Using a LED for debugging is time consuming. And you won't see which code still uses BSS before relocation as such code does not have to fail (it still might work). I prefer reading source. Using JTAG should help too, but I think, using JTAG and a debugger might got somewhat harder, at least after the code got relocated. Anyway, a JTAG-debugger could help a lot searching the stuff which currently goes wrong before relocation. I assume single stepping the few dozen lines which are executed before relocation could be done in a few hours and it should reveal most of the code which accesses BSS before relocation.
