveBOM for RP2040 isn't standard, requires special build flag #7

Closed colinoflynn closed 4 months ago

The activebom uses the same SPI for everything, which isn't a RP2040 optimized one. This requires the build flag -DPICO_DEFAULT_BOOT_STAGE2=boot2_generic_03h.

See https://github.com/newaetech/sonata-rp2040 for example of this.

This will limit the speed of XIP as it uses only the generic 03 read command.
