Part Number:TDA2PXEVM

Tool/software: Linux

Hello:

    

  we can succeed to run the weston-simple-egl  on TDA2PxEVM board.

root@dra7xx-evm:~/build-avm_qt_app-TI_QT5_ARM-Debug# weston-simple-egl        
wlpvr: PVR Services Initialised
302 frames in 5 seconds: 60.400002 fps
^Csimple-egl exiting
wlpvr: PVR Services DeInitialised
root@dra7xx-evm:~/build-avm_qt_app-TI_QT5_ARM-Debug# 

and our Qt application run with "./avm_qt_app -platform eglfs

"

root@dra7xx-evm:~/build-avm_qt_app-TI_QT5_ARM-Debug# ./avm_qt_app -platform eglfs
[AVMS]log_init. server log_to_console=1, log_to_shm=1
EGLFS: Failed to open /dev/fb0
EGLFS: Can't continue without a display
Aborted (core dumped)

and seems it support eglfs, linuxfb, minimal, minimalegl, offscreen.

but why it failed to run with eglfs?
