Other Parts Discussed in Thread: TMDSEMU560V2STM-UE
Tool/software: Code Composer Studio
I am running CCS version Version: 7.2.0.00013. We are locked into that version for this project. I am connected to an XDS560v2 STM for flash/debug. We are utilizing a TMS320F28335.
This setup had been working with two different board designs and multiple copies of those designs and suddenly began failing for all boards with the following message:
We saw this problem one other time and it seemed to go away after switching between release/debug build configurations. Nothing else changed as far as I know. We were simply browsing around in CCS looking for something that might be wrong, happened to switch between build configs and, whether this was the direct cause or not, it issue went away right after this activity.
What we have checked so far:
1) Attempted programming 3 different boards. Although they use the same part, they are two completely different designs. All boards were working previously. I am currently unable to program or have a successful connection test with any of them.
2) Rebuilt workspace with current version of projects.
3) Rebuilt workspace with previous revision of projects.
4) New USB cable.
5) Programming with computer with running on battery.
6) Confirmed the code security password values in CCS are set to all FF. Read the values back from one of the boards via CLI and confirmed they were all set to FF.
7) Power supply looks ok. Scope trace attached showing Vcc, EMU-0, EMU-1, and _TRST. This is triggering on _TRST during a programming attempt.
We have a new XDS560 and cable on the way and we will try those out as soon as they arrive.
Finally here is the log from a connection test:

An error occurred while hard opening the controller.
-----[An error has occurred and this utility has aborted]--------------------
This error is generated by TI's USCIF driver or utilities.
The value is '-231' (0xffffff19).
The title is 'SC_ERR_PATH_IR_MEASURE'.
The explanation is:
The measured length of the JTAG IR instruction path is invalid.
This indicates that an error exists in the link-delay or scan-path.
