A.1
Debug connectors
The MPS3 board provides connectors that support P-JTAG processor debug, F-JTAG FPGA debug,
16
‑
bit and 4
‑
bit trace, and SWD.
This section contains the following subsections:
•
•
•
A.1.3 20-pin Cortex debug and ETM connector
•
•
A.1.5 14-pin F-JTAG ILA connector
•
A.1.1
20-pin IDC connector
The MPS3 board provides one 1V8 20
‑
pin IDC connector that supports P
‑
JTAG processor debug to
enable connection of DSTREAM, or a compatible third
‑
party debugger. The connector also supports
Serial Wire Debug
(SWD).
The 20
‑
pin IDC connector connects to general
‑
purpose pins on the FPGA. The availability of P
‑
JTAG or
SWD depends on the design that you implement in the FPGA.
The following figure shows the 20
‑
pin IDC connector, J14.

The following table shows the pin mapping for each P
‑
JTAG and SWD signal on the 20
‑
pin IDC
connector.

Note
• Pins 1, 3, 5, 7, 13, 15, and 19 have pullup resistors to
1V8
.
• Pins 9, 11, and 17 have pulldown resistors to
GND
.
