Thats not going to work. Instead, you should use the objdump included in the rockbox dev tools or another ARM disassembler.

Decompilers don't really exist in the sense you're probably thinking. Generally the best the computer can do is disassemble the binary to show you the actual assembly instructions (in this case they would be ARM). Then you read those to try and figure out what they do, or at least figure out enough to work on a port.
