JTAG[edit | edit source]

JTAG[edit | edit source]

JTAG port is available as two different mechanical connectors:

  • 2.00mm-pitch 7x2 header (Xilinx standard)
  • 2.54mm-pitch 10x2 header (ARM standard): http://www2.lauterbach.com/pdf/arm_app_jtag.pdf
  • This port is connected to Zynq's native JTAG signals. Please note that Zynq's internal JTAG chain supports differents configurations, depending on bootstrap signals. In case split mode is selected, CPU JTAG can be routed separately via PL. For more details please refer to Zynq Technical Reference Manual.
  • JTAG on BORA Xpress EVB is also connected to the FMC connector. For more details on how to connect JTAG on a custom FMC card please refer to ANSI/VITA FPGA Mezzanine Card (FMC) Standard.

JTAG XILINX - J13[edit | edit source]

J13 is a 14-pin 7x2x2 pitch vertical header. The following table reports the pinout of the connector:
