Unsolved FB blanks screen and not display any thing

[rohitkhatri]

Hi,

We are using qt5.2 and development is in initial stage. OpenGL and EGL librariries are provided by silicon manufacturer. We have compiled QT5 successfully but when try to run examples, it blanks screen but not display anything.
Processor is HIsilicon's 3536 and we are using linux platform.
We tried to run given examples on system, but it didn't display anything.
Instead if we use fb-test utility, it displays picture. but application doesn't.
We passes parameters -platform linuxfb:fb /dev/fb0 -qws as well.
What mistake we have done? Is it compilation issue or any parameter is missing?

Regards
