SM750 graphics on a Custom QorIQ T4240 SBC

We have developed a custom SBC based on NXP Qoriq T4160 Processor and SM750 device connected on PCIe.

I have compiled the SM750 driver  through Yocto for Linux Kernel 4.1.35 and Linux booting was successful.

After that through insmod command installed the kernel module and i am able to see 2 framebuffers named /dev/fb0 and /dev/fb1 but when i try to display some random colors on vga/dvi nothing displayed at the output.

Is that anything i have to do in u-boot/dts for bringing up sm750?

Can anyone help in configuring SM750 and testing the interface.

I attached the log file which contains the commands executed at linux.

 

Thanks in advance,

Ranjith
