Cannot accurately set CAN BUS communication bit rate on Jetson AGX Xavier with BSP 32.7.2 and failed to communicate with external device

Hi vbhm,

Are you using the devkit or custom board for AGX Xavier?

Could you also verify with the latest R32.7.4 or R35.5.0?

[   85.580480] mttcan c310000.mttcan can0: bitrate error 0.2%
[   85.580652] mttcan c310000.mttcan can0: Bitrate set

It seems there’s bitrate error 0.2% in your dmesg so that it doesn’t match the exact 250000.

Please also check if the following topic could help for your case.
