TZX-Q8-713B7

= Identification =

In android, under Settings->About Tablet, you will find:


 * Model Number: SoftwinnerEvb
 * Build Number: 713B7.B1.50.TZX.R01.eng.0121

The PCB shows: TZX-Q8-713B7

= Sunxi support =

Current status
U-Boot properly supports the device.

Some features are missing on Linux (sunxi-3.4 branch):
 * Touchscreen support is not there but external patches are available
 * Accelerometer support is not there but external patches are available

Manual build

 * For building u-boot, use the "TZX-Q8-713B7" target.
 * The .fex file can be found in sunxi-boards as tzx-q8-713b7.fex

Everything else is the same as the manual build howto.

= Tips, Tricks, Caveats =

FEL mode
Any button (VOL-, VOL+) triggers FEL mode.

= Adding a serial port (voids warranty) =



The devices uses UART1 for U-Boot and Linux messages: make sure to properly set console=ttyS1 and spawn getty on ttyS1.

Device disassembly
See the Q8 tablet format disassembly page.

Locating the UART
Uart has 2 pads on the back of the PCB (near the SoC). On the A13, UART1 is on pins 151 and 152, which are left of the SoC. Just solder on some wires according to the UART howto
