What if you make an init app or script that just creates a file on the
JFFS2 fs?  Then you could verify it was created by rebooting the board
and inspecting the filesystem from U-Boot.  That would tell you that the
code is executing as expected at least.  You could dump debug output to
this file for later use too.  If that works, it'd be interesting to know
if a statically linked hello world app printed anything out.  If not,
you could narrow the problem down to a serial/console issue.

A JTAG/XDP debugger could help too.  Maybe dumping the printk buffer in
Linux would show some kernel messages that never made it to your serial
port.
