Unable to program device using Diligent HS3 Programmer

Hi

 

I am trying program xilinx Artix 7 35T FPGA board using Digilent HS3 programmer. I connect 4 wires of JTAG correctly and also connect VCC and ground properly, whille programming FPGA error comes fpga is not detected.

JTAG HS3 is  detected in my PC properly .

one thing else i dont understand how to handle SRST pin in JTAG HS3.

 

Regards,

Mukesh Patel

Re: Unable to program device using Diligent HS3 Programmer

Hi @mukesh_patel,

I see that your JTAG clock frequency is pretty high (30MHz). The Artix-7 might not be able to communicate at that speed.

Could you please lower the JTAG frequency to 10MHz or less and see if the board gets recognized?

Thanks,

Re the specific reset pin on  the HS3,

  unless yo uhave a Zynq part,  it not part of JTAG , its an output fomr the HS3, ignore it , make it no connect.

HI All,

Thanks all for response Artix 7 communicate with 30 MHz JTAG clock.

Re: Unable to program device using Diligent HS3 Programmer

How do yo know your board , cable and laptop work at teh 30 MHz rate ?

 

unless you have good temrination on the JTAG , and a fast PC USB ( does not depend upon the CPU frequency , and good cables, you don't knwo unless you , meassure.
