To write this to an SD card, first partition the SD card to have one large ext3, or 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.ext4 /dev/sdc1
mkdir /mnt/sd/
sudo mount /dev/sdc1 /mnt/sd/
sudo tar --numeric-owner -xjf  tsimx6ul_ubuntu_23_04_headless-latest.tar.xz -C /mnt/sd
sudo umount /mnt/sd
sync

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.ext4 /dev/mmcblk2p1
mkdir /mnt/emmc
mount /dev/mmcblk2p1 /mnt/emmc
wget -qO- https://files.embeddedts.com/ts-arm-sbc/ts-7250-v3-linux/distributions/ubuntu/tsimx6ul_ubuntu_23_04_headless-latest.tar.xz | tar --numeric-owner -xJ -C /mnt/emmc/
umount /mnt/emmc
sync
