EGL Error : Could not create the egl surface: error = 0x300b

Hi,

I have a Cubieboard embedded system:

http://cubieboard.org/

      1G ARM cortex-A8 processor, NEON, VFPv3, 256KB L2 cache  Mali400, OpenGL ES GPU  512M/1GB DDR3 @480MHz  HDMI 1080p Output  10/100M Ethernet  4Gb Nand Flash  2 USB Host, 1 micro SD slot, 1 SATA, 1 ir  96 extend pin including I2C, SPI, RGB/LVDS, CSI/TS, FM-IN, ADC, CVBS, VGA, SPDIF-OUT, R-TP..  Running Android, Ubuntu and other Linux distributions


The cubieboard is based on the AllWinner A10 SoC and this is what is available as documentation:

http://linux-sunxi.org/A10
http://linux-sunxi.org/Mali400

It uses Mali-400 MP for graphics - and I'm trying to use the Qt5 graphics framework with it.

Following the second link and installing the mali-libs from sunxi I'm able to display the coloured triangle and obtain the es_info2 output as stated.

When attempting to run a Qt5 App using the EGLFS platform, I'm getting:

EGL Error : Could not create the egl surface: error = 0x300b

So far I've managed to translate this error 0x300b to EGL_BAD_NATIVE_WINDOW but haven't got a clue about what it means and to solve it.


If anyone has any idea of why the error is showing, and how to fix it - please let me know.

Thanks in advance!

    I have exact same problem and it freaks me out.

    I'm trying to develop on Odroid-U2 with Mali-400 and even examples from Mali SDK fails on eglCreateWindowSurface() with EGL_BAD_NATIVE_WINDOW.

    I did a gdb and it looks like this:

    (gdb) s
    MaliSDK::EGLRuntime::initializeEGL (requestedAPIVersion=MaliSDK::EGLRuntime::OPENGLES2) at src/EGLRuntime.cpp:287
    287      surface = eglCreateWindowSurface(display, config, (EGLNativeWindowType)(platform->window), windowAttributes);
    (gdb) print platform->window
    $8 = (fbdev_window *) 0x1c0e8
    (gdb) n
    288      if(surface == EGL_NO_SURFACE)
    (gdb) print surface
    $9 = (EGLSurface) 0x0
    (gdb) s
    290          EGLint error = eglGetError();
    (gdb) n
    291          LOGE("eglGetError(): %i (0x%.4x)\n", (int)error, (int)error);
    (gdb) n
    Error: eglGetError(): 12299 (0x300b)

    So the platform->window handles correct fbdev_window structure, is accepted by eglCreateWindowSurface, but Surface is not created.
    I'm using X11 with Mali drivers tied to framebuffer, the only difference with other platforms is that Mali-fbdev on ODROID-U2 uses /dev/fb6 instead of /dev/fb0.

    Can anyone help me? What does this function expect as native window?
