JTAG Connectors and Pinout

# Introduction Texas Instruments supports a variety of JTAG connection methods to both its development kits and custom boards. This page covers in detail several aspects to properly identify, specify and use these different standards. # References * [XDS Target Connection Guide](emu_xds_target_connection_guide.html) * [Emulation and Trace Headers Technical Referece Manual](https://www.ti.com/lit/ug/spru655i/spru655i.pdf) * [JTAG Adapters](emu_jtag_adapters.html) * The document [Designing for JTAG Emulation Reference Guide](https://www.ti.com/lit/ug/spru641/spru641.pdf) describes the 14-pin JTAG connector and target board electrical requirements for XDS510 JTAG support (despite it's title it is not specific to the TMS320C6000 DSP). * The [XDS560 Emulator Technical Reference](https://www.ti.com/lit/ug/spru589a/spru589a.pdf) * For Trace, you may also want to consider reading [Common Trace Transmission Problems and Solutions](https://www.ti.com/lit/an/spraak6/spraak6.pdf) * [Emulation Fundamentals for TI's DSP Solutions](https://www.ti.com/lit/an/spra439e/spra439e.pdf) # Pinout * Part numbers for connectors and headers are at the bottom of the table and at section [Connector Information](#connector-information). * For the TI 60 pin connector and the MIPI 60 pin connector, please check the [Emulation and Trace Headers TRM](https://www.ti.com/lit/ug/spru655i/spru655i.pdf). * For MSP430 see [JTAG for MSP430](https://processors.wiki.ti.com/index.php/JTAG_%28MSP430%29) for details. * For ARM connectors, see [Cortex debug connectors](http://infocenter.arm.com/help/topic/com.arm.doc.faqs/attached/13634/cortex_debug_connectors.pdf) <table id="stl01"> <tr> <th> JTAG connector </th> <th rowspan="2"> TI 14-Pin1 </th> <th rowspan="2"> Compact TI 20-Pin (cTI)2 </th> <th rowspan="2"> ARM 20-Pin Cortex Debug + ETM3 </th> <th rowspan="2"> ARM 10-Pin3 </th> <th rowspan="2"> ARM 20-Pin1 </th> <th rowspan="2"> ARM 14-Pin1 (OBSOLETE) </th> <th rowspan="2"> TI 20-Pin1 (OBSOLETE) </th> </tr> <tr> <th> Pin number </th> </tr> <tr> <th> 1 </th> <td> TMS </td> <td> SWDIO / TMS </td> <td> VTRef </td> <td> VTRef </td> <td> VTRef </td> <td> VTRef </td> <td> VTRef </td> <tr> <tr> <th> 2 </th> <td> nTRST </td> <td> nTRST </td> <td> SWDIO / TMS </td> <td> SWDIO / TMS </td> <td> VSupply </td> <td> GND </td> <td> VSupply </td> </tr> <tr> <th> 3 </th> <td> TDI </td> <td> TDI </td> <td> GND </td> <td> GND </td> <td> nTRST </td> <td> nTRST </td> <td> nTRST </td> </tr> <tr> <th> 4 </th> <td> TDIS </td> <td> TDIS </td> <td> SWDCLK / TCK </td> <td> SWDCLK / TCK </td> <td> GND </td> <td> GND </td> <td> TDIS </td> </tr> <tr> <th> 5 </th> <td> VTRef </td> <td> VTRef </td> <td> GND </td> <td> GND </td> <td> TDI </td> <td> TDI </td> <td> TDI </td> </tr> <tr> <th> 6 </th> <td> KEY </td> <td> KEY </td> <td> SWO / TDO / EXTa / TRACECTL </td> <td> SWO / TDO </td> <td> GND </td> <td> GND </td> <td> KEY </td> </tr> <tr> <th> 7 </th> <td> TDO </td> <td> SWO / TDO </td> <td> KEY </td> <td> KEY </td> <td> SWDIO / TMS </td> <td> TMS </td> <td> TMS </td> </tr> <tr> <th> 8 </th> <td> GND </td> <td> GND </td> <td> NC / EXTb / TDI </td> <td> NC / TDI </td> <td> GND </td> <td> GND </td> <td> GND </td> </tr> <tr> <th> 9 </th> <td> RTCK </td> <td> SWDCLK / RTCK </td> <td> GNDDetect </td> <td> GNDDetect </td> <td> SWDCLK / TCK </td> <td> TCK </td> <td> TCK </td> </tr> <tr> <th> 10 </th> <td> GND </td> <td> GND </td> <td> nRESET </td> <td> nRESET </td> <td> GND </td> <td> GND </td> <td> GND </td> </tr> <tr> <th> 11 </th> <td> TCK </td> <td> TCK </td> <td> GND / TgtPwr+Cap </td> <td> </td> <td> RTCK </td> <td> TDO </td> <td> RTCK </td> </tr> <tr> <th> 12 </th> <td> GND </td> <td> GND </td> <td> TRACECLK </td> <td> </td> <td> GND </td> <td> SRST </td> <td> GND </td> </tr> <tr> <th> 13 </th> <td> EMU0 </td> <td> EMU0 </td> <td> GND / TgtPwr+Cap </td> <td> </td> <td> SWO / TDO </td> <td> VTRef </td> <td> TDO </td> </tr> <tr> <th> 14 </th> <td> EMU1 </td> <td> EMU1 </td> <td> TRACEDATA[0] </td> <td> </td> <td> GND </td> <td> GND </td> <td> GND </td> </tr> <tr> <th> 15 </th> <td> </td> <td> nRESET </td> <td> GND </td> <td> </td> <td> nRESET </td> <td> </td> <td> nRESET </td> </tr> <tr> <th> 16 </th> <td> </td> <td> GND </td> <td> TRACEDATA[1] </td> <td> </td> <td> GND </td> <td> </td> <td> GND </td> </tr> <tr> <th> 17 </th> <td> </td> <td> EMU2 </td> <td> GND </td> <td> </td> <td> NC / DBGRQ </td> <td> </td> <td> NC </td> </tr> <tr> <th> 18 </th> <td> </td> <td> EMU3 </td> <td> TRACEDATA[2] </td> <td> </td> <td> GND </td> <td> </td> <td> GND </td> </tr> <tr> <th> 19 </th> <td> </td> <td> EMU4 </td> <td> GND </td> <td> </td> <td> NC / DBGACK </td> <td> </td> <td> NC </td> </tr> <tr> <th> 20 </th> <td> </td> <td> GND </td> <td> TRACEDATA[3] </td> <td> </td> <td> GND </td> <td> </td> <td> GND </td> </tr> </table> 10.10" (2.54mm) pin and row pitch.

TI has several standards already in use. One particular area where significant work has been done is the high speed tracing connectors. This is being driven by technology changes and the changing needs for debug. * MIPI has a recommendation for a high speed 60 pin trace connector which can provide the flexibility needed for future tracing needs. The recommended connector is the Samtec [QSH-030-01](https://www.samtec.com/technical_specifications/overview.aspx?series=QSH) (PCB/Target) and [QTH-030-01](https://www.samtec.com/technical_specifications/overview.aspx?series=QTH) (Cable/Emulator). * Pin mapping for the 60 pin MIPI connector is in the [MIPI Connector recommendation](https://mipi.org/docs/MIPI_TD_connectors_recommendation_v01-00-00.pdf) document. * The [IEEE1149.7](https://processors.wiki.ti.com/index.php/IEEE_1149.7) does not require a specific connector. Instead, it will simply have the TMS pin become TMSC. When it becomes TMSC, the pin will be bi-directional instead of uni-directional. # Adapters Please check the [JTAG Adapters](emu_jtag_adapters.html) page for details and models available # FAQ ### Q: What are the EMU0/1 pins used for? * A: The EMU0/1 pins can be used for cross-core triggering (ex: one device halts and signals the others to halt, see [Advanced Event Triggering](https://processors.wiki.ti.com/index.php/Advanced_Event_Triggering) or, in some selected devices, these pins are used for [Wait in Reset](https://processors.wiki.ti.com/index.php/Wait_in_Reset) and transfer instrumentation and trace information. Please see the device datasheet/TRM for details. ### Q: What are the EMU2-x pins used for? * A: These are reserved for high speed instrumentation information and trace information. ### Q: What is the difference between the TI 20 pin connector and the ARM 20 pin connector? * A: The TI 20 pin connector is physically smaller than the ARM 20 pin connector. Becuase it uses a simple "stake" connector, it should also be inexpensive. The TI 20 pin connector has additional EMU2, EMU3, and EMU4 pins, which allow it to carry instrumentation data that are available on selected devices. The TI 20 pin connector also features a [System Reset (Emulation)](https://processors.wiki.ti.com/index.php/System_Reset_%28Emulation%29) pin. ### Q: Do I have to use the ARM 20 pin connector to be able to use Adaptive Clocking? * A: No. Adaptive clocking has to do with the generation of of the clock signal based on the return clock. Your debug probe needs to support this feature, or an adapter is needed. See the section solutions of the [Adaptive Clocking](https://processors.wiki.ti.com/index.php/Adaptive_Clocking#Solutions) page. The header just needs to have a RTCK and TCK signal. ### Q: Which connector should I use? * A: Check the section on types of JTAG headers per device family on the [XDS Target Connection Guide](emu_xds_target_connection_guide.html#types-of-jtag-headers-per-device-family). ### Q: What do I need to do if I have a device with an ARM 9 or ARM 11? * A: These ARM devices require adaptive clocking. Please check the Adaptive Clocking section on the [XDS Target Connection Guide](emu_xds_target_connection_guide.html#adaptive-clocking) ### Q: What is a Scan Path Linker? * A: The Scan Path Linker (SPL) is a TI device that is used to configure JTAG scan paths, most often those that connect a motherboard to multiple daughter cards. (This is not the same as the ACT8990 Test-Bus Controller (TBC) device). The scan path linker is used to handle plug-in cards dynamically without breaking the scan path, by reconfiguring the scan path as needed. In general, it is useful whenever your board is in a situation where the scan path can be dynamic, such as during development, when, perhaps not all of the devices on the scan path are populated yet. The Scan Path Linkers ACT8997, are members of the Texas Instruments SCOPETM testability integrated-circuit family. This family of components facilitates testing of complex circuit-board assemblies. These devices also provide buffering of test signals to reduce the need for external logic. For additional information on these SPL devices, please refer to their product pages: [SN74ACT8997](https://www.ti.com/product/sn74act8997) and [SN54ACT8997]([https://www.ti.com/product/sn54act8997). ### Q: Does the TMDSADPEMU-20T map the reset line from the ARM connector to the compact 20 pin TI target connector? Also, what pins are buffered? * A: This adapter translates from ARM 20 pin and TI 14 pin debug probes to compact 20 pin TI target cards. (nRESET) Pin 15 on the compact 20 pin TI target connector is connected to pin 15 of the 20 pin ARM target connector.
