最近在配置qml运行环境时，遇到了一个OpenGL相关的报错：

EGL Error : Could not create the egl surface: error = 0x3003

解决办法参考下文：

I am currently using a 24bit parallel display, so in the .dtsi file inside fb@0, I set the default_bpp to 24. This needs to always be 16 regardless of the display. So I set default_bpp to 16 and I no longer get eglCreateWindowSurface() errors anymore!

    mxcfb1: fb@0 {
        compatible = "fsl,mxc_sdc_fb";
        disp_dev = "ldb";
        interface_pix_fmt = "RGB666";
        mode_str ="LDB-XGA";
        default_bpp = <16>;
        int_clk = <0>;
        late_init = <0>;
        status = "okay";
    }; 

 

可以在uboot里设置（写死的办法是可以在uboot源码或者设备树里改写）：

setenv video "video=mxcfb0:dev=ldb,LDB-XGA,if=RGB24,bpp=16 fbpix=RGB24 video=mxcfb1:off video=mxcfb2:off video=mxcfb3:off consoleblank=0 fbmem=28M ldb=dul0"
