Hi
My omapl138 board stop booting when it has to mount filesystem.
I have made this board much simpler than experimenter kit. I use a 4 Gb SD card which works fine on my experimenter kit and also use the same SOM
so i can hardly think of problem with SD or environment Variables. Following is a print of environment followed by debug output.
Thanks.
