    I had the same issue when I followed the tutorial here

    The tutorial also uses gdb in eclipse to debug, and I cannot see the source code when I flashed the binary by clicking debug. I solved this by simply correcting the device name of the debug session. You could follow this tutorial to see if you have set up the device name correctly when you create debug session. I'm not sure if this would solve your problem, but it works for me.
