Not that I know of, yet. I know it's being worked on over in #tegralinux on irc.freenode.net though!

I got arch arm running off a microsd card using the base image on the downloads page, and the kernel + initrd from [ubuntu] modified with a custom (minimalist) init script to load the userspace from the arch base image. It could be easily booted from internal flash as well.

[ubuntu] refers to this post:
[Q&A] Ubuntu on the Transformer (eMMC install)
http://forum.xda-developers.com/showthr ... ?t=1191141

Arch base image:
http://archlinuxarm.org/developers/downloads
ARMv7 OMAP3/4 platforms

My init script (in the root of the initrd):
#!/bin/sh
mkdir -p /proc /sys /dev /run
mount -t proc proc /proc -o nosuid,noexec,nodev
mount -t sysfs sys /sys -o nosuid,noexec,nodev
mount -n -t devtmpfs udev /dev -o mode=0755,size=10M,nosuid
mount -t tmpfs run /run -o nosuid,nodev,mode=755,size=10M
sleep 1
NEWROOT=/new_root
mkdir $NEWROOT
mount /dev/mmcblk1p1 $NEWROOT
exec $NEWROOT/sbin/switch_root $NEWROOT /sbin/init 3

I set up users and passwords by chrooting onto the arch image via busybox.

This of course isn't a complete solution yet, but it's a good starting point. Next we need to copy in all the drivers and try to get more stuff working (wifi, sound, Xorg, etc.) I haven't been able to get my own kernel based on Asus' source to boot the initrd yet.

If anybody is interested in testing or developing this further, I can post instructions to reproduce the boot image and so on. I expect a full official or unofficial port is quite possible :)

Wow, that's awesome - hopefully others with Transformers find this place and help out. I've got my hands full with the HP TouchPad at the moment...

I'm up for helping with this, I've been running Arch on my PC for years and would love to have it on my Transformer instead of Ubuntu!

Provided you bring your own kernel to the party, it's really not much more than what has been said above. Grab one of our armv7h rootfs's to start with, replace the kernel, put it all in the proper place and you should be up and running.

Sweet, I'll give it a try later. Kernel compilation is nothing new to me, I've compiled 3.1 and 3.2 about 30 or 40 times since christmas, first trying to get my OCZ RevoDrive 3 recognized, then trying to add a 3.2 or 3.1 patched kernel to both the Arch and Chakra install images.

Any chance you could provide me with a .config to base it off of? I've never compiled for ARM before and I'd rather not remove needed stuff or forget to include needed stuff.

I haven't looked at it in a while, but now that I see some interest, I'll try to post some more info on what I did soon.

I got it booting using asus' kernel source with a base fs on internal memory or an SD card. I got wifi working, but may need help getting Xorg running.

I modified the .config from android based on options changed by the guys working on ubuntu. You can get the .config from a live system from /proc/config.gz

I'm planning on buying the Transformer Prime. Running dual boot is critical to me (but Ubuntu is.. bleh..), so I plan to investigate this aswell, and will try to help with anything needed when I get mine.

So niel, yes there is interest :-)
