Hi @D_D97 ,
Thank you for your interest in the NXP MIMXRT product, I would like to provide service for you.
I did a test, I connect MIMXRT1170-EVKB board CAN1(J83) and MIMXRT1050-EVKB board CAN2(J11), CAN communication works normally. So I think you can refer to what I do.


For hardware modification, you need to mount R2057 and R2058.

For software, you need set CAN1 pins. You also need modify some code based on CAN1.

Wish it helps you.
If you still have question about it, please kindly let me know.
Wish you a nice day!
