I figured out the solution.
running the Jetson-IO I turned on the CAN-bus and I figured that was enough. and then, on Controller Area Network (CAN) — Jetson Linux<br/>Developer Guide 34.1 documentation
CAN page provided by NVIDIA - it mentions to use 0xC458. I changed that to 454 based on your
but I forgot to check the register for 0x0c303010 which were set to 0xC404 when CAN-bus was turned on Jetson-IO. After changing the register to 0xC400, it got connected.
I guess the registers are 0xC454 and 0xC400.
