<p class=MsoNormal>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)?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’ve got the 2.6.25.10 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).<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>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.)<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks for any insight.<o:p></o:p></p>
