[Buildroot] Buildroot for AT91RM9200-EK?

Just to make sure I'm not spinning my wheels, has anyone gotten Buildroot
(22987 is what I'm using right now) working for the Atmel AT91RM9200-EK
board (Atmel AT91 ARM9)?


I've got the kernel booting okay, but as soon as it goes to run
/init (really, busybox) wackiness ensues. It traps in clear_user trying to
zero out part of the loaded ELF. GDB+BDI suggests that the address passed
from padzero to clear_user is bogus, but I'm not sure I'm trusting what it's
telling me (some of the other stuff on the stack trace looks questionable).


readelf-h suggests AFAIK that everything is built as OABI. (I may restart
from the beginning with EABI, but I'm not sure how U-Boot on the EK was
built, and I'm not sure if that really matters. But U-Boot does "call" the
kernel to start it.)


Thanks for any insight.
