I am not sure what is going wrong, but you might find using the arm
simulator, either naked or inside gdb, an easier way to debug your
startup code.  There is a useful debug statement commented out in the
sim code, (look for #if 0 in the file sim/arm/armemu.c).  If you
enable this it will print out the PC and binary value of each
instruction as it is executed.

Cheers
