= Identification =

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


 * Model Number: SoftwinerEvb
 * Build Number: homelet_sugar 4.2.2 JDQ39 xxxxx test-keys

= Sunxi support =

Current status
What works:
 * Serial port
 * MMC
 * Ethernet (using the GMAC driver and in MII mode - needs patches)

What don't work (yet):
 * Wifi (Broadcom ap6330)
 * HDMI

Better results should be achieved by working through the full manual build howto.

Manual build

 * For building u-boot, use the "" target.
 * The .fex file can be found in sunxi-boards as MANUFACTURER_DEVICE.fex

Everything else is the same as the manual build howto.

= Tips, Tricks, Caveats =

FEL mode
The push button on the rearside of the board triggers FEL mode.

JTAG
There are some JTAG pads right next to the UART pads. Here is the pin-out:
 * TP3: JTAG-MS
 * TP4: JTAG-CK
 * TP5: JTAG-DO
 * TP6： JTAG-DI

= Adding a serial port (voids warranty) =



Device disassembly
Only clips attach the top of the case to the rest of it. Insert your plastic tool along the top edge, and gently push the outside rim outwards, the clips should soon release.

Locating the UART
There are some clearly visible test pads next to the SoC. All you need to do is attach some wires according to our UART howto.

Pin-out:
 * TP1: UART0-TX
 * TP2: UART0-RX
