I meant that e.g. mvblm7 board (=MPC8343) works like a charm from current mainline U-Boot. My latest MPC8377 board does not even start without your suggested 4 nops. It does not start (i.e. serial line completely dead) with any USB functionality defined. I also have random hangs depending on activated code, e.g. CONFIG_CMD_something or SPI drivers etc. To me it looks like an alignment problem *somewhere*. As said before I'm still digging and try to get more useful information. Do you think porting the board to an earlier (maybe 2009) version is worth a try ? I could start bisecting if we could get a stable version. Regards, Andr?
