pico-serprog

Slightly less terrible serprog implementation for the Raspberry Pi Pico and possibly other RP2040 based boards. Based on pico-serprog by GitHub user "stacksmashing".

Pinout for the SPI lines:

Pin Function
GP5 CS
GP4 MISO
GP3 MOSI
GP2 SCK

Example

Substitute ttyACMx with the actual tty device corresponding to the firmware.

Read chip:

flashrom -p serprog:dev=/dev/ttyACMx -r flash.bin

Write chip:

flashrom -p serprog:dev=/dev/ttyACMx -w flash.bin

License

As a lot of the code itself was heavily inspired/influenced by stm32-vserprog this code is licensed under GPLv3.
