17 years agoFPP Config of Arria II with Cyclone III
I'm trying to implement a system which consists of a Cyclone III, CFI flash, and an Arria II GX. I'd like to be able to use the parallel flash loader in the CIII to JTAG program the flash, as well as configure both the CIII and the Arria II GX.
Is this possible, or do I need to resort to using a MaxII to implement the PFL function? (I noticed that the PFL megafunction for CIII does not allow the operating mode to be set to "FPGA Configuration", as only "Flash Programming" is available as an option.)1 Reply

The FPGA configuration from connected parallel flash is performed by FPGA dedicated hardware rather than the PFL core. But you should be basically able to design a custom PFL version, that configures additional external FPGAs, by re-using the respective parts from the MAX II PFL design. The function could be completely separated from the PFL flash update operation, the latter even doesn't need to reside in your final design.
