This issue had been a pain ever since I started using the CMDO-A7 devices. In Windows 7, using Vivado 2016.2, if I open the hardware manager in Vivado to configure the device, after a few minutes Vivado decides that the target is no longer available and disconnects it. This is a particular problem when I am also using the USB UART... though the problem doesn't happen immediately. This issue makes using the ILA extremely difficult to impossible with this board.
When I use the Adept Utility for Windows to configure the board I can use the UART all day without a problem. I suspect a JTAG/UART driver related issue is to blame.
