Once installed the default user is "root" with no password.
| Note: | This is a shared image that supports the TS-4900, TS-7970, and TS-TPC-7990. |
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.ext3 /dev/sdc1
mkdir /mnt/sd/
sudo mount /dev/sdc1 /mnt/sd/
sudo tar xjf debian-armhf-jessie-latest.tar.bz2 -C /mnt/sd
sudo umount /mnt/sd
sync
| Note: | The ext4 filesystem can be used instead of ext3, but it may require additional options. U-Boot does not support the 64bit addressing added as the default behavior in recent revisions of mkfs.ext4. If using e2fsprogs 1.43 or newer, the options "-O ^64bit,^metadata_csum" must be used with ext4 for proper compatibility. Older versions of e2fsprogs do not need these options passed nor are they needed for ext3. |
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.ext3 /dev/mmcblk2p1
mkdir /mnt/emmc
mount /dev/mmcblk2p1 /mnt/emmc
wget -qO- ftp://ftp.embeddedarm.com/ts-socket-macrocontrollers/ts-4900-linux/distributions/debian/debian-armhf-jessie-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.
