A.13.4. Trace Connectors

Trace connectors are provided on the PB-A8. Use the JTAG connector J10 to provide the JTAG signals that are required for controlling the ETM in the Cortex-A8.

The Mictor 19x2 way connector (part number AMP 2-767004-2) is shown in Figure A.18.

Note

Agilent (formerly HP) and Tektronix label these connectors differently, but the assignments of signals to physical pins is appropriate for both systems and pin 1 is always in the same place. The figure is labelled according to the Agilent pin assignment.
