VC7222 - Power - No devices shown in VC7222 JTAG chain


When trying to program the VC7222 in Vivado Hardware manager, no devices are showing up in the JTAG chain.


This can be related to the GTH and GTZ power modules. If these modules are both unconnected, no devices will appear in the JTAG chain.

These modules are not soldered in, they are socketed, so they can easily be placed back in or removed.

Placing the power modules back onto the board will resolve the issue.
