Hi all,

I've got a Ditter V21 HDMI Android TV stick, based upon Allwinner A31s SoC:

http://freaktab.com/forum/tv-player-support/allwinner-tv-players/10567-ditter-v21-a31s-1gb-ram

Mine gets with the two buttons on the main board (v1.3).

I'd like to get on FEL mode on this, and my first question to the group here is 
whether anyone can give more info about this board and where to find the serial 
pads on it (if any...).

I anyhow tried getting to FEL though button+power mode, just trying to push the 
right button while pluggin it the USB cable.

Seems like working (I think), as I can read basic FEL info, once plugged in:

$ sudo ./sunxi-fel ver
AWUSBFEX soc=00001633(A31) 00000001 ver=0001 44 08 scratchpad=00007e00 00000000 
00000000

but the 'fel read' command:

$ sudo ./sunxi-fel read 0x42400000 0x82d0 boot1.header 

just hangs... Later, also 'fel ver' fails (returns nothing). 
I also noticed chip getting very hot.

I managed to extract meminfo and script_extractor (from the Android stock 
firmmware), but I'm stuck.

I'd really like to contribute to the Wiki with my device, but apart from these 
info I can't provide much more...

Any suggestion?

thanks
Fabio
