I tried to find suitable tools to trace the ROM code, because objdump
output only is not the best thing to going throught it.
I found some nice software for wince at
http://www.rainer-keuchel.de/software.html
there is (dis)assembler and debugger, but I am not able to do much with
it.
Another idea is to use arm emulator (e.g. ARMware) to trace somehow
(?!) the code..
Any other disassembler option?
