3 Inspection& SW Upgrade

3.1 The inspection of PCBA

Function inspection

„ Firstly check whether the external equipment is connected properly, then power on, if the battery is

inserted, the red light will be flash.

„ Check LCD display, speaker and MIC sound quality, BT link, press the relevant key to test all functions

one by one.



4 SW upgrade, use the PhoenixSuit which ALLWINNER special single-machine upgrade tool。

„ Open the Software in Computer as below picture:

„ Click“一键刷机”，the click“浏览”to select the software path.

„ Press and hold the UBOOT key to make sure the V831 development board enters SW upgrade mode,

and then connect the USB cable from Computer to the V831 development board, If the connection

is OK, the software automatically enters the SW upgrade window as below display, and click “YES”

to go ahead the SW download until finish.
