JTAG signals are available at:
- gender-inverted standard 6-pin JTAG header connector J2;
- B2B connector J4.
JTAG Connector J2
JTAG signals are available on the dedicated header J2 through a JTAG programmer with flying leads as described in the table below.
TMS | | TDI | TDO | TCK | GND | Vref (3.3 V) |

To connect your computer to JTAG connector J2, you typically need
- a JTAG cable with standard 6-pin JTAG female header;
- a 2.54 mm pitch 1 × 6 pin gender changer header.
Some examples of JTAG cable set are listed in the table below.

Figure below shows a standard 6-pin JTAG female header, in this case flying leads, with a gender changer header.
The JTAG is ideal for quick configuration and effective debugging.
JTAG lines at B2B connector J4
JTAG signal lines are also available at B2B connector JM4 (pins 70, 72, 74, 76, 78 and 80). See the corresponding pin-out table for additional information on these signals.
