Another problem I have with relocation is that it makes debugging with JTAG debugers more difficult. The addresses of symbols in the ELF target are no longer valid. Of course, you can load the symbols at an offset from the original location. But one has to first enable debug prints, find the relocation offset, use it while loading the symbols before you can do source level debugging.
Actually you don't need recompiling: simply set a breakpoint at the entry of relocate_code and once you hit the bp, look up r2: it contains the destination. If you want the offset rather than the absolute address, set the breakpoint right after the 'sub r9, r6, r0' round line 222: r9 will then give you the offset. Unload the current symbols, reload the symbols with the relevant offset, and there you go.
