New ContributorHow to inject a crc_error into CycloneIV device
In AN539, a crc_error can be inject into a CycloneV device, when I do the same thing on a CycloneIV device, the crc_error pin pullup, but, when I pulldown nconfig(100us) , the crc_error pin pulldown ...
Hello,
Unlike Cyclone V, Cyclone IV does not support in-system CRC error injection and recovery via nCONFIG pin alone. When CRC error occurs-Cyclone IV will enter configuration failure state.
Recovery from this state will require full reconfiguration cycle.
If CRC error remains high- consider to power cycle your board.
