Unable to display using framebuffer in i.mx8mqevk

[abhay]

Hi,

Am unable to display anything using frame buffer in i.mx8mqevk. I tried initially with ioctl system calls and later with some simple methods as , dd if=/dev/urandom of=/dev/fb0 and cat /dev/urandom > /dev/fb0.

Both methods didn't show any errors but display was not modified.

The display used is an HDMI monitor with resolution 1920x1080.

Was able to obtain the resolution from fb0.

Thanks in advance.
