Product OverviewProduct Overview
Product Overview
Based on the ultra compact Pico-ITX form factor, measuring 10 cm x 7.2 cm,
the VIA VAB-800 is the first VIA Pico-ITX board to feature an ARM SoC. With
the choice of either an 800MHz or 1GHz Freescale Cortex-A8 ARM SoC, the
VIA VAB-800 combines two integrated GPUs for dual displays and 3D/2D
graphics acceleration to provide full HD playback support for resolutions up
to 1080p.
The ultra compact VIA VAB-800 Pico-ITX is optimized for both performance
and power to meet the high end demands of advanced industrial and in-
vehicle applications, boasting a ruggedized design with a wide operating
temperature range from -20 to 70°C, while offering extremely low power
consumption of a maximum 5W TDP. In addition to the ruggedized design VIA
offers up to 7 years longevity support.
The VIA VAB-800 provides an impressive selection of rear I/O in a compact
form factor including VGA and Mini HDMI ports, two USB 2.0 ports and one
Ethernet port. Customers can take advantage of VIA’s industry leading
hardware and software support to create customized designs with a quick time
to market. The VIA VAB-800 is also available with board support packages
(BSP) for the Android and Embedded Linux 2.6 operating systems (BSP for
Windows Embedded Compact 7 is only available through third party).
On board pin headers provide support for an additional of two USB 2.0 ports,
one SATA connectors, two COM pin headers, two single channel LVDS
connectors, one micro SD connector and eight GPIO pin headers, etc.

The VAB-800 can be fitted into any chassis that has the mounting holes
compatible with the standard Pico-ITX mounting hole locations. Additionally,
the chassis must meet the minimum height requirements for specified areas of
the mainboard.

Each side of the mainboard should have a buffer zone from the internal wall
of the chassis. The side of the mainboard that accommodates the I/O coastline
should have a buffer of 1.00 mm. The side on the opposite end of the I/O
coastline should have a buffer of at least 5.00 mm. The two sides adjacent to
the I/O coastline should have at least a 10.00 mm buffer.

Modifications configure files if user would like
to evaluate VAB-800 with Ubuntu
2. Copying the u-boot/uImage/driver modules.
2.1 Insert the Micro SD storage card which the OS has made by
“MCIMX53-START-R-BSP-11-09_C.exe” into your Linux developing PC.
2.2 Umount the Micro SD storage card if Linux OS auto mount your Micro
SD card.
The Micro SD card code name for this example is sdb1.
user@user:~ $ sudo umount /dev/sdb1
The path of EVK for this example is /home/user/EVK

2.4 Copy kernel “uImage” to Micro SD storage card
user@user:~/EVK$ sudo dd if=uImage of=/dev/sdb bs=512 seek=2048
2.5 Add driver modules of VAB-800
user@user:~/EVK$ sudo mount /dev/sdb1 /mnt
user@user:~/EVK$ sudo mkdir /mnt/mountpoint
user@user:~/EVK$ sudo cp ./modules.tar.bz2 /mnt/mountpoint/lib
user@user:~/EVK$ cd /mnt/mountpoint/lib
user@user:/mnt/mountpoint/lib$ sudo tar jxvf modules.tar.bz2
2.6 Put modification files in root file system
The configuration files should be modified for VAB-800. User can use files
“vab-800_rootfs_patch.tar.bz2” in EVK folder.
■ Unzip vab-800_rootfs_patch.tar.bz2
user@user:~/EVK$ sudo tar jxvf vab-800_rootfs_patch.tar.bz2
User will get the following files as shown below:
■ User runs the script “vab-800.sh” to copy modification files automatically.
user@user:~/EVK$ sudo ./vab-800.sh /mnt/mountpoint
user@user:~/EVK$ sudo sync && sync
user@user:~/EVK$ sudo umount /mnt
Now, unplug Micro SD storage card from your computer.

[VGA]
[VGA][VGA]
[VGA]
To set VGA as display output
setenv bootargs_base ‘setenv bootargs console=ttymxc1,115200

To set VGA resolution
setenv vga 'setenv bootargs console=ttymxc1,115200
video=mxcdi1fb:GBR24,VGA-XGA di1_primary vga'
To replace the resolution, change the red color part with the desire resolution
mode.
For example: To set 1680 x 1050 resolution, change VGA-XGA with VGA-
WSXGA+:
setenv vga 'setenv bootargs console=ttymxc1,115200
video=mxcdi1fb:GBR24,VGA-WSXGA+ di1_primary vga'
There are four modes to be set in VAB-800:
VGA-WSXGA+ : 1680x1050p-60
VGA-SXGA : 1280x1024p-60
VGA-XGA : 1024x768p-60
VGA-SVGA : 800x600p-60

For example: To set 1920x1080, change 1024x768 with 1920x1080:
setenv hdmi ‘setenv bootargs console=ttymxc1,115200
video=mxcdi0fb:RGB24,1920x1080M@60 hdmi di0_primary’

3. Setting booting storage devices
Here, user can set the boot device as either Micro SD or eMMC.
Set boot device as Micro SD:
setenv bootcmd ‘run bootcmd_mmc; bootm ${loadaddr}’
Set boot device as eMMC:
setenv bootcmd ‘run bootcmd_emmc; bootm ${loadaddr}’
4. Setting MAC address
Here, user can set the MAC address in u-boot. The address is on the Ethernet
physical port.
setenv ethaddr xx:xx:xx:xx:xx:xx
It is a must to reset after you set MAC address and save already:
saveenv
reset

4.5. Making demo image to eMMC (optional)
This section will guide user to copy images to eMMC for evaluation. However,
it is a must to finish first the section 4.2~4.3 before applying this section.
To make a demo image compression file, follow the steps below:
1. Getting u-boot, and kernel image.
User can directly get the u-boot.bin, and uImage from EVK folder.

Binary Description
uuuu----boot.bin
boot.binboot.bin
boot.bin U-Boot bootloader Image
uImage
uImageuImage
uImage Linux Kernel Image
2. Making Ubuntu root file system
2.1 Insert the Micro SD storage card which the OS has made in section 4.3
on your Linux developing PC. (Ubuntu 10.04.x x86 at least)
2.2 Compress Micro SD storage card as a compression file.
The Micro SD card code name for this example is sdb1.
user@user:~ $ sudo mount /dev/sdb1 /mnt/mountpoint
user@user:~ $ cd /mnt/mountpoint
user@user: /mnt/mountpoint$ sudo tar jcvf ~/EVK/rootfs.tar.bz2 ./*
...
user@user: /mnt/mountpoint$ sudo sync && sync
user@user: /mnt/mountpoint$ cd ~
user@user:~ $ sudo umount /mnt/mountpoint
It would take 30~40 min to generate a “rootfs.tar.bz2”. User can uncompress it
into eMMC, and get an Ubuntu demo image.
3. Make demo image boot from eMMC.
