Hi.
On our am335x based board, we're using u-boot (2013.10-ti2013.12.01), kernel (3.12.10-ti2013.12.01), and graphics SDK (5.01.01.01) from am335x starter kit SDK 07.00.00.00.
The graphics modules are re-built with: BUILD=release OMAPES=8.x FBDEV=yes SUPPORT_XORG=0 EGLIMAGE=0 PM_RUNTIME=yes
Qt 4.8.6 is re-built with configuration:
-prefix /usr/local/qt4
-release -opensource -confirm-license
-shared -fast -no-largefile -no-accessibility
-no-xmlpatterns -no-multimedia -no-audio-backend -no-phonon -no-phonon-backend

-D QT_NO_QWS_CURSOR -D QT_QWS_CLIENTBLIT
The graphics SDK OpenGL ES 1/2 demos run properly on the device. However, the qt hello_gles2 application creates a window with an empty green background. (textures example does the same) It also prints this error:
QEglContext::createSurface(): Unable to create EGL surface, error = 0x300b*** glibc detected *** ./hellogl_es2: double free or corruption (!prev) 0x0002a570 ***
Also, on serial console, there is a backtrace of error: (Please visit the site to view this file)
I followed the instructions on http://processors.wiki.ti.com/index.php/SGXDbg to no avail. As suggested by https://gforge.ti.com/gf/download/docmanfileversion/265/4572/qt_powervr_dbg.txt, I applied the patch from https://gforge.ti.com/gf/download/docmanfileversion/264/4456/qt_wsegl_1.6.tar.gz
The output of gfx_check.sh: (Please visit the site to view this file)
Am I missing something? Any suggestions about this issue?
Thanks,
