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.
