This video shows the first 3 fresh GTA04A3 boards and how they are tested.
The test equipment consists of some old MacMini (PowerPC based)
with USB cable, a SD card with the hardware-validation Linux kernel
and a battery.
Testing starts by inserting the SD card, adding a wire to hold the battery,
connect USB and finally insert the Battery.
Soon after doing this, U-Boot switches on the Power LED to red/yellow/green.
The test software thinks that there is no connection on USB, since the
kernel is still booting and setting up the musb driver and the ethernet
After a while, the first ping to the board becomes successful, and the
detailled tests start. Tests include reading the IMEI from the UMTS
modem module, configuring WLAN and scanning for the MacMini's
WLAN and Bluetooth transmitters.
Finally, almost all tests are passed, except the one for the Camera
module - which is not plugged in.
Please note, that this test is not really complete. Amongst the areas
not tested are: Display, Audio, UMTS transmission, Vibracall, GPS
