In android, under Settings->About Tablet, you will find:
- Model Number: SoftwinerEVB
- Build Number: nuclear_evb-eng 4.0.4 IMM76D 20130418test-keys
- For building u-boot, use the "A13_MID" target.
- The .fex file can be found in sunxi-boards as hsg_h702.fex
Everything else is the same as the manual build howto.
Use the sun5i-a13-hsg-h702.dts device-tree file for the mainline kernel.
Tips, Tricks, Caveats
The Volume+ button triggers FEL mode.
Adding a serial port (voids warranty)
Locating the UART
On the front of the mainboard, there are two test pads next to the SoC. Solder on some wires according to our UART howto. These pads are connected to UART1, and are not multiplexed with the SD card.
