The PCB has the following silkscreened on it: AVM STV301 MB V1.1 2012.07.16

In android, under Settings->About Tablet, you will find:
 * Model Number: 
 * Build Number: 

= Sunxi support =

Current status
Patch submitted. (2015-02-25)

Manual build

 * For building u-boot, use the jesurun_q5_defconfig target.
 * The .fex file can be found in sunxi-boards as sys_config/a10/jesurun-q5.fex

Everything else is the same as the manual build howto.

Mainline U-Boot
For building mainline u-boot, use the jesurun_q5_defconfig target.

Mainline kernel
Use the sun4i-a10-jesurun-q5.dts device-tree file for the mainline kernel.

NOTE: submitting patch is WIP (2015-02-26)

= Tips, Tricks, Caveats =

Known problem: Hotplug detection does not work
Workaround: sunxi# setenv video-mode sunxi:1280x720-24@60,hpd=0 sunxi# saveenv
 * Manually set video mode and disable hot-plug detection
 * Make env variable persistent:

Verify: Check video-mode env variable: sunxi# printenv video-mode video-mode=sunxi:1280x720-24@60,hpd=0

FEL mode
The button triggers  FEL mode.

= Adding a serial port (voids warranty) =



The UART is easy to spot on the mainboard and by soldering a header on the board it can be used very easily. The default serial settings are 115200,8N1.

Device disassembly
This casing is trivially disassembled by removing 4 Philips screws on the bottom.

Locating the UART
The UART pads are located on the top of, as shown in the picture. You need have some soldering skills to be able to put in a header. More information is available in the UART howto.
