I’m closing this topic due to there is no update from you for a period, assuming this issue was resolved.
If still need the support, please open a new topic. Thanks

Hi aymen.baig,

What’s your Jetpack version in use?

Have you tried to short TXD/RXD to verify loopback test for UART?

Please share the full dmesg for further check.
