DART-MX8M - 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 stretch-4.14.78-mx8m-v1.0.img.gz from Variscite's FTP server: ftp://customerv:Variscite1@ftp.variscite.com/DART-MX8M/Software/debian/

Note: Some web browsers have removed FTP support. Please see our FTP wiki page.

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 mx8m-dart-debian-recovery-sd.vXX.img.gz
$ sudo umount /dev/sdX*
$ sudo dd if=mx8m-dart-debian-recovery-sd.vXX.img of=/dev/sdX bs=1M conv=fsync status=progress; 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
$ install_debian.sh	- Flash Debian into eMMC
