I’m currently trying to get the Copperhill PiCAN duo to work on the RockPi 4B. I have successfully enabled SPI1 CAN0 with the following .dts file:
I have been unable to get the second CAN channel (CAN1) to work however. I am fairly new to modifying .dts/.dtbo files so am not sure exactly what changes to it are needed. For reference below are the .dts files I have tried using for CAN1 (still on SPI1)
Any help with this would be greatly appreciated, thanks!
