= Tips, Tricks, Caveats =

FEL mode
The vol+ 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.



NAND chip
Informations read on mainboard : SAMSUNG 149

K9GB08V0M

SCBO

YDL750AZi

Currently (20140117) NAND access is not possible in our sunxi kernels. This is because the Samsung K9GBG08U0M is not known by libnand. A patch exist which adds support for this NAND chip. That patch should be integrated soon.

Installing to NAND
Awkwardly, the inet_86vz default image came with a 16MB boot partition, but the FAT filesystem on it thought it was 128MB large. You will have to create a fresh FAT filesystem when installing to NAND.

= Adding a serial port (voids warranty) =

This device exposes a nice set of pads on the mainboard, but there's a catch. These pads are wired to the SD controller, and you can choose, either have an SD card, or have serial. You cannot have both.

Here is a record of how i had to bend backwards to get this solved.

Device disassembly
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.
