DART-6UL Debian Recovery SD card

Variscite provides a recovery SD card image that can be used to install the pre-built Debian images into the internal storage device of the SOM.

Download the recovery SD card image

Download var-mx6ul-debian-recovery-sd.vXX.img.gz (latest) from Variscite's FTP server: sftp://customerv@ftp.variscite.com/Public/DART-6UL/Software/debian/

For more information about Variscite's FTP server, see: https://variwiki.com/index.php?title=FTP

See the detailed changelog

Write the image to an SD card

Using a Linux based host

Plug-in the SD card to your Linux HOST PC, run dmesg and see which device is added (i.e. /dev/sdX or /dev/mmcblkX)

$ gunzip var-mx6ul-debian-recovery-sd.vXX.img.gz
$ sudo umount /dev/sdX*
$ sudo dd if=var-mx6ul-debian-recovery-sd.vXX.img of=/dev/sdX bs=1M; sync

(Replace /dev/sdX with your actual device)

Using a Windows based host

Download Win32 Disk Imager from: https://sourceforge.net/projects/win32diskimager/, install and run it.
Select the image file, and the SD card device - double check that the device is correct to avoid accidentally overwriting a different device.
Click on "Write".
No need to format the SD card before writing the image to it.

Recover NAND flash/eMMC

Power-off the board.
Insert the SD card into the SD card slot of the carrier board (DVK)
Make sure the Boot DIP switches are set to SD card: Setting the Boot Mode
Power up the board - it will boot into Linux from the SD card

Flash from command line

Login as root (password root)
From Linux command line, type the following

# debian-nand.sh - Flash Debian into NAND flash (for SOMs with NAND flash)

In case you are using a SOM with eMMC, run the following command as root to install Debian on it:

# debian-emmc.sh - Flash Debian into eMMC (for SOMs with eMMC)
