Nano 2GB ttyTHS1 unreliable above 460800 baud

I have seen various conversations around this but I have not been able to dig up a solution yet.

I am trying to connect to the UART on J41 at 921600 baud, but am unable to get clean data.

I am connecting from an Ubuntu laptop with an FTDI adapter.

460800 baud and below work with no issue.

I have been able to run 921600 when connecting to another FTDI adapter on one of the Jetson USB ports.

I have tried different serial terminals and other test code aside from our own code and still have the issue.

Any help would be greatly appreciated!

hello nunderwood,

are you using two stop bits? there’s see-also topic for your reference, Topic 72684.
