Hi Folks,

I have a question.

Working on a “semi-custom” frame buffer for a Xilinx FPGA with the Microblaze.

The specific file we started with is already in the uclinux/drivers/video and is called xilinxfb.c

We can register the driver and a debug trace in the driver shows that it registers as FB0 29-0, so that should be right.

However, if I do a cat /dev/fb0 the linux responds by saying it can’t open the device. It appears that somehow the default file pointer in dev/fb0 cannot connect to the actual driver?

MKNODing the driver also fails.

I do have other drivers that we have made that do install, so this isn’t the first attempt at a driver.

Any thoughts on where I may look for some ideas on this?

Thanks!
