eglCreateWindowSurface return error 0x300B

We are trying to use EmbeddedWizard GUI platform with the iMX6DL. We have a problem while creating windows surface.
eglCreateWindowSurface function returns with error code 0x300B (BAD NATIVE WINDOWS).

I think, it is about the version of libEGL. I tried it with following images of toradex

Colibri-iMX6_Console-Image-Tezi_3.0b4.25

Colibri-iMX6_LXDE-Image-Tezi_2.8b6.184

Then I use Yocto to create two different images from the Index of /toradex-bsp-platform.git -b LinuxImage3.0 with the below changes in the local.conf file

First one:

DISTRO_FEATURES_remove = "x11 directfb wayland"
ACCEPT_FSL_EULA = "1"
IMAGE_INSTALL_append_mx6 = "eglinfo-fb"
IMAGE_FEATURES += "tools-debug tools-sdk"
CORE_IMAGE_EXTRA_INSTALL += "openssh openssh-sftp-server"
CORE_IMAGE_EXTRA_INSTALL += "dhcp-server dhcp-client "

Second one:

DISTRO_FEATURES_remove = "x11 wayland"
ACCEPT_FSL_EULA = "1"
IMAGE_INSTALL_append_mx6 = "eglinfo-fb"
IMAGE_FEATURES += "tools-debug tools-sdk"
CORE_IMAGE_EXTRA_INSTALL += "openssh openssh-sftp-server"
CORE_IMAGE_EXTRA_INSTALL += "dhcp-server dhcp-client "

As I understood, the problem occurs from EGL library. It has different modes, like framebuffer, directfb and X11. Is configuration correct for the framebuffer mode? Or do we need to make any changes?

This is the method of creating window surface.

eglDisplay = eglGetDisplay( EGL_DEFAULT_DISPLAY );  // no error occured after this
eglInitialize( eglDisplay,&EglVer0, &EglVer1 ); // no error occured after this
eglBindAPI( EGL_OPENGL_ES_API ); // no error occured after this
eglChooseConfig( eglDisplay, configAttribs, &eglConfig, 1, &num_configs ); // no error occured after this
eglSurface = eglCreateWindowSurface( eglDisplay, eglConfig, 0, 0 ); // BAD_NATIVE_WINDOWS error occures after this.

Hi @gnz and welcome to the Toradex Community!

Did you check this community thread about a similar topic? You basically have to make sure that you don’t have x11 or wayland in your DISTRO_FEATURES and that you add eglinfo-fb to the configuration. For this adding DISTRO_FEATURES_remove = "x11 " to your conf/local.conf is enough, since the Colibri iMX6 uses the tdx-x11 distro configuration which is on x11 and removes wayland by default. Also add eglinfo-fb with IMAGE_INSTALL_append_mx6 = " eglinfo-fb". In total:

 DISTRO_FEATURES_remove = "x11"
 ACCEPT_FSL_EULA = "1"
 IMAGE_INSTALL_append_mx6 = " eglinfo-fb"
 IMAGE_FEATURES += "tools-debug tools-sdk"
 CORE_IMAGE_EXTRA_INSTALL += "openssh openssh-sftp-server"
 CORE_IMAGE_EXTRA_INSTALL += "dhcp-server dhcp-client "

Additionally, you have to make sure to remove all buildoutput when you change the DISTRO_FEATURES variable.

rm -rf build/tmp-glibc/* sstate-cache/*

With that, I had the eglinfo-fb on my target. Did you check if your build was successful and if you can run eglinfo-fb on the target?

If it is still not working, would you have the full sample code with a proper Makefile to be able to reproduce the issue?

Best regards
Diego

Yes I have the eglinfo-fb on the target

No valid context: EGL failed to allocate resources for the requested operation.
eglMakeCurrent() failed: Arguments are inconsistent (for example, a valid context requires buffers not supplied by a valid surface).

I’ve attached the source codes and the makefile for my project. I am new to Linux and OpenGL. Do we need vivante-fb.so for using OpenGL or not?

The problem was solved. Problem was my code. To use EGL with iMx6 frame buffer, NativeDisplayWindows needs to be changed like this.

GnzNativeDisplay = fbGetDisplayByIndex(0);
GnzNativeWindow = fbCreateWindow(GnzNativeDisplay,0,0,0,0);
eglDisplay = eglGetDisplay(GnzNativeDisplay);
eglInitialize( eglDisplay, 0, 0 );
eglBindAPI( EGL_OPENGL_ES_API );
eglChooseConfig( eglDisplay, configAttribs, &eglConfig, 1, &num_configs );
eglSurface = eglCreateWindowSurface( eglDisplay, eglConfig, GnzNativeWindow, 0 );

Hi @gnz

I am happy to hear that! Thank you for the notification.
