Where you guys getting this error:

I tried following the instructions from the wiki http://nioswiki.jot.com/wikihome/operating...ems/framebuffer (http://nioswiki.jot.com/wikihome/operating...ems/framebuffer)

but I ran into this error when trying to run make in the uClinux-dist/

arch/nios2nommu/drivers/altfb.c: In function `altfb_probe&#39;:

arch/nios2nommu/drivers/altfb.c:161: error: `na_vga_controller_0&#39;

Do you have the vga_controller_0 hardware in your SoPC Builder system? The software# def&#39;s are telling you that you need it. The Wiki should tell you where you can find it. If not, a quick search through the forum should yield results.

Cheers, and Good luck!

You must disable these two console,

Device Drivers --> Graphics support --->

Console display driver support --->

[ ] VGA text console
