Qsys reset bus and its warnings

Hello guys,

I am experiencing an interesting problem, where the Nios CPU, that has been working on Quartus 12.1 now resynthesized on Quartus 13.0sp1 doesn't work. I've also made a QSYS system regeneration using new components, that came with the new Quartus version.

I am starting Nios from on-chip memory, which has initialization hex already assigned. The vectors are set up correctly, everything shows into on-chip memory as it was before in Q12.1. I don't have any ideas what could be wrong, but now, when generating QSYS system, I get hundreds of these warnings:

Warning (12251): Qsys_system: "No matching role found for rst_controller:reset_out:reset_req (reset_req)"

nios2-download says, that the system is not running, so probably Nios stays in reset.

I've double checked the reset signal also tried manually set the reset_n to '1', but the situation is the same.

There are no timing problems shown in TimeQuest analyzer, so I am pretty sure, that I am not experiencing system bus stalls.

Maybe someone could point me out what I am missing?

Thanks.
