Linux 2.6 frame buffer for XUPV2P

Reply to Author | View Threaded | Show Only this Message

Hi all, I have run Linux 2.6 from git.xilinx.com on my XUPV2P board. This vendor kernel version is 2.6.28-rc6. Currently, the uartlite and ethernet mac work ok, but xilinx frame buffer driver seems not working, as nothing is shown on the VGA monitor, and nothing related to framebuffer is shown in the serial output. I run fbset,  but it says fb0 not found.
The hardware framebuffer IP core I use is the plb_tft_cntlr_ref 1.00.d, which is a PLB master and DCR slave, and the  opb2dcr_bridge acts as the DCR master.
Can someone suggest where the problem might be?

Please post your kernel .config and your dmesg output.

Try the following things:

1) Change the following line in the dts:
> compatible = "xlnx,plb-tft-cntlr-ref-1.00.d";

to 'compatible = "xlnx,plb-tft-cntlr-ref-1.00.a";'

2) add '#define DEBUG' to the top of drivers/video/xilinxfb.c before
the first #include statement and post the dmesg output.

3) look in /sys/bus/of_platform/devices to see if there is a directory
for the xilinx framebuffer device.

Thanks Grant!
    It works after I follow your advice 1) & 2). The small Linux logo is shown on the screen,

And I got the following from dmesg:
xilinxfb: calling of_register_platform_driver()
xilinxfb a08f8b00.tft: xilinxfb_of_probe(dfaaee00, c02bfde0)
Console: switching to colour frame buffer device 80x30
xilinxfb a08f8b00.tft: fb: phys=1f000000, virt=ff100000, size=1e0000


Best Regards & Merry Christmas!

Okay, good.  It's not the final solution, but I know what I need to
fix now and it gets you working.

Cheers,
