Hi Giriprasad Sorry for the delay, Which Serial Port are you using for the application ? Because the serial port 2 is used for the Kernel for communication, so you can use serial port 0 or 1,. One more think right now I do not have the hawkboard in order to test it, let me check some possible solution and send to you.
