Nano ttyTHS1 receive data lost

THank you!

For regular device, the baud rate tolerance range is +/-2%。
So the max error between sender and receiver is 4%, which is the max accecpted error in uart comm for theory.

The solution seems like this:

Set the baud rate to (REAL value) * 1.02, in order to receive +/-2% input.
Then set dts entry to -200 in order to send REAL baud rate.

It’s crazy to do this trick, But I have no idea for the right way.

Would you please verify this guess?
Thank you!!

Since there is known constraint in Jetson Nano, please give it a try with the external device and see if it works.
