Although this thread is very old. But I am just posting one of my experiences here, so that people may be befitted with it. Here are some possible fixes for this situation.

When system ID is not detected or timestamp, it is possible that some of irq signal from any peripheral is not connected in qsys, If so, connect all required irq signals and then regenerate the system. Update new .qip file in the project. And then use the generated schematic or hdl files.

Second problem may be connections in Schematic. Make sure that all the ports are connected to module. Look for any X(cross) symbol at the end of the connecting lines.

Thirdly, about elf downloading fail: When ever a new Qsys system is generated, regenerate bsp. Then in application project Index -> regenerate. Then Build project, and then run.
