can call, or do I just need to inline "lmw"? I seem to be having a similar problem to Sam, where U-Boot crashes when relocating U-Boot to SDRAM. It crashes in relocate_code, which is probably a burst read/write problem (from reading Sam's posts).
Right. It crashes when the CPU starts instruction fetches from SDRAM, using burst mode to fill the cache lines.
