CCS/CC3220SF-LAUNCHXL: Unable to use cc3220SF device in 2 wire swd mode.

Part Number: CC3220SF-LAUNCHXL
Other Parts Discussed in Thread: UNIFLASH, CC3220S, CC3220SF

Tool/software: Code Composer Studio

Hello,

I was trying to test debug using 2 wire SWD method.

The interesting thing when I tried to test Connection in Target configuration on a brand new board out of the box. It was successful.

Then I flashed network_terminal example from SDK. Then the test connection failed.

Please correct me if I am wrong. In order to debug the application using 2 wire SWD.

Set SPO to 101, then flash the binary using uniflash.

Set SOP to 001 then start the debug session from CCS.

Is there any setting during compile time that I need to do for SWD mode to work.

I was able to test SWD with CC3220S...it works perfectly fine. Are ther any additional settings required for CC3220SF.

Below is the COnfig for cc3220sf that I am using.
