ETMv3 target pinout
Blue colored signals are required for trace.
Note: Mictor 38-pin ARM ETM Cable Adapter features resettable fuses on pins 9, 11, 12, 15, 17, 19 and 21.
These protect debug signals against overcurrent and cycle back to a conductive state after the excessive current
fades away. Signals on pins 6, 16, 18, 20 and 22-38 are protected via 47 ohm serial resistors.
The adapter connects to the target via a 38-pin Mictor connector (Tyco Electronics 5767055-1). A target should
feature a matching part (for example Tyco Electronics 5767081-1 in SMT technology).
Texas Instruments TMS570 Microcontrollers
Targets based on Texas Instruments (TI) ARM microcontroller can feature MIPI 60-pin target debug connector
with Texas Instruments proprietary pinout instead of 38-pin Mictor. MIPI term stands for Mobile Industry
Processor Interface and is a standardized connector for debugging and tracing up to 40 data lines.
A dedicated adapter (converter) is available for Texas Instruments MIPI 60-pin pinout and can be ordered
separately under the IAMIC38MIPI60TMS570 ordering code.
Double check the pinout of the target debugs connector with the debug cable adapter pinout before connecting it
to the target for the first time.
