I need the orange Pi lite registers mapping for a project but I can't find it anywhere. Does someone know the mapping of the registers?

  • \$\begingroup\$ @Andyaka no it does not have one \$\endgroup\$ – Ivano Donadi Aug 5 '16 at 13:13

  • \$\begingroup\$ agreed, in general anything Alwinner you are not supposed to have access to the chip docs, but unlike broadcom, the Allwinner docs are sometimes leaked or outright distributed despite the watermarks. \$\endgroup\$ – old_timer Aug 5 '16 at 20:04

I believe that one is based on the Allwinner H3 SoC. Presumably you have, or can find, a schematic for the PCB.

Here is a link to the 618-page datasheet for the SoC. For example, GPIO register locations are shown below:

  • \$\begingroup\$ thanks @Spehro Pefhany but I need some addictional registers apart from these. I have contacted the Orange Pi support and I will update this post as soon as I get an answer from them \$\endgroup\$ – Ivano Donadi Aug 6 '16 at 8:50
