Part17: JTAG Debug Port
The AX7350B FPGA development board integrates the JTAG download
debug circuitry so users do not need to purchase additional Xilinx downloader.
With a USB cable, you can develop and debug ZYNQ. On the AX7350B FPGA
development board, a FTDI USB bridge chip FT232HL is used to realize USB
of PC and JTAG debug signals TCK, TDO, TMS, TDI of ZYNQ for data
communication.
Figure 17-1: JTAG Interface Schematic
On the AX7350B FPGA development board, the JTAG interface is in the
form of USB interface. Users can connect the PC and JTAG interface to the
