It looks like you are using a clean flash chip. The Allwinner drivers are not suitable for clean chips in general. Can you use the LiveSuit tool from the Allwinner SDK with an image to initialise the file system? I suggest you trying one from here: http://dl.linux-sunxi.org/SDK/A20/A20_SDK_20130319/lichee/tools/tools_win/USB_update_and_produce/
