sorry.
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?
