Using the Android Console
The first step is to connect the host machine and the VAB-820 through the COM 2
(connector J5). 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 VAB-820 to initiate the
boot process. When the boot process is completed you will be prompted to login.
