I try to run example lcd16207 program from altera wiki and it doesnt work. Ive changed defined addresess to # define ADR_LCD_COMMAND na_lcd_16207_0 + 0x80000000 # define ADR_LCD_READY (na_lcd_16207_0 + 0x80000000 +4) # define ADR_LCD_DATA (na_lcd_16207_0 + 0x80000000 + 8) # define ADR_LCD_READ (na_lcd_16207_0 + 0x80000000 + 12) I have no idea what to do? Which drivers should I use? Ive tried to follow the steps from "Device drivers and Test application for a SOPC solution with Nios II softcore processor and μClinux" but I cannot find de2_drivers which were use there since the files are no longer available on the serwer. Please help me cause I am really confused now how it should work :)

Did you load the module before you want to use the application?
