JTAG-ETM Splitter Probe

ADA-ETM-JTAG

A typical target board has both the JTAG signals and the ETM signals connected to the same standard 38-pin

ETM Mictor connector (see on p. 14). Some boards, however, separate the two types of signals, providing two

different connectors for them. These boards require a JTAG-ETM splitter probe, ADA-ETM-JTAG. This

probe is also useful when debugging an ARM or a DSP target board that does not have an ETM connector on

it.

25.4 mm (1 in), C = 33.9 mm (1.34 in).

FIGURE 38 The JTAG-ETM splitter board attached to the JTAGjet-Trace emulator. Connected to it are a 20-

pin ARM JTAG cable and an ETM Mictor cable (lower). A receptacle for an additional 14-pin TMS320 DSP

JTAG cable is located at the bottom of the board.
