I think the relocation itself works fine, when looking at the debug output. > Maybe some memory barriers are needed to stop the C optimiser mangling things? It can't really optimize across the call to the (now wrongly named) reloc_code in assembly. > Interestingly, ARM is adding gd->reloc_off while x86 is subtracting > gd->reloc_off.

Note, of course, that the value itself might well be negative. If, for example, the NOR Flash is at a higher address than RAM...
