Mttcan does not transmit but receives fine after bus-off recovery

We are using Jetpack 5.1. The issue we are seeing is that the mttcan is not sending any messages but is receiving fine. Below is the screenshot of me trying to send a can message and read the same back on the can line.

The topic was closed in July with the “solution”: “Both the next Jetpack 5 and Jetpack 6 release should include the fix.”

Hi Agtonomy,

For the bus-off recovery issue on mttcan driver, the fix should be included in both the latest JP5.1.4(R35.6.0) and JP6.1(R36.4.0). Please just verify your AGX Orin with either releases.

Thanks, we are on 5.1.2, will check the 5.1.4.
