Hi there. Not quite sure where you are regarding the tags. The System ID Peripheral is in the Component Library in the SOPC builder.

Library > Peripherals > Debug and Performance > System ID Peripheral

What this does is create and store a couple of values that can be read from the data bus. These values are generated by the SOPC builder every time you generate your project.

You need to regenerate your BSP in Eclipse to update the expected values.

When you try and load your software Eclipse will attempt to read these values from the device and compare them with the expected values in the SOPC information file in your BSP.

The result is you can't try and load software onto a device that has been programmed with a different hardware design.

Remember that reset is active low so Pin 4 needs to be pulled high.

Also which version of the NIOS II are you using? All but the /e require a license and so are time limited, so make sure you are programming your Cyclone with the correct SOF before trying to load the software.
