TS-7180 MicroSD Backup/restore

These instructions describe how to create a bootable SD card image. They assume you have an SD card with one partition. Most SD cards ship this way by default, but if you have modified the partitions, you may need to use a utility such as gparted or fdisk to recreate the table with one partition.

These instructions assume your SD interface is /dev/sdc, but plug the SD card into your USB reader and check dmesg to confirm. On the TS-7180, its on-board SD card reader is /dev/mmcblk1p1.

Running these commands will reflash the SD card to our default latest image.

# Verify nothing else has this mounted
sudo umount /dev/sdc1

sudo mkfs.ext4 -O ^metadata_csum,^64bit /dev/sdc1
sudo mkdir /mnt/sd
sudo mount /dev/sdc1 /mnt/sd/
wget https://ftp.embeddedTS.com/ts-arm-sbc/ts-7180-linux/distributions/debian/ts7180-debian-buster-latest.tar.xz
sudo tar -xjf ts7180-debian-buster-latest.tar.xz -C /mnt/sd
sudo umount /mnt/sd
sync

After it is written you can verify the data was written correctly. Reinsert the disk to verify any block cache is gone, then run these:

mount /dev/sdc1 /mnt/sd
cd /mnt/sd/
sudo md5sum -c md5sums.txt
umount /mnt/sd
sync

The md5sums command will report what differences there are, if any, and return if it passed or failed.
