imx6qvab820.sdcard image allows the board to run entirely from the
Micro SD card.
The first step is to copy this image onto a Micro SD card. Insert a card into your Linux host
machine and make sure it is not mounted. Copy the image onto the Micro SD card with the
command below, replacing <device name> with the correct value for the card, for
example “sdb”.

Important: Make sure you are writing to the correct device or the host system environment
could be damaged.
$ sudo dd if=via-image-gui-imx6qvab820.sdcard of=/dev/<device name> bs=1M conv=fsync
Next, on the VAB-820, set the J11 boot select jumper to the Micro SD position shown
below.

Insert the prepared Micro SD card into the VAB-820, connect an HDMI display, and power
on the device to initiate the boot process.
When the boot process is completed, you will see the OpenEmbedded desktop.
