Inet k70hc

= Sunxi support =

Current status
U-Boot and boards patches are pending, but this hw is otherwise supported by our u-boot and our sunxi-3.4 kernel.

Wifi (8188eu) initialisation is sometimes flaky, association works ok, but dhcp fails to properly run... So one needs to manually start it on the ancient ubuntu version (precise) i (libv) am currently running.

The USB OTG port totally refuses to work. This needs to be properly debugged still.

Uart sometimes dies for no explicable reason. Characters get echoed back, but nothing further. This could be a bad connection with my handiwork.

Manual build specifics

 * For building u-boot, use the "INet_K70HC" target.
 * The .fex file can be found in sunxi-boards as inet_k70hc.fex

Everything else is the same as the mele example in the howto.

= Tips, Tricks, Caveats =

FEL mode
The back button triggers fel mode.

USB OTG port
This device comes with only a single USB port, and has no separate power connector. It therefor is only of limited use as a standalone desktop style device, as connecting a keyboard and/or mouse will only work as long as the battery lasts.

= Adding a serial port =

Opening the device
Remove the two screws on the side with the connectors.

Now gently insert your plastic tool (a cut off, sharpened toothbrush) in the space between the connector face and the back. You should soon hear the plastic clips popping. Be careful when removing the back, as the speaker is lightly glued to it.

Locating the UART
There are nice pads labelled "GND", "RX" and "TX" below the SD card. All you have to do is solder on some wires.
