You didn't let RedBoot write the image to the FLASH!  Look at the
messages above - there is no "Program" from your image location
of 0x200000.  

Try leaving out the "-n" option - that tells RedBoot that all you
want to do is update the FIS entry and not actually write any data
to the FLASH region.  n.b. the "-n" option is just a hack for those
that want to write to the FLASH and later tell RedBoot how to manipulate
it via FIS.
