Hello,
I have a uart1 problem. when I first open the /dev/ttyTHS0 serial port, It is good when no data received or transport data outside.However, once the URAT1_RX receive some data, the serial port will report an error immediately or after a few seconds. It only happened at the first few times opening the /dev/ttyTHS0 serial port.After the first time or first few times, the /dev/ttyTHS0 can reveive data stable.
The error reported by cutecom tool is Device error “No such file or directory” or “Resource temporarily unavailable”.
That is the serial console/debug port. Useful for logging when boot fails. Basically, before disabling that, you had a conflict from your application and the serial console running simultaneously in conflict on the same port.
