The most common cause of this sort of thing is that the application is
being loaded over the top of RedBoot. The download fails when it
overwrites a piece of code or data that is being used by the download.
Check that the application has not been built with FLOPPY startup, but
with RAM startup; and that you are using a fresh build directory, not
the same one redboot was built in.
