MPC8544 doesn't have eLBC, so its LBC can't speak NAND directly, only via UPM (user-programmable machine). And with UPM we can support any NAND flashes. As for the original problem, it could be anything: schematics (I assume it's custom 8544 board), timings setup (OR/BR), or UPM array problem. Unfortunately it's hard to debug these sort of things without logic analyzer, so if you don't have one, I'd suggest to play 'trial & error' game. Cc'ing Wolfgang Grandegger though, maybe he has better ideas. -- Anton Vorontsov email: cbouatmai...@gmail.com irc://irc.freenode.net/bd2 _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
