Re: [microblaze-uclinux] Frame buffer driver

Hi,

I think I finally figured out how to instantiate the platfrom_device structure from autoconfig.h to include the TFT controller. So the last step is to make use of the new hardware. I don't think there is a Xilinx frame buffer console, should I enable virtual terminal and console on VT support? I tried compiling with the two options on but failed since there are some VGA definitions (asm/vga.h) missing. Is there any suggestion before I dig deeper in the mud?

Thanks,

Simon

Hi John,

I have the TFT controller updated to PLBv46. I also got an updated driver from the Xilinx source tree (git.xilinx.com). I even managed to modify menuconfig to include the driver and got it compiled. However I am not sure all the video controller parameters in Kconfig.auto are passed correctly or at all since the video controller and xilinxfb are not officially supported in version 2.6-0.3, correct? The other thing is I don't know how to enable the frame buffer console. So even the driver and device work correctly, I will not be able to see anything anyway. So my immediate question is how to turn on FB console.

Thanks,

Simon

There is one in the 2.4 source tree - drivers/video/xilinxfb.c

however, it has not been ported to 2.6. It would not be difficult I
don't think.

I'm also not sure if you can connect the plb_framebuffer to the new
version of PLB bus in EDK9.2? It might be necessary to modify the PLB
interface component of the framebuffer device.

John
