The image for Allwinner A10 currently supports the Mele family of arm computers using HDMI at 720p.
However, as Marco pointed out it works equally well on his Allwinner tablet with, for now, a connected usb keyboard.
To help the effort and try your Allwinner device you will need to copy the file named script.bin from your device. This file resides on nanda a vfat filesystem not easily accessible. I am sure you could use ADB to fetch it, but I prefer the standard Unix approach. Most Allwinner devices come already rooted.
How to get script.bin from your Allwinner device via ssh:
1. Install dropbear for Android, free in the Play Store and configure it.
2. Start dropbear SSH server on your Android Allwinner device.
3. From your x86 Core ssh root@ip number as displayed from dropbear Android server
4. mkdir /mnt/test
5. mount -t vfat /dev/block/nanda /mnt/test
6. ls -l /mnt/test (look for script.bin)
7. Open another xterm on Core.
8. scp root@ip as displayed from dropbear Android server:/mnt/test/script.bin .
9. exit your ssh session.
10. Stop dropbear ssh server app on Android.
Now copy your script.bin to the sdcard containing the a10Core image that you downloaded.
Try booting your Allwinner device from your updated sdcard.
If it works please post here and state your device specific.
I would be interested to know if it works on A13 devices.
Perhaps I will host many script.bin file listed by specifc target name,
Or if you already have a script.bin working with a10Core please post.
