TM4C1237E6PM: How do I debug Tiva processors with Segger J-Link using SWD instead of JTAG

Part Number: TM4C1237E6PM
Other Parts Discussed in Thread: SEGGER


I have a board with a Tiva processor that I am trying to debug using a Segger J-Link Plus device in SWD mode.  Unfortunately, CCS gives me a 'Cortex_M4_0: Error: Stat [ JLINKARM_IsHalted() call ] failed!' error when I try to debug.

I know the J-Link connection is good because I can program/erase the Tiva processor through Segger's J-Flash utility.  Here is how I have the Tiva connected to the 10-pin ARM programming connector.

My guess is that the J-Link is using JTAG mode instead of SWD mode, so I was wondering if there was a way to have CCS tell the J-Link to use SWD mode.

I found this (ccxml file view in CCS 8) on your E2E forum:

Unfortunately, this is what I see in my CCS version 11:

Is there a way to enable the JTAG/SWD selection field in the CCS 11 ccxml editor window?

Thank you
