I'm using Vivado v2020.2 (64-bit) with a newly purchased Arty S7. The Arty manual shows a schematic with USB (J10) connected to the JTAG interface of the FPGA and says "A PC can use the Digilent USB-JTAG circuitry (port J10) to program the FPGA any time the power is on" then goes on to say "The Xilinx tools typically communicate with FPGAs using the Test Access Port and Boundary-Scan Architecture, commonly referred to as JTAG. During JTAG programming, a .bit file is transferred from the PC to the FPGA using the onboard Digilent USB-JTAG circuitry (port J10) or an external JTAG programmer, such as the Digilent JTAG-HS2, attached to port J9." It sounds to me like only a USB cable is required and, if that's the case, I'm confused as to why the JTAG-HS2 cable would be needed. Con someone confirm I need only a USB cable and clarify what all the JTAG devices listed for sale in the Digilent store are used for?
