I have a EK-TM4C123GXL LaunchPad includes TM4C123GH6PM. I want to debug that with BLACKHAWK XDS200 or BLACKHAWK USB100v2.

I am using CCS v11.xx and Uniflash programs. My connections are like that;

Debuggers JTAG 5 pins(TMS,TCK,TDI,TDO,nTRST) goes to Boards 5 pins correctly. Debuggers GND goes to Boards GND. Debuggers TVD pin goes to Boards 3.3V. Boards EXT DBG pin goes to GND like datasheet. Supply switch states is "DEVICE"

Debuggers seen by programs easily, There is not any problem.

Boards voltages are correct.

But Even though I am sure of every connection, I still get the -183 (broken cable) error. Debugger can not see processor and can not debug it.

I tried with 2 different similar boards but results is same. Moreover I can debug with internal debug interface without any problems.

Considering all this, what could be the problem?

I drop the photos example.

I have 2 more questions

1. I searched for driver software for debuggers, but I think the drivers are loaded together with CCS (I am using v11.2). Do I need to load another software/driver?
2. Should the EXT DBG pin be pulled to GND when programming the board with a debugger or when using the board as a debugger?
