Red / Blue Swap when SGX Is Enabled on OMAP3530

Hello Chris,

           SGX writes the data only in ARGB format to the FB. So I don't think it would be possible to address the

issue with your current setup unless 'B' and 'R' lines are swapped on your display.

My system was working with correct colors, but without SGX before.  I added SGX to the ICS build, and the red and blue swapped.  For this reason I'm thinking there is something going on inside SGX to swap them.

Chris,

      It happened because you might be having a software work around in Android which handles above case. But with SGX such a workaround is not possible as it always outputs in ARGB format to the FB.

Hi ,

I too have the similar problem, the processor used is DM3730 and the LCD  is configured for ARGB_8888.

When booting the board using the Linux the image colour is fine but when starting the android booting  the blue and red image are inter-changed.

Can you please guide me on this issue.

Thanks and Regards,

In my case I was fortunate because the LCD panel I used had a bit in the settings options to swap red and blue.

Thanks for the information. 

we have configured the Display

DISPC_CPR_COEF_R
DISPC_CPR_COEF_G
DISPC_CPR_COEF_B

in-order to correct the color swapping.
