Hi @fllf2005,

You should attempt to open with a default JTAG clock frequency that is 15 MHz for the
Digilent cable connection and 6 MHz for the USB cable connection. If it is not possible to
connect at these speeds, Xilinx recommends that you lower the default JTAG clock
frequency.

Hope this helps.
