This is the complete, accurate guide to getting a TS-7260 to boot debian etch with a nice large root

Get a 512mb image from technologic, such as 512mbsd-7400-linux26-etch-oabi.dd. has these images.

dd it to disk:

dd if=512mbsd-7400-linux26-etch-oabi.dd of=/dev/mmcblk0

Eject the disk, and re-insert it. If your computer automounts it, umount it. This is to make sure the partition table we're looking at is sane.

With devio, mtd-utils, and jfsutils installed (these may be different for non-ubuntu systems), fire up gparted and resize the partition, click-and-drag style. Uncheck "round to cylinders". If it fails the first time, fsck it, it'll probably be clean, and just try to resize again, it'll work. We use gparted for this because it's the cleanest, easiest way to handle the nonstandard geometry while still making sure that the filesystem is not destroyed.

Boot it on the arm board

Enter ln -sf /linuxrc-sdroot /linuxrc; save to make the arm board boot into the full environment on the sdcard.

reboot the arm board.

log in as root

set a password

set up /etc/network/interfaces:

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static

set up /etc/resolv.conf:


run /etc/init.d/networking restart

run /etc/init.d/ssh restart

disable weird services from starting and shut them off, like apache and x:

update-rc.d -f apache2 remove
update-rc.d -f startx remove
update-rc.d -f x11-common remove

Lenny's not smart enough to mount devpts right, so make /etc/fstab look like this:

proc             /proc         proc    defaults                 0    0
sysfs           /sys            sysfs   default         0 0
none /dev/pts devpts rw 0 0

lenny needs this: set up the system to mount devpts properly by running mount -v -t devpts none /dev/pts. Otherwise, sshing in will fail.
