How do I change the display to use RGB24 instead of RGB666 in U-boot 2009.08?

Device info:

Processor: iMX6Q (Dual Core Version)

Uboot Version: 2009.08

BSP Version: Freescale Android BSP for KitKat 4.4.2_r1

I am working on a project that needs to use RGB24 for uboot, and this is mostly to correct the washed out image we are receiving for our splashscreen on an android device. Currently, the device is configured to use RGB666 in uboot, but it is connected to a 32 bit display.

Igor,

I went through that document, following the instructions carefully, but I am still not getting uboot to use RGB24. The main reason I know this is still the case is that the image is washed out. I had the very same issue with the Android home screen as well, and this was solved by altering the kernel to use RGB24. The attached image shows the issue with the splashscreen.

Thanks,

Michael
