display an image on my NEEK LCD

[Altera_Forum]

Hi all, 

I want to learn how to use my NEEK's LCD display from uclinux. For that reason, I want to use the lcd application that comes with the uclinux-dist (under user). In menu xconfig, I enabled the lcd example under Misc Applications. I download the image, start uclinux, and type lcd, I get the following output : opening lcddma...returned -1 lcd.c is trying to open /dev/lcddma. I checked uClinux-dist/linux-2.6.x/include/asm-nios2/nios2.h and I found lcd_sgdma I changed lcd.c to look for lcd_sgdma but kept having the same error. Any pointers ?  Thanks
