2. Image Installation
The AMOS-825 Android system only provides booting from the SPI ROM with an eMMC.
This section explains the setup requirements for booting from the SPI ROM with an eMMC.
A precompiled image is provided in the “Firmware” folder of the EVK.
Booting from the SPI ROM with an eMMC 2.1.
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 AMOS-825, set the Micro SD/SPI boot switch to the Micro SD position shown
below.

Insert the prepared Micro SD card into the AMOS-825, connect an LVDS display, and
power on the AMOS-825 to initiate the boot process. When the boot process is completed,
you will see the command line of Linux environment.

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 Micro SD/SPI boot switch 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.

3. Hardware Functions
Setting Up U-Boot Parameters 3.1.
The first step is to connect the host machine and the AMOS-825 through the COM port.
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.

Next, power on the AMOS-825 system 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.

Debug console view of boot process
To list the current U-Boot parameters, use the following command:
=> printenv
Make sure the printout message is as follows:
=> printenv
baudrate=115200
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
Restoring Default U-Boot Parameters 3.2.
If the U-Boot parameters have been modified, the “destroyenv” command in the U-Boot
console can restore the factory default settings. To restart the device, use the “reset”
command.
=> destroyenv
=> saveenv
=> reset
Using the Android Console 3.3.
The first step is to connect the host machine and the AMOS-825 through the COM port.
Use a serial port communication program such as PuTTY, GtkTerm, or Minicom, to 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. Next, power on the AMOS-825 to initiate the boot process.
When the boot process is completed, you will automatically log in to an Android console.
