Hi Grant,

I tried your .config file and was still unsuccessful with QEMU.

I diffed your .config file against that produced by 'make integrator926_defconfig', and there were no signficant differences.

Perhaps I am not having a Buildroot issue, but a QEMU invocation issue.

Do you recall the qemu-system-arm invocation that worked for you with the Linux kernel and RFS created by buildroot-2009.11?

Thanks.

Jim

I built for arm-integrator using HEAD back in
November/December, and it ran fine on qemu-0.9.1.  I didn't do
much with it other than boot it up, log in, and test the
virtual serial ports.

Not that I've found.  There were some articles written a couple
years ago that have step-by-step instructions, but they're
missing a step or two and are also now out of date in a few
spots.

Here's the .config file I last used -- AFAIR it was working at
that point:

# Automatically generated make config: don't edit
