Introduction
The purpose of this document is to provide a practical introduction on
developing software for the AMOS-820 (Bare board: VAB-820 Freescale i.MX6
Quad) on a Yocto Project development host.
1.1. Overview
AMOS-820 HMI SP v2.0 is developed based on fsl-yocto-3.10.17_1.0.0 (Yocto
1.5 Dora) and enables hardware features defined in VAB-820.
There are four major boot components for Linux, the “

This chapter will guide you through setting up your developing environment.
All the instructions in this guide are for Ubuntu 12.04 (32 Bit or 64 Bit). Please
have the Ubuntu installed in your PC/NB in advance.
To get the Yocto Project expected behavior in a Linux Host Machine, the
packages and utilities described below must be installed. An important
consideration is hard disk space required in the host machine. The
recommended space is 120 GB at least.
2.1. Configure Ubuntu
2.1.1. Install the Host Packages
The following packages are installed to support Yocto development
environment and presented in a bash script that can be cut and pasted into
your environment for execution:
#/bin/bash
# Install LTIB dependant packages
sudo apt-get install wget git-core unzip texinfo libsdl1.2-dev gawk

3.1 Extract VAB-820 BSP
Do not use the root mode to unpack the BSP package on the terminal. It may
cause a failure to build due to the file permission has been affected.
$ tar xvf yocto-vab820-bsp-v2.x.x.tar.bz2
3.2 Machine configurations
The via-setup-release.sh script integrates the VIA release layer into the Yocto
Project build by inserting the layer into the <build dir>/conf/bblayers.conf file.
This setup script has the following optional parameters:
• -b: sets the build directory.
-b <build dir >
$ cd via-release-bsp

VAB-820 supports two booting ways. One is from Micro SD storage card and
the other is SPI ROM. This section will guide you through making the Linux
system boot media for VAB-820.
You can use the image that you built from BSP, the previous Section 3.3
mentioned where it locates, or use the demo image in EVK/
EVK/ EVK/
EVK/ folder of AMOS-
820 HMI Solution Pack.
4.1 Making a SD card image
The Micro SD card image provides the full system to boot with U-Boot and
kernel.
One thing should be taken care before making Micro SD card image:
If there is any mounted partition in Micro SD card, it should be unmounted
first. Then, to flash a SD card image, run the following command:
$ umount /dev/sd<partition>
$ sudo dd if=via-image-x11-imx6qvab820.sdcard of=/dev/sd<partition>
bs=1M && sync
4.1.1 Setup U-boot parameters for Micro SD card
Setup the U-boot parameter at the first time we boot from Micro SD card. Set
the J11 jumper setting (refer to Table 2) to make it bootable from Micro SD.

To check the parameter in U-boot:
VAB-820 U-Boot > pri
bootcmd=run bootcmd_auto
...
The default parameter shows that it loads kernel by detecting the Micro SD
card. If the Micro SD card has been inserted, it loads kernel from Micro SD
card. If not, it loads kernel from eMMC.
You have to set the parameters like the example below. Then the VAB-820
will load kernel from Micro SD card.
VAB-820 U-Boot > setenv bootcmd 'run bootcmd_sd'
VAB-820 U-Boot > saveenv
VAB-820 U-Boot > boot
Or you have to set the parameters like the example below. Then the VAB-820
will load kernel from eMMC.
VAB-820 U-Boot > setenv bootcmd 'run bootcmd_mmc'
VAB-820 U-Boot > saveenv
VAB-820 U-Boot > boot
4.2 Making a Linux System eMMC
VAB-820 does not support booting from eMMC by default. If you want to
make a Linux system on eMMC, there is only one choice to put U-boot on SPI
ROM, and put kernel and rootfs on eMMC.
4.2.1 Requirements
• A Linux System Micro SD storage card made in Section 4.1.
• A mass storage includes: “

”. You can put those files in a USB pen or SD
storage card.
4.2.2 Procedure
User must first boot from Micro SD card on VAB-820 and follow the steps to
make Linux system on eMMC.

4.2.4 Burn u-boot.imx into SPI ROM
Run “ls /dev/mtdblock*
/mtdblock*/mtdblock*
/mtdblock*” to check the SPI ROM device, which is identified as
“
““
“/dev/mtdblock0
/dev/mtdblock0/dev/mtdblock0
/dev/mtdblock0”
””
”.
$ ls /dev/mtdblock*
/dev/mtdblock0
Run the following command to burn u-boot.imx into SPI ROM.
$ sudo dd if=u-boot.imx of=/dev/mtdblock0 bs=512 seek=2
The previous U-boot parameters will be stored in SPI ROM. If you want to
clear the U-boot parameters to default, use the following command:
$ sudo dd if=/dev/zero of=/dev/mtdblock0 bs=512 seek=1536 count=16
4.2.5 Copy images to eMMC
One thing should be taken care before copying images to eMMC: if there is
any mounted partition in eMMC, it should be unmounted first.
Then, run the following command to burn the image into eMMC.
$ sudo dd if=via-image-x11-imx6qvab820.sdcard of=/dev/mmcblk0 bs=1M
4.2.6 Setup U-boot parameters for SPI ROM
Setup the U-boot parameter at the first time we boot from SPI ROM. Set the
J11 jumper setting (refer to Table 3) to make it bootable from SPI ROM.

The default parameter shows that it loads kernel by detecting the Micro SD
card. If the Micro SD card has been inserted, it loads kernel from Micro SD
card. If not, it loads kernel from eMMC.
You have to set the parameters like the example below. Then the VAB-820
will load kernel from Micro SD card.
VAB-820 U-Boot > setenv bootcmd 'run bootcmd_sd'
VAB-820 U-Boot > saveenv
VAB-820 U-Boot > boot

USB LAN module AXI88772
This section illustrates how to setup AXIS USB LAN module AXI88772 on
VAB-820.
First, a driver is required. You can get a pre-build driver, named asix.ko at
EVK\asix folder of BSP, and place it into VAB-820 filesystem. For example:
root@imx6qvab820:~# ls
asix.ko
After that, load the driver by insmod command.
root@imx6qvab820:~# insmod asix.ko
usbcore: registered new interface driver asix
If the driver has been loaded properly with module plugged in, dmesg shows
as follow:
root@imx6qvab820:~# dmesg
