Not sure if this helps anyone, but I thought I'd post it so I at least
have the instructions somewhere the next time I need to do this myself.
I successfully created a normal image file which can be written to a SD
card from Windows or OSX as follows:
1. Install VirtualBox on Windows/OSX and create a new virtual machine
which you install Ubuntu 14.04 in.
2. Follow the following to create an image file
This is for a Wandboard Dual, you need to use different distribution
tar.gz file and different u-boot imx file for other platforms.
It's probably possible to make a smaller image and then resize the
partition afterwards.
Code:
--------------------
# The following instructions was taken from:
https://wiki.archlinux.org/index.php/Creating_Arch_Linux_disk_image
# Make sure we have at least 16GB free space in /media/somedir
# Install kpartx
sudo apt-get install kpartx
# Create an empty image file (using 16 GB didn't work because my SD card was
slightly smaller than 16GB)
sudo fallocate -l 15G /media/somedir/archlinux.img
# Create a partition in the image file and make it bootable
sudo fdisk /media/somedir/archlinux.img
1. o: Create an empty DOS partition table
2. n, p, 1, 8192: Create a primary particion starting at block 8192
3. a, 1: Make primary partition bootable
4. w: Write table to disk
# Mount image as /dev/loop0
sudo losetup -f --show /media/somedir/archlinux.img
sudo kpartx -a /dev/loop0
# Format primary partition in the mounted image
sudo mkfs.ext4 /dev/mapper/loop0p1
# Mount first partition in /media/somedir/tmp
sudo mkdir /media/somedir/tmp
sudo mount /dev/mapper/loop0p1 /media/somedir/tmp
# Retrieve and extract Arch distribution in the mounted directory
wget http://archlinuxarm.org/os/ArchLinuxARM-wand-latest.tar.gz
tar -xf ArchLinuxARM-wand-latest.tar.gz -C /media/somedir/tmp
sudo sync
sudo umount /media/somedir/tmp
# Retrieve and write u-boot to the image
wget http://archlinuxarm.org/os/imx6/boot/wandboard/u-boot-dual.imx
sudo dd if=u-boot-dual.imx of=/dev/loop0 bs=512 seek=2
sudo sync
# Unmount image
sudo kpartx -d /dev/loop0
sudo losetup -d /dev/loop0
# We now have a normal image file in /media/somedir/archlinux.img which we
can copy to the OSX/Windows computer and write to a SD card in the normal way.
--------------------
3. Write archlinux.img to your SD card using your normal Windows/OSX
computer.
4. Insert SD card in Wandboard and let it boot and login via ssh with
root/root and run following receive updates to the U-Boot bootloader:
pacman -Sy uboot-wandboard-dual
5. Follow SqueezeOnArch installation instructions according to the
README.md file:
https://github.com/SqueezeOnArch/soa-aur/blob/master/README.md
The whole process would be a lot easier for Windows/OSX user if step 1
and 2 in the above instruction could be made once by someone and then
redistributed. However, I'm not sure if it was this kind of distribution
of complete images that brought the CommunitySqueeze project down, so I
don't want to do it myself until someone with deeper knowledge has
ensured me there isn't some kind of legal problem to distribute complete
images which I haven't realised yet.
