Allwinner like all other Chinese manufacturers do not care to release complete documentation for their products. The reason is hidden in the Chinese model of manufacturing, the SoC company provides all — the ICs the reference design, the software support and then the factories manufacture products without any R&D, so releasing proper documentation is not top priority…
This results in situations like this when you have very simple problem… where you can't solve it for weeks and have to do reverse engineering and spend tons of time to fix something very simple which is not in their «support package».
A10-OLinuXino DDR for instance is wired a bit different than their official schematic and as there is no info for DDR controller at all we are now stuck several weeks and can't alive the A10 prototypes as we can't get any technical support nor specs from Allwinner.
