Help for FPGA Flash Programming using HS2 for custom PCB design

Question

Hi,

We are designing our custom pcb and taking arty-7 35 for reference.

We have purchased JTAG HS2 cable and connected this to J8 connector of arty-7 35T FPGA. We have given power supply using adaptor. We are able to program arty7-35 in vivado hardware manager with both .bin and .bit file by changing jumpers for configuration type.

 

We are following arty-7 programming guide for flash memory configuration. Our doubt is will these steps works if we design our custom PCB with same sets of components?

Apart from that is there any dependacy of J8 connector with digilent proprietary USB JTAG circuit?

Hi @hello.parth,

The J8 connector is not connected with the USB JTAG circuitry as illustrated in section 4 of the Arty A7 reference manual here: https://reference.digilentinc.com/reference/programmable-logic/arty-a7/reference-manual#fpga_configuration. The JTAG HS2, as noted on the Digilent store page, includes the USB JTAG circuitry that is natively present on Digilent made boards.

Thanks,
JColvin
