[Problem] help find R110~R113 resistors on board to LCD Rotation 180deg - msmmbl - 07-19-2017
I have an old MIPI LCD panel. It works fine with pine64 2GB version. I want to rotate the screen 180deg. I checked the board schematic and found the MIPI L/R Pin is 0, U/D is 1, which means LCD is mirrored and upside down.
So, I want to make L/D pin 1, U/D pin 0, which means LCD is in default direction according to the datasheet. Move the resistor R113 to R112, R111 to R110. I have two problems:
1. Where is the R110 to R113 on board?
2. The resistors are very tiny and it is difficult to move them. I am using Android 6. Is this have other way to rotate screen 180deg without rotate the touch panel?

Glad that you manage to interface up your old MiPi LCD panel. I will release the PINE A64 component location PDF on next week, so that you can locate the component location.
