What exactly are you trying to do? zImage is for Linux. If you want to
boot Linux on the PC use LILO or GRUB. There is no support in RedBoot
for running Linux.

If you have indeed run all the tests, then you have successfully
loaded and run eCos. Just build your application as described in the
documentation and load it in exactly the same way.

eCos programs need the eCos kernel to run. You can configure eCos down
to eliminate the kernel -- RedBoot is an example of this -- however,
most program do need the kernel.
