- Insert the microSD Card into your computer and observe which device it registers as by typing
ls /dev/sd*. If you are uncertain, remove the microSD Card and the entry should go away. Once you know which device your microSD Card is, follow the instructions below replacing
/dev/sdXwith the name of the microSD Card in your system.
- Begin partitioning the microSD Card by typing
- Initialize a new partition table by selecting o, then verify the partition table is empty by selecting p.
- Create a new partition by selecting n for ‘new’, then p for ‘primary’, and 1 to specify the first partition. Press enter to accept the default first sector of 2048 then press enter again to select the default last sector.
- Commit the changes by selecting w to ‘write’ the partition table and exit fdisk.
- Format the partition as ext4 by typing
- Install u-boot to the microSD Card (select single, dual, or quad core as appropriate)
wget http://s3.armhf.com/dist/wand/wand-uboot.tar.xz tar xJvf wand-uboot.tar.xz dd if=wand-uboot/wand-uboot-[solo|dual|quad].imx of=/dev/sdX bs=512 seek=2 sync
- Install the desired root filesystem to the microSD Card (ubuntu trusty in this example)
wget http://s3.armhf.com/dist/wand/ubuntu-trusty-14.04-rootfs-188.8.131.52-wand-armhf.com.tar.xz mkdir rootfs mount /dev/sdX1 rootfs tar xJvf ubuntu-trusty-14.04-rootfs-184.108.40.206-wand-armhf.com.tar.xz -C rootfs umount rootfs
- The microSD Card is now ready to boot. Install the microSD Card in the Wandboard module (not the carrier board) and boot. Note that for ubuntu installations, the login userid is ubuntu and the password is ubuntu. Likewise for debian installations, the login userid is debian and the password is debian.

apt-get update after boot to update the package cache, then run
apt-get upgrade to ensure the latest updates are installed.
