Use Busybox or Buildroot if you are creating from scratch. See
"Prepare minimal RootFS" sub-section on
http://wiki.embeddednirvana.org/ARM_Emulation_Using_QEMU for a very
crude and proof-of-concept stuff for building a rootfs.

You may use http://narcissus.angstrom-distribution.org/ for your
target too. It creates Angstrom rootfs for your device.

Probably OT.

Does anyone know where/how to get prebuilt kernel images ? Had downloaded an image from Narcissus for use on QEMU. It has the kernel modules and other packages, but not the zImage*.bin file.

Also, anyone here using Poky / Yocto / Linaro ?

[Suchakra]

I have used Poky before with qemu. Check the manual on their site for details. It works well and uses its own qemu based emulator. Also, prebuilt kernel images are available for qemu on qemu's site as an 'arm-test' tarball. It contains a kernel for Integrator/CP board and a small filesystem. Haven't used it with the narcissus' rootfs image though.

Thanks Suchakra. That is very helpful.

May I take the liberty of asking the community here 2 more questions --

1. What do people feel about the support ecosystem around specific Linux distros ? In my quest for a lean-n-mean (fat-free) disto I've had some amount of frustration with Angstrom pre-built images (from narcissus), for IGEPv2 (rev.C) boards (OMAP DM3730 1GHz, 512MB/512MB), which doesn't boot with the pre-built images. Am yet to try building an image, might fare better. Questions left on Angstrom list, don't seem to fetch many useful answers ? So wondering if it'd be better to move to another distro where I might get better community support ?

2. Is someone aware of some good independent consultants or small companies, good with board level design ? Guys who can do some extension/modification work on ARM boards/COM's ? I've come accross several who make tall claims, but after having burnt some hard-cash, are yet to deliver anything working. I suspect most of the folks to be guys who can deal with the software, or BSP level at most... at HW level, the skill seems to be really rare.

If aware of someone like that, kindly drop me a mail offlist.

cheers,
Jay
