2. Image Development
This section explains the setup requirements for booting from the SPI ROM with an eMMC.
A precompiled image is provided in the “EVK” folder of the BSP.
2.1. Booting from the SPI ROM with an eMMC
The Images_autoinstall_sd.zip includes the Android EVK system image and the installation
scripts files.
The first step is to extract Images_autoinstall_sd.zip file to make the bootable Micro SD
card. Insert a card into your Linux host machine and make sure it is not mounted. Open the
terminal on your host machine, and run the script mk_install_sd.sh as shown 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 ./mk_install_sd.sh /dev/<device name>
Next, on the VAB-820, set the boot select jumper (J11) to the Micro SD position as shown
below.

Insert the prepared Micro SD card into the VAB-820, connect an HDMI display, and power
on the VAB-820 to initiate the boot process. When the boot process is completed, you
will see the Linux environment command line.
To install the U-Boot and Android EVK image into SPI ROM and eMMC, use the following
command:
$ ./fsl-eMMC-partition.sh –f imx6q /dev/mmcblk0

In order to boot from the SPI ROM make sure the boot select jumper (J11) is set to SPI
ROM boot.

Next, power on the device to initiate the boot process. When the boot process is
completed, you will see the Android desktop.

2.2. Setting Up U-Boot Parameters
The first step is to connect the host machine and the VAB-820 through the COM2
connector (J5). Use a serial port communication program such as PuTTY, GtkTerm, or
Minicom, to configure the serial port setting and connect to the debug console. There you
will be able to see the U-Boot boot log and adjust settings in the U-Boot console.
+--------------------------------------------------------------+
| A - Serial Device : /dev/ttymxc0 |
| B - Lockfile Location : /var/lock |
| C - Callin Program : |
| D - Callout Program : |
| E - Bps/Par/Bits : 115200 8N1 |
| F - Hardware Flow Control : No |
| G - Software Flow Control : No |
+--------------------------------------------------------------+

Next, power on the VAB-820 to initiate the boot process. When prompted, press any key
to stop the boot process, and enter the U-Boot console as illustrated by the screenshot
below.

To list the current U-Boot parameters, use the following command:
=> printenv
Make sure the printout message is as follows:
=> printenv

boot_emmc_root=mmc dev ${root_media_uboot};ext2load mmc ${root_media_uboot}:${root_partition} ${loadaddr}
uImage;ext2load mmc ${root_media_uboot}:${root_partition} ${dtbaddr} imx6q-vab820.dtb;bootm ${loadaddr} - ${dtbaddr};
boot_media=booti mmc1
2.3. Restoring Default U-Boot Parameters
If the U-Boot parameters have been modified, the “destroyenv” command in the U-Boot
console can restore the factory default settings.
To restore the default U-boot settings, use the following command:
=> destroyenv
=> saveenv
=> reset
