Hi zare,

Probably you need to check the uboot parameters and resolution for RGB24, also you should try the unit test for the IPU, or the OBDS.

thanks for you reply,

I think my resolution settings is not wrong,  operating on mxcfb is ok,  just opengles has problem. below is the mxcfb testing result photo. and my display pinctrl settings follow it .

And where can i get ipu test units.

HI,

Please try the following :

      bootarg fbpix=BGR32

FYI:

Wrong Qt-Rendering with platform EGLFS

It's still not working, either I change ipu input pixel format in _setup_disp_channel1 to  IPU_PIX_FMT_BGR32.

I think there is problem when gpu translate data to ipu, but I can not find where it is .
