Along rt713

This device uses the pretty popular MID formfactor, like the A710 and A721, but instead comes with an A13 based mainboard.

= Identification =

In android, under Settings->About Tablet, you will find:
 * Model Number: eXagerate XZPAD700
 * Build Number: exg_eb-ita 4.0.4 HML 20121122

= Sunxi support =

Current status
Supported but there are some issues with the touchscreen driver.

Manual build

 * For building u-boot, use the "xzpad700" target.
 * The .fex file can be found in sunxi-boards as xzpad700.fex

Everything else is the same as the manual build howto.

= Tips, Tricks, Caveats =

FEL mode
The VOL+ button triggers FEL mode.

Touchscreen
The ft5x GPL touchscreen driver has some sort of basic functionality but insufficient to be of any real use. The with a little help the best I was able to achieve was just Y-axis inversion while the rest seemed to work right.

Device disassembly
There are 4 screws which need to be removed first. 2 on the connector side and 2 on the opposite side. Use your plastic tool to carefully release all the clips by pushing the back cover inwards. Go over all 4 sides. When opening up the device, be careful as the speaker is attached to the rear cover.

Locating the UART
Although the fex file has evidence that at some time pins PG3 (pin 152) and PG4 *pin 151) were used for an UART port, this may date back to prototyping and may have been physically removed from the production units as I was unable to track down any test pads physically connected to these pins. In the process of attempting to track these test pads I blew a USB serial adapter cable because of the high voltages (up to 24V) present on some test pads so be warned that if you want to double check whether I missed something you should keep clear from the following test pads: TP36, TP73, TP74, TP76.

If you really need to have a serial console to this device while still using the uSD this is how I suggest you you go about it: Where TX and RX are referred to the rt713 side.
 * 1) take off the CSI camera sensor
 * 2) disable csi from the fex
 * 3) remap uart to use pins PE11 (RX) and PE10 (TX)
 * 4) connect the uart to the CSI flext cale connector pins 12 (RX) and 14 (TX)

Have a look at the UART howto for more details on hooking op a serial console.

I've not yet checked this out, put I was able to determine that pins 12 and 14 on the CSI camera sensor connector are physically wired to pins 125 and 124. Here's a link to the fex I'm trying to cook up for this purpose: rt713_remap_csi2uart.fex

If you actually solder the uart to a spare flect cable, open up the device without leaving evidence of you doing that and keep the original script.bin I think it would not void your warranty!
