I've been using USB to transfer data from RP2040 to CM4 but would like to implement something faster (right now max around 600kB/sec despite it being 12mbps). I want to send a 100kB block to the RP2040 as quickly as possible so I'm thinking to implement this as a SPI write:
-RPi CM4 as SPI Master
-RP2040 as SPI slave, 10mhz (seems this is max speed with 12x oversampling from my reading)
-use as write only interface with SWD to initiate
Has anyone seen any libraries doing something similar to above - seems talking to RP2040 from RPI should be a common request but better if I can use some library instead of reinventing the wheel. Thanks!
