After looking for into Android source we detected that the propertie "rotate_screen" must be grater than 1 to rotate the screen.

Settings.System.PutInt(ContentResolver, "rotate_screen", 1);

Cubieboard v2 Hardware (A20 Based) / Pinout for LCD.
December 03, 2015, 02:50:00 am
Hi! I'm Marc!

We are working with a cubieboard2 (A20) and we want to burn an Android image into it. we have this LCD https://www.olimex.com/Products/OLinuXino/LCD/LCD-OLinuXino-10TS/open-source-hardware made for  A20-OLinuXino-MICRO device.

We created a board (this board is in production so we can't change it) which connect each pin from the cubie to the LCD connector. Cubie sends red color in lcdd0 (from lcdd0 to lcdd7) and blue in lcdd16 (form lcdd16 to lcdd23), but the problem appers because the LCD recieve blue through lcdd0-lcdd7 and red through lcdd16-lcdd23.

We try to swap red and blue changing the script.bin:

But it seems that has no effect. Anyone knows any solution that does not involve changing the board?

Thanks for all and sorry for my english.

Did you discover something? I need to read the voltages sended by a temperature sensor.

thanks.

Thanks for all @lex !  :) :)

Thanks for the info @lex. But for a bigger screen (15 or 18.4") I have to do the same work? Doesn't matter the size if both use gt811?Am I right?

Thanks for your reply @lex  :). I'll try it.

Hi!

I'm trying to do the same you do in https://drive.google.com/file/d/0B7A7OPBC-aN7bFFURkdLVkZGckk/view . Can you give me some instructions to achieve that. I'm working with a cubie2 (android, kernel 3.4).

Thanks in advance.
Marc.
