Try un-plugging the compact flash card, if one is present. The CF socket and LCD share pins, so they cannot be used at the same time!

If you are new to Nios II then you should probably be using the IDE and the HAL software which comes with it rather than the legacy sdk (which is not recommended for new projects as its not being developed any more).
