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 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 x.img.gz file to get x.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 

Double check that the device is correct to avoid accidentally overwriting a different device.

• In the Image File box, choose the x.img file you have extracted previously 
• Click Write 
• After a few minutes, you receive a notification that your SD has been created successfully.
