Hi, I am using Cyclone iv ep4ce6e22c8n fpga development kit from dueprologic. When i try to flash the code it is taking more than 10 minutes to complete the flashing. Can you please answer to this question? Regards Hareesh

Hi Hareesh,

Sometime the signal integrity and timing prevents operating at 24 MHz. Thus, the optimum recommended value is 6 MHz (default value).

In addition, the TCK frequency cannot change using the USB-Blaster download cable.
