Solution


ImpactThe TSU Counter will not increment properly if MIO26 is chosen as clock source
Work-aroundA different clock source must be chosen in the Processing System IP I/O Configuration tab.
If an external reference is needed, the PCB might need to be redesigned to use MIO50/51.
Configurations Affected MIO26 is configured to source GEM TSU_REF_CLK in the Processing System IP Wizard GUI.
ResolutionVivado 2018.3 and later versions display a Critical Warning when MIO26 is chosen in the Processing System IP GUI (PCW).
