Yes, I did this some time ago (for the 2009.11). 

{It was qemu-system-arm --version QEMU PC emulator version 0.11.0
(qemu-kvm-0.11.0), Copyright (c) 2003-2008 Fabrice Bellard, BUTY this
will not make the difference I guess}

The whole trick is that no need to have a KERNEL config to start with
(the file system... is nothing special) 
If you want I can send you a kernel config ... that is working for my
QEMU build (it is based on the kernel versatile_defconfig).
{ I even have build a booting ARM-QEMU from the buildroot-git a couple
of days a go.}
 

>>Do step-by-step notes exist for how to do this for ARM that were

Booting the kernel and roofs in QEMU can be done by a 1000ways, it
depends on your creativity and Linux-skills how you do this (disk-image/
nfs-boot / .... etc ) 

>>Ultimately, I might like to get Buildroot/QEMU working for a
particular ARM processor, but for now, a working

I know ... having BUILDROOT 'build-in' support for a QEMU-ARM platform
(as well as other QEMU platforms) would be nice, and I guess it is on
many buildroot users their wish-list.

>>A general purpose Buildroot/QEMU howto for ARM might serve as both a
worthwhile regression test, and primary support >>document visible at
the Buildroot web site.

Hi Lionel,

you mean: converting package/sdl/sdl.mk to autotools infrastructure will
solve the problem ?

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two and are also now out of date in a few spots.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:

I would be interested in looking over your .config file.

I think what I am missing may be on the QEMU side, not the Buildroot side.

What qemu-system-arm command do you use to bring up your virtual machine?

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two and are also now out of date in a few spots.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 # Wed Dec 16 09:10:07
2009 # BR2_HAVE_DOT_CONFIG=y BR2_VERSION="2009.11-git"

[Buildroot] BE: Buildroot How-To for QEMU/ARM (Jim Thomas)

[Jim Thomas]

I've made some progress.

If I use the Linux kernel built based on the following *Buildroot* defconfig:

  integrator926_defconfig - Build for integrator926

then the kernel does not boot at all.  There is no console output after 'Uncompressing Linux... done, booting the kernel.'.

If I build the kernel using the *Linux* (not Buildroot) defconfig:

  integrator_defconfig - Build for integrator

then the kernel still does not boot.

However, if I build the kernel using the *Linux* (not Buildroot) defconfig:

  versatile_defconfig - Build for versatile

then the kernel boots!  (Not all the way, more on that below, but much more works now.)

This may account for Noel's success, where he mentioned in his posting that he uses 'versatile'.

Part of my confusion is because Buildroot offers 'integrator926_defconfig', whereas the kernel offers 'integrator_defconfig', and Buildroot does not appear to offer 'versatile_defconfig' corresponding to the kernel 'versatile_defconfig'.

Since it is probably easier to change Buildroot than the kernel build environment, an improvement might be end-to-end consistency, where Buildroot offers 'integrator_defconfig' and 'versatile_defconfig' that flow uniformly through to the kernel build.

If it is practical to change Buildroot 'integrator926_defconfig' to 'integrator_defconfig', that might also be a step towards eliminating the issue where BR2_TARGET_UBOOT_BOARDNAME must be manually changed to avoid U-Boot build failure since U-Boot recognizes 'integratorcp' but not 'integrator926' (I ran into this U-Boot issue, which is discussed elsewhere in this mailing list).

The kernel built as 'versatile' above now boots until it reaches the end of the init.d/S* startup processing, so QEMU and the kernel are seeing the RFS built by Buildroot.  However, a login prompt does not appear.

If I use that same locally built RFS, but replace the locally built kernel with the pre-built kernel from the QEMU arm-test-0.2.tar.gz, then QEMU boots Linux all the way, including the login prompt.  I can log in an navigate the locally built RFS.

So -- the RFS built by Buildroot is correct, and there must be some final issue in the build of the kernel using 'versatile_defconfig' that prevents the login from running.  I'm pretty close.

I think the Buildroot adoption rate might be higher if there were a documented, streamlined way to build the kernel/RFS and execute it under QEMU, with an end-to-end Buildroot build process triggered by a single 'some_arm_defconfig'.  It might serve as a very useful hardware independent reference platform.

Thanks.

Jim

I think that would be usefull as well.  Building for ARM boards
and then running on Qemu is how I got up to speed on the
Buildroot "environment", but it was harder than it could have
been because the tutorials for buildroot/ARM/Qemu were out of
date and the default configs for the two platforms I tried were
broken (wouldn't build).

Keeping a tutorial up-to-date would take some effort. It might
be easier if it were in a Wiki format that didn't require
wrestling with the bug-tracker and the submissions and approval
of patches.

If the default configs aren't going to be kept up to date, it
would be nice if there was something to indicate which
version(s) of Buildroot they did work with.

It would be easy enough to set up an automated test to check
that all of the default configs build, but checking to see if
they work is obviously a lot harder.

At the appropriate places would do that trick.

But don't ask for that - you'll probably get one of those:
"That requires the purchase of a commercial support contract."
answers since it involves the function of what is actually
produced by the build system, not the build system itself.
