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.
Regards,
Alexander
