ti81xxfb: failed to start

Hello,

I have built kernel module ti81xxfb.ko. I insert this module with following command,

"insmod ./kermod/ti81xxfb.ko vram=0:8M,1:8M,2:8M". The module inserts successfully. But when I try to run my QT application, it fails to open /dev/fb0 node.

I have checked that /dev/fb0 node is available with right permission. Still it gives error,

QScreenLinuxFb::connect: Operation not permitted
Error opening framebuffer device /dev/fb0
LinuxFb: driver cannot connect

ti81xxfb: failed to start

Please note I am using IPNC_RDK_3.8.0 based kernel and file system.

What could be the issue ?. Please provide some suggestions.

Regards,

Krinali Shah
