Although I don't know this board, here are a few questions :
- are you sure that you enabled the correct serial driver and that it is
linked to the zImage and not build as a module ?
- are you sure that you enabled "console on serial port" in the config ?
- how can you be certain that the serial will appear on ttyS0 and not ttyS1
or another one (the kernel might detect another serial port which it
assigns ttyS0)
- is it possible that you have trouble with the endianness of the image ?
example: little endian image loaded on big endian CPU ?
Regards,
Willy
