Xilinx KC705 User Manual page 25

The JTAG connectivity on the KC705 board allows a host computer to download
bitstreams to the FPGA using the Xilinx software. In addition, the JTAG connector allows
debug tools or a software debugger to access the FPGA. The Xilinx software tool can also
indirectly program the Linear BPI or the Quad SPI flash memory. To accomplish this, the
software configures the FPGA with a temporary design to access and program the BPI or
Quad SPI flash memory device. The JTAG circuit is shown in
