This Debian image for A13-OLinuXino with Hynix DDR3 RAM boots and works well except for the touchscreen.
Manual build
Mainline U-Boot can be compiled for this tablet using the A13-OLinuXino_defconfig. For the LCD to work, edit the .config file to add the LCD config for Inet 86vs from this page: LCD.
Otherwise, follow the Manual build howto.
UART
As in all other A13 boards, you cannot use microSD and UART at the same time. You have to boot from USB instead.
Consider using a MicroSD Breakout to avoid soldering. Alternatively, the Rx/Tx pads are right next to the SD card socket on the top, or in the same place on the bottom (in the same layout as in the Inet 86vs but unlabeled).
UART is disabled and configured completely wrong in the default script.bin file, so instead of the testing method suggested in the UART guide, you'll need to boot uart0-helloworld-sdboot.sunxi from USB:
sudo sunxi-fel -v uboot uart0-helloworld-sdboot.sunxi
