MIPI 34 connector
The MIPI 34 connector is a 34-way 1.27mm pitch box header which supports JTAG debug, Serial Wire Debug, SWO trace, and up to 4-bit wide continuous-mode TPIU trace.
The MIPI 34 connector supports separate voltage domains for the debug and trace signals. You must supply the appropriate voltages to both of the VTREF pins.
NoteThis connector is rarely used on target boards. The MIPI 34 adapter and debug cable is not supplied with the DSTREAM-ST unit, but are available on request.

|Pin||Signal name||Pin||Signal name|
|13||GND (1)||14||TRST_PD (2)|
- Although these pins are typically grounded on the target board, the MIPI specification also allows them to carry power. If they are connected to power rail (or rails) on the target board, these pins must also be AC coupled to GND using 100nF capacitors that are close to the connector.
- The TRST_PD signal allows the target board to have a second TAP reset signal which is normally pulled-down. For more information, see the MIPI debug connector specification.
- The TRACEEXT signal is not supported by DSTREAM-ST.
