Schematics for Tinker Board 2 / 2s

[Schematics for Tinker Board 2 / 2s]

Hi,

I'm sorry to ask but if anyone can offer the schematics of the tinker board 2 / 2s ?

And I mean the real complete document which should contains details around rk3399.

 

I know there is schematics document offered by official site, and it contains all kinds of blocks,

but except the core rk3399 part.

Instead, it gives a block diagram of rk3399.

 

I'm doing some porting work for tinker board 2s,

and desire a schematics like tinker board offered, but not the block diagram which I can't see the pin connection information to the rk3399 soc.

 

I will appreciate any help.
