The TI EK-TM4C1294XL is a Texas Instruments evaluation board, with a TM4C1294NCPDT MCU (Cortex-M4).
Connecting via J-Link
The EK-TM4C1294XL comes with a standard 9-pin Cortex-M JTAG/SWD connector (U6) that can be used to connect a J-Link to the TM4C1294 MCU on the board. TP2 of the board is connected to pin 3 of U6 and must be connected to GND to allow external debugging. We recommend to use the SEGGER 9-pin Cortex-M adapter which makes sure that pin 3 will be connected to GND.
