As an easy and fast way to recover the VAR-SOM-MX6 NAND flash, Variscite provides a recovery SD card image that can be used to install the pre-built U-Boot, Linux kernel and the UBI file system. This SD card image includes a script (nand-recovery.sh) that installs all the boot images and root file-system.

- Plug-in supplied SD card to your Linux machine, run dmesg and see which device is added (i.e. /dev/sdX or /dev/mmcblk0)
