Well the obvious method is to attach a JTAG debugger and step through
the code.

If you don't have such a debugger it will be more complicated, but you
can try to use the "poor man debugger", i.e. printf statements in the
code.

The other method is to think again what differences there are between
both boards.  If they behave differently, then there have to be
differences.  If the software is completely the same, then maybe the
sequence of events before you boot the image is different.  Try to
execute _exactly_ the same commands from power-on-reset and note any
differenc in output.

Sorry, this is as much as we can do from the distance.

Cheers
