opengles display incorrect on imx6q custom board

[zarelaky]

I’m porting 3.10.53 kernel to imx6qsabre based custom board, the board use rgb24 interface lcd panel,

pinctrl control config correct (u-boot logo display ok, kernel log display ok), rootfs build with yocto-layers,

but when i run a opengles 2.0 test program. it display as below,  someone can give me any ideas ?

regards.

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 .

my uboot pinctrl settings

#define DISPLAY_RGB_PAD_CTRL  MUX_PAD_CTRL(NO_PAD_CTRL)

    } },

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 .

No one can know what happened ?
