How to use fbdev_pixmap structure passed to eglCreatePixmapSurface create Surface

Hi,
I now use the fbdev window system, I assign a fbdev_pixmap structure configured corresponding content, pass it to eglCreatePixmapSurface function, but get to the error information 0x0000300A
Such as:
Error: eglCreatePixmapSurface failed Error: 0x0000300A
I will be how to configure fbdev_pixmap structure content, there is no successful example sent to me ah?

Thank you

I am now using mali 400mp2 platform, the repository is framebuffer-r3p0;

examples are as follows:

static EGLint const config_attribute_list[] = {
    EGL_SURFACE_TYPE, EGL_PIXMAP_BIT,// EGL_PBUFFER_BIT EGL_WINDOW_BIT
    EGL_RENDERABLE_TYPE, EGL_OPENGL_ES2_BIT,
    EGL_NONE
};


  setenv("EGL_PLATFORM", "fbdev", 0);
  setenv("FRAMEBUFFER", argv[1], 0);

  struct fbdev_pixmap surface = {
         .width = 1920,
         .height = 1080,
         .bytes_per_pixel = 32,
         .red_size = 8,
         .green_size = 8,
         .blue_size = 8,
         .alpha_size = 8,
         .flags = FBDEV_PIXMAP_DEFAULT,
         .format = 1,
  };

  egl_dpy = eglGetDisplay(EGL_DEFAULT_DISPLAY);

   if (!eglInitialize(egl_dpy, &egl_major, &egl_minor)) {
      printf("Error: eglInitialize() failed\n");
      return -1;
   }

   if (!eglChooseConfig(egl_dpy, config_attribute_list, &config, 1, &num_configs)) {
      printf("Error: couldn't get an EGL visual config\n");
      exit(1);
   }

   assert(config);
   assert(num_configs > 0);


    EGLint ai32ContextAttribs[4];
    i=0;
    ai32ContextAttribs[i] = EGL_NONE;
    ai32ContextAttribs[i++] = EGL_CONTEXT_CLIENT_VERSION;
    ai32ContextAttribs[i++] = 2;
    ai32ContextAttribs[i] = EGL_NONE;


       eglBindAPI(EGL_OPENGL_ES_API);


   ctx = eglCreateContext(egl_dpy, config, EGL_NO_CONTEXT, ai32ContextAttribs );
   if (!ctx) {
      printf("Error: eglCreateContext failed\n");
      exit(1);
   }

    EGLint        attrib_list[16];
    attrib_list[0] = EGL_NONE;

   *surfRet = eglCreatePixmapSurface(egl_dpy, config, winRet, attrib_list);

   if (!*surfRet) {
          printf("Error: eglCreatePixmapSurface failed Error:0x%08X\n", eglGetError());
          exit(1);
   }

The program prints the error：

Error: eglCreatePixmapSurface failed Error: 0x0000300A

May I ask how to configure struct fbdev_pixmap, do not know if there are no relevant success stories?
