I want to test the Serial ports of "Starterkit PicoCOMA9X Linux". The Problem is that I can send data by using "echo Hello > /dev/ttymxc2" which is mentioned in the "F&S i.MX6-SoloX Linux First Steps", but I can't receive any data from port when I use "cat /dev/ttymxc2". Or even with using "termios". Is there something missing?
Any help and Suggestion would be appreciated.
