I have never actually debugged with it, but maybe the previous programmer did. When I click Flash in the tool bar, it does not program the development board, it programs our custom made board for our instrument.[/quote] If you are currently using the DK-TM4C129X board as a programmer for an external custom board then you would need to first remove any wires between the two boards and also restore J3 jumper on the DK board to its original settings so you can debug the target device on the board itself. Refer to the user's guide for details. 2.1.4 Debugging and Programming • ICDI: The DK-TM4C129X has a built in debugger, which can be used by connection to a computer using the included USB micro-B to USB-A plug cable from the microUSB-B connector (J4) located in the upper right of the board to a USB port on your computer. The on-board ICDI can also be used to debug external boards using the ARM standard 20-pin connector (J1) and pulling all the shunts from J3. • External debugger: an external debugger can be used through the ARM standard 20 pin connector J1.
