Are you following this instruction t do the setup: Controller Area Network (CAN) — Jetson Linux Developer Guide documentation (nvidia.com) ?
Which JetPack SW?

Yes, based on this, my Jetpack version is 4.6.1, and the L4T version is 3271

“Normal can is enabled, but it suddenly fails during operation. I have sent you the log of the failure, but it will be fine if you power off and restart it. When there is no communication, the device status also appears to be incorrect, such as overclocking.”

Hi,
Are you able to try Jetpack 4.6.3(r32.7.3) or Jetpack 5.1(r35.2.1)? These are later releases for Xavier NX.
