VAR-SOM-MX6 - Yocto/Android recovery SD card general
Variscite provides a recovery SD card image that can be used to install the pre-built Yocto or Andorid images into the internal storage device/s of the SOM.
Download the recovery SD card image
Download mx6-som-recovery-sd.vXX.img.gz (latest) from Variscite's FTP server: ftp://customerv:Variscite1@ftp.variscite.com/VAR-SOM-MX6/Software/
Write the image to an SD card
During the SD card image writing all files and partitions are erased from target device.
Double check that the device is correct to avoid accidentally overwriting a different device and potentially damage your existing operating system

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 mx6-som-recovery-sd.vXX.img.gz $ sudo umount /dev/sdX* $ sudo dd if=mx6-som-recovery-sd.vXX.img of=/dev/sdX bs=1M (Replace /dev/sdX with your actual device)
Using a Windows based host
- Download Win32 Disk Imager from: https://sourceforge.net/projects/win32diskimager/ and install it.
- Extract downloaded <image name>.img.gz file to get <image name>.img (using 7-Zip for example)
- Insert your SD card into your PC.
No need to format the SD card before writing the image to it, as the card will be formatted once it will be flashed. - Run the file named Win32DiskImager.exe (in Windows 7,8 and 10 we recommend that you right-click this file and choose “Run as administrator”).
- If the SD card (Device) you are using isn’t found automatically. Click on the drop down box and select it
- In the Image File box, choose the <image name>.img file you have extracted previously
- Click Write
- After a few minutes, you receive a notification that your SD has been created successfully.
Using a Mac OS/X host
You can use the OSX DD Tool to flash .img files onto your SD card
