TX2 (p3310) UART configuration

Hi @JerryChang
This topic 201881 realy works and helps us a lot. But, stty command can change baud rate temporarily. If we reboot tx2 baud rate will go back to 9600. So, we need config it when uart init. Could you give some suggestions?

We are so confused that baud rate has been setted to 115200, why it does not work?
