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 HMoha11,

May I know which configuration file you are using (eg. .pof, .sof, .pof)?

Can you change your JTAG frequency to the 6MHz (default value)?

Thanks

Hi MShafiq,

Thanks for your reply ,

I am using .pof configuration file. I think the board doesnt support other configuration like .sof

I will try reducing JTAG frequency.

May i ask you one question? Why do we need to reduce the clk freq.?

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.
