Try connecting gdb and see what it says about the crash.

Are you sure Redboot RAM has been linked to run at 0x03000000. It is
rather high in memory. Normally it goes much lower. Try loading the
elf or srec so you don't need to use -b and -r. Redboot itself will
decide where in memory to load RedBoot RAM.
