Overview
The TS-9420 is a production tool used for mass replicating software on the Technologic Systems' ARM and X86 series of Single Board Computers. It can be used in conjunction with the TS-9422 POST Code Display Board in order to provide additional information during programming.
Getting Started
TS-9420-ARM
Using the TS-9420 in conjunction with a TS-72XX series board you can recover from almost any state. While you can use an NFS root with a bad debian filesystem with a board, the TS-9420 will even allow you to boot a system that otherwise has a corrupt redboot. To boot to the TS-9420, most commonly you will want dip switches 1 and 2 down, with the rest up. This will boot to the TS-9420, and set it in ARM mode.

Repairing/Replace the YAFFs image.
The Yaffs filesystem is the filesystem used for the onboard flash on the TS-7250 and TS-7260.
You have to erase the filesystem completely (either with rm -rf or eraseall /dev/mtd/1) and extract your new image onto the mounted filesystem. This way, YAFFS will auto-discover the bad sectors as you are extracting and work-around them.
Boot to an NFS root filesystem. If you are using kernel ts8 use this as your nfs root filesystem %%% ftp://oz.embeddedx86.com/images/debian256/debian256-5-6-2005.tar.gz %%% if you are using kernel ts9 use this as your nfs root filesystem ftp://oz.embeddedx86.com/images/debian256/debian256-10-27-2005.tar
Refer to the TS-ARM developers manual(http://www.embeddedarm.com/Manuals/TSARML.PDF) for information on how to boot to an NFS root filesystem.
Erase the second partition of your onboard flash(use the char device not the block device).
eraseall /dev/mtd/1
Mount the second partition of your onboard flash and extract the new filesystem. mount /dev/mtdblock/1 /mnt; tar xzvf /path/to/7250rootfs.tar.gz -C /mnt
Unmount the second partition of your onboard flash and reboot. umount /mnt
shutdown -r now
