2.1.
Booting from a Micro SD Card
The via-image-gui-imx6qvab820.sdcard image allows the system to run entirely from the
Micro SD card.
The first step is to copy this image onto a Micro SD card. Insert a Micro SD card into
your Linux host machine and make sure it is not mounted. Copy the SD Card 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, set the switch SW2 to the Micro SD position as shown below.

Insert the prepared Micro SD card into the ARTiGO A820, connect an HDMI display, and
power on the device to initiate the boot process.
