2. Image Devel pment
This secti n explains the setup requirements f r b ting fr m a Micr SD card r the SPI
ROM.
A prec mpiled image is pr vided in the “EVK” f lder f the BSP.
2.1. B ting fr m a Micr SD Card
The via-image-gui-imx6qvab820.sdcard image all ws the system t run entirely fr m the
Micr SD card.
The first step is t c py this image nt a Micr SD card. Insert a Micr SD card int
y ur Linux h st machine and make sure it is n t m unted. C py the SD Card image nt
the Micr SD card with the c mmand bel w, replacing <device name> with the c rrect
value f r the card, f r example “sdb”.
Imp rtant: Make sure y u are writing t the c rrect device r the h st system
envir nment c uld be damaged.
$ sudo dd if=via-image-gui-imx6qvab820.sdcard of=/dev/<device name> bs=1M conv=fsync
Next, set the switch SW2 t the Micr SD p siti n as sh wn bel w.

Insert the prepared Micr SD card int the ARTiGO A820, c nnect an HDMI display, and
p wer n the device t initiate the b t pr cess.
When the b t pr cess is c mpleted, y u will see the OpenEmbedded deskt p.

2.2. B ting fr m the SPI ROM and eMMC
The ARTiGO A820 supp rts b ting fr m the SPI ROM while l ading the kernel and
r t filesystem fr m eMMC.
The first step is t prepare a Micr SD card with the default image acc rding t secti n
2.1. Next, c py the u-b t.imx and via-image-gui-imx6qvab820.sdcard files fr m the BSP
nt a mass st rage device such as a USB thumb drive. Make sure the SW2 switch is set
t Micr SD b t then insert the Micr SD card and the USB thumb drive int the
ARTiGO A820.
T check that the system has c rrectly setup the SPI ROM as an MTD bl ck device, use
the f ll wing c mmand:
$ ls /dev/mtdblock*
/dev/mtdblock0
Please n te that if y u have previ usly saved U-B t parameters, it is rec mmended t
clear that area f the SPI ROM with the f ll wing c mmand:
$ sudo dd if=/dev/zero of=/dev/mtdblock0 bs=512 seek=1536 count=16
Flash the U-B t binary fr m the mass st rage device nt the SPI ROM:
$ sudo dd if=u-boot.imx of=/dev/mtdblock0 bs=512 seek=2
C py the r t filesystem image fr m the mass st rage device nt the eMMC st rage.
$ sudo dd if=via-image-gui-imx6qvab820.sdcard of=/dev/mmcblk0 bs=1M
In rder t b t fr m the SPI ROM make sure the SW2 switch is set t SPI ROM b t.

2.3. Setting Up U-B t Parameters
The first step is t c nnect the h st machine and the ARTiGO A820 thr ugh the nb ard
COM debug p rt. Use a serial p rt c mmunicati n pr gram such as PuTTY, GtkTerm, r
Minic m, t c nfigure serial p rt setting and c nnect t the debug c ns le. There y u
will be able t see the U-B t b t l g and adjust settings in the U-B t c ns le.

T list the current U-B t parameters, use the f ll wing c mmand:
=> printenv
Make sure the print ut message includes “b tcmd=run b tcmd_aut ”.
The default “b tcmd” parameter is set t aut detect the system l cati n by first
attempting t l ad the kernel fr m the Micr SD card. If it is n t detected it c ntinues t
b t fr m the eMMC.
T l ad the kernel fr m the specified device, refer t the tw examples bel w.
T l ad the kernel fr m the Micr SD card, use the f ll wing c mmand:
=> setenv bootcmd 'run bootcmd_sd'
=> saveenv
=> boot
T l ad the kernel fr m the eMMC, use the f ll wing c mmand:
=> setenv bootcmd 'run bootcmd_mmc'
=> saveenv
=> boot
2.4. Rest ring Default U-B t Parameters
If the U-B t parameters have been m dified, the “destr yenv” c mmand in the U-B t
c ns le can rest re the fact ry defaults settings.
T restart the device, use the “reset” c mmand:
=> destroyenv
=> reset

2.5. Using the OpenEmbedded C ns le
The first step is t c nnect the h st machine and the ARTiGO A820 thr ugh the
nb ard COM debug c nnect r. Use a serial p rt c mmunicati n pr gram such as
PuTTY, GtkTerm, r Minic m, t c nnect t the debug c ns le. There y u will be able
t see the U-B t b t l g and adjust settings in the U-B t c ns le. Next, p wer n

3. Build Envir nment Setup
This secti n guides y u thr ugh setting up the build envir nment f r devel pment. All
instructi ns are based n using Ubuntu 12.04 LTS and in newer Ubuntu versi ns.
T make sure that the build pr cess c mpletes successfully, we rec mmend at least
120GB f disk space, and 15GB f c mbined mem ry and swap space n the h st
machine.
3.1. C nfiguring Ubuntu
The f ll wing packages are required f r the Y ct devel pment envir nment. The
required packages can be installed using the bash script bel w:
#/bin/bash
# Install dependant packages
$ sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib build-
essential chrpath socat
$ sudo apt-get install libsdl1.2-dev xterm sed cvs subversion coreutils texi2html docbook-
utils python-pysqlite2 help2man make gcc g++ desktop-file-utils libgl1-mesa-dev libglu1-
mesa-dev mercurial autoconf automake groff curl lzop asciidoc
The t l t create images f r use with the U-B t b t l ader, “mkimage”, is pr vided
by different packages in Ubuntu 12.04 and in newer Ubuntu releases.
On Ubuntu 12.04 install it as bel w.
$ sudo apt-get install uboot-mkimage
On Ubuntu 14.04 and newer versi ns install it as bel w.
$ sudo apt-get install u-boot-tools

4. Image Build
4.1. Extracting the ARTiGO A820 BSP
Use the f ll wing c mmand t extract the c ntents f the BSP.
$ tar xvf A820-yocto-bsp-v3.2.1.tar.bz2
4.2. Machine C nfigurati n
The via-setup-release.sh script creates the build direct ry with the Y ct c nfigurati n
files f r y ur target machine.
This script has the f ll wing pti nal parameter:
• -b: set the name f the build direct ry. F r example “-b build-a820” in the
c mmand bel w.
$ cd a820-yocto-bsp
$ MACHINE=imx6qvab820 source via-setup-release.sh -b build-a820
4.3. Building an SD Card Image
This BSP pr vides the “via-image-gui” Y ct image as default. Use the “bitbake”
c mmand t create an SD Card c mpatible image.
$ a820-yocto-bsp/build-a820$ bitbake via-image-gui
After the c mpilati n, the a820-y ct -bsp/build-a820/tmp/depl y/images/imx6qvab820

5. Hardware Functi ns
5.1. Setting Up COM 1
The ARTiGO A820 COM 1 supp rts b th RS-232 and RS-485 m des. The default m de
is RS-232.
5.1.1. Setting Up RS-232 M de
The first step is t c nnect the h st machine and the ARTiGO A820 thr ugh the COM 1
p rt. Use a serial p rt c mmunicati n pr gram such as PuTTY, GtkTerm, r Minic m, t
c nnect t the COM 1 p rt.
Next, set the COM m de switch t the RS-232 p siti n as sh wn bel w.
