Hello, unfortunately I dont have this board for testing. I see you are already having branch, so you can let me know once its working or you are having some issue.

I have not worked with RP2040. And I do not know all the features of the SPI interface. I changed the SPI settings and changed the quartz frequency. It does not work. I need a speed of 1000000. I connected two CAN interfaces and connected them on a cable. I checked who transmits and who receives. Your adapter transmits five... CANsend, and then goes into nirvana. I look messages on another CAN. Candump does not work at all.
