ContributorAvalon-MM Cyclone V Hard IP for PCI Express Intel FPGA IP - Hard Reset to Soft Reset
Dear Intel, Really having a hard time on switch to soft reset. According to datasheet and forum discussion. Hard reset on the hard PCIe require a specified pin or pins to work. In order to fully ...
Ok the solution to resolve SRC under Hard PCIe RP:
The example from rocketchip and MitySOM gate the mgmt reset by nreset_status.
Due to pin_perst is not used -> 1'b1
The nreset_status will not release unless mgmt is reset with npor while gating mgmt reset bynreset_status will dead lock and never exit the reset.
