I am currently using /dev/verdin-uart1 serial port. However, when I send data, it echos what I send back to the input. I currently have the echo bit off. In fact, in the termios2 structure c_lflag, it is 0. Yet I am still getting the issue. I am using termios2. Not sure why this is happening.
If I switch to verdin-uart2, I don’t have this issue. It would seem that maybe the driver is not working correctly on the RS485 port? And I do not have anything connected to the port output. I am using the verdin dev board for this testing. Maybe there is a jumper that needs to be changed?
