HPS change from Quartus II 19.1 to 21.1 - HPS change from Quartus II 19.1 to 21.1 Hello, we upgraded our Quartus II Software from V19.1 to Version 21.1. We ran a full compilation without any changes of our design files. Everything works fine, except this warning: Warning (11713): The configuration of the Hard Processor Subsystem (HPS) within this design has changed. The Preloader software that initializes the HPS requires an update. Using hps_isw_handoff/system_hps_0/, run the Preloader Support Package Generator to update your Preloader software Do we really have to update the preloader? If yes, why? What is the change in the configuration of the HPS? Thanks in advance, Patrick Replies: Re: HPS change from Quartus II 19.1 to 21.1 Hi PWeis4 , I will close this thread for now.

Since it's just a warning, you don't have to regenerate the preloader.
