I think I may have a bad SmartLynq cable. When I plug it into an official Xilinx board (I've tried zcu102 and zcu216), I can connect to the cable from Vivado, although the cable does not detect any hardware targets. I have updated the cable firmware and I am using Vivado version 2020.1
In the exact same configuration, a different SmartLynq cable *does* work and detect hardware targets.
Are there additional debugging steps that I can try, or should I start an RMA for the cable?
