Oops, I really missed that mail, sorry.

This error message means that your cross-compiled binary does not run on
the embedded device (maybe the device uses different libraries than your
cross toolchain links agains).  To troubleshoot that, start with a
regular "hello-world.c" and continue to fw_printenv only if you have
this working.

Cheers
