Hi,

And according to the Orange Pi PC2 and Prime schematics, they both start at 1.1V. (The Prime schematics even says "For H5 adjust VDD-CPUX to 1.1V).
Orange Pi PC2 starts at the same voltage as Orange Pi PC. That is at 1.308V.
It can be calculated from 0.6×(1+11.8÷10) as per the values of Ru1/Ru2 resistors in the schema. It is also my experience of working with these boards and writing the sy8106a driver.
Anyway, I may be mis-remembering in the case of PC2. So please ignore me. :) I'm only sure in the case of Orange Pi PC, which is not relevant here. Sorry.
regards, Ondrej
There's no need to enforce a SoC-wide change.
