Chapter 5: Interconnect
5.6.2 AXI Clocks and Resets
Each interface has a single clock for all five channels that make up an interface. This clock is provided
by the PL.
All clocks must be active and all resets must be inactive on all PS-PL AXI interfaces for the GPV to
function properly. The entire PS might hang if this condition is not satisfied and a GPV access is
