I have a linux bootable SD card which is working fine. The problem I am facing is that the ttyPS0 port does not echo back the characters entered. It accepts the characters and responds, for example, if I type "ls" then it lists the directory but does not echo back "ls"
I tried setting "stty -F /dev/ttyPS0 echo" but I get an error "stty: /dev/ttyPS0: unable to perform all requested operations". I checked the .config file and both CONFIG_SERIAL_XILINX_PS_UART, and CONFIG_SERIAL_XILINX_PS_UART_CONSOLE are set to y.
What could the problem be? How do I get an echo on ttyPS0?
