5.1 Debug connectors
This section describes the MPS2 and MPS2+ board connectors that support P-JTAG processor debug, F-
JTAG FPGA debug, 16-bit Trace, 4-bit Trace, and SWD. This section describes the connectors and lists
their signals.
This section contains the following subsections:
• 5.1.1 JTAG 14 connector on page 5-75.
• 5.1.2 JTAG 20 connector on page 5-76.
• 5.1.3 CoreSight 10 connector on page 5-76.
• 5.1.4 CoreSight 20 connector on page 5-77.
• 5.1.5 MICTOR 38 connector on page 5-78.
5.1.1 JTAG 14 connector
The MPS2 and MPS2+ FPGA Prototyping Boards provide one F-JTAG, ILA, connector that supports
FPGA debug. It enables you to connect an ILA device, such as SignalTap II, to a hard FPGA JTAG chain
in the FPGA and debug your design.
The JTAG 14 connector connects to general‑purpose pins on the FPGA. The availability of F-JTAG
depends on the design which you implement in the FPGA. The MPS2 and MPS2+ FPGA Prototyping
Boards label this connector as FJTAG.
The following figure shows the JTAG 14 connector.

The following table shows the F-JTAG connector pin mapping for each ILA signal on the JTAG 14
connector J24.

Pin Signal Pin Signal
1 GND 2 +3V_EXT
3 GND 4 FPGA_TMS
5 GND 6 FPGA_TCK
7 GND 8 FPGA_TDO
9 GND 10 FPGA_TDI
Note
• Pins 4, 8 and 10 have pullup resistors to 3V.
• Pin 6 has a pulldown resistor to GND.
