TS-4900 Jessie Getting started

From Technologic Systems Manuals

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 prepare an SD card, use partitioning tools such as 'fdisk' 'cfdisk' or 'gparted' in linux to create a single linux partition on the SD card. Once the partition is set up and formatted, extract the above tarball 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 --numeric-owner -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 the unit must be booted to SD or any other media that is not eMMC. Once booted, run the following commands.:

mkfs.ext3 /dev/mmcblk2p1
mkdir /mnt/emmc
mount /dev/mmcblk2p1 /mnt/emmc
wget -qO- https://files.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 a SATA drive by substituting /dev/mmcblk2p1 with /dev/sda1.
