This section explains how to most easily identify your device. For a development board, explain the name(s) printed on the board. For an android device, find out the strings as reported under settings.
On the back of the device, the following is printed:
Manufacturer Marketing Name ModelNumber
The PCB has the following silkscreened on it:
In android, under Settings->About Tablet, you will find:
- Model Number: A70X
- Build Number: wing_k70-eng 4.2.2 JDQ39 20130906 test-keys
There is neither u-boot defconfig neither dts yet.
- 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.
If there is mainline U-Boot support, add this section.
For building mainline U-Boot, use the MANUFACTURER_DEVICE target.Don't forget to add
[[Category:Mainline_U-Boot]]at the bottom of the page.
If there is mainline kernel support, add this section.
Use the FAMILY-CHIP-DEVICE.dtb device-tree file for the mainline kernel.Don't forget to add
[[Category:Mainline_Kernel]]at the bottom of the page.
Tips, Tricks, Caveats
Add MANUFACTURER DEVICE specific tips, tricks, Caveats and nice to have changes here.
The something button triggers FEL mode.
Device specific topic
If there are no further device specific topics to add, remove these sections.
There is no upstream support for the GSL1680 touch-screen controller, interested people can connect some probe on the PCB to hack it.
Adding a serial port (voids warranty)
Insert your plastic tool between the front and back covers, and push the back cover outwards, you should soon hear the clips pop. Start at the corner nearest the loudspeaker.
Locating the UART
The UART pads are located next to the SOC, the TX and RX pin are marked on the PCB. Solder on some wires according to our UART howto.
