Is the custom component connected to the NIOS CPU in your design? If so, check the base address for the custom component. In Eclipse, make sure to enable the small C libraries in the BSP editor when creating the project.

You can use the IOR/IOW commands to write to your custom component via the NIOS-2 CPU address space and offset.
