libv> there seem to be 3 different board versions, but no pictures of any boards are apparently available. I fear that this device will end up being a rebadger of either a A710 or A721.

Different motherboard versions

There were 3 hardware versions (HwvX) released by GoClever. They have a different PCB, camera or g-sensor:

Hardware version Serial numbers Camera module G-sensor (module) Available Android versions (official)
HWv1 GCA731111XXXX GC0308 MMA7660 2.3.4, 4.0.3
HWv2 GCA731201xxxx - GCA731205xxxx SP0838 MXC622X 2.3.4, 4.0.3
HWv3 GCTA731206xxxx GC0308 MXC622X 4.0.4

GCTA731207XXXX is made with the parts that were in stock - there are some components from HWv2. and some from HWv3.

Manual build

  • For building u-boot, use the "MANUFACTURER_DEVICE" 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

Add MANUFACTURER DEVICE specific tips, tricks, Caveats and nice to have changes here.

FEL mode

The something button triggers FEL mode.

Touchscreen

In most situations, you will need to disable multitouch on the FT5X touchscreen driver (for instance, by commenting out CONFIG_FT5X0X_MULTITOUCH in drivers/input/touchscreen/ft5x_ts.h).

The kernel for HWv2 has a working driver.

Device disassembly

Remove the 4 screws. Now gently push your Plastic tool between the plastic outer edge and the metal back cover. Try to go around the whole board until you hear some clips pop, and do this until all clips have released. Be careful when opening the device, as the Wifi antenna is taped to the back cover.

Locating the UART

Describe how to find the RX,TX,GND signals here, and mention the UART howto.
