Intel: When changing the FPGA design for Cyclone® V SoC/Arria® V SoC, a handoff file is generated. Is there a criterion for determining whether the preloader needs to be replaced?

Narrow down by specifying conditions

There are currently 4341 results.

Intel: In Cyclone® V SoC / Arria® V SoC, a handoff file is generated when the FPGA design is changed.

SoC FPGAs

Category: SoCs
Tools: Quartus® Prime
Device: Cyclone® V / Arria® V

This can be determined by the message during Quartus® Prime compilation.

When you need to replace preloader

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/soc_system_hps_0/, run the Preloadre Support Package Generator to update your Preloader software

When replacement of preloader is unnecessary

Hard Processor Subsystem configuration has not changed and a Preloader software update is not required.
