I use Jetson Xavier NX Developer Kit.I use the program to open UART1(/dev/ttyTHS0, The 8th and 10th pins of 40pin gpio) after booting,UART1 cannot communicate.
If use cutecom to open UART1, if I open it too fast, it will get an error(No such file or directory)(But I waiting for a while after booting will not),Turn it on again to use it normally. Then use the program to open the serial port to communicate.
My purpose is to write a script that can be used to modify UART1 permissions, and use the program to open UART1 for communication. Now I’m stuck here.I hope to get some help,thanks.
