TS-4900 Yocto getting started
Yocto itself is a set of scripts and tools used to build a custom Distribution. In our default images we try to include all of the common utilities requested by users so rebuilding Yocto should not be necessary in many cases. Once installed the default user is "root" with no password.
Our Yocto rootfs is available here:

To write this to an SD card, first partition the SD card to have one large ext4 partition. See the guide here for more information. Once it is formatted, extract this tar with:
# Assuming your SD card is /dev/sdc with one partition
mkfs.ext4 /dev/sdc1
mkdir /mnt/sd/
sudo mount /dev/sdc1 /mnt/sd/
sudo tar -jxf ts-x11-image-tsimx6-latest.rootfs.tar.bz2 -C /mnt/sd
sudo umount /mnt/sd
sync
To rewrite the eMMC, boot to the SD card. You cannot rewrite the emmc while it is mounted elsewhere, or used to currently boot the system. Once booted to the SD, run:
mkfs.ext4 /dev/mmcblk2p1
mkdir /mnt/emmc
mount /dev/mmcblk2p1 /mnt/emmc
wget -qO- ftp://ftp.embeddedarm.com/ts-socket-macrocontrollers/ts-4900-linux/distributions/yocto/fido/ts-x11-image-tsimx6-latest.tar.bz2 | tar xj -C /mnt/emmc/
umount /mnt/emmc
sync
The same commands can be used to write SATA by substituting /dev/mmcblk2p1 with /dev/sda1.
