ITM Debug with SWV H755

I am unable to get ITM debug working via either CubeIDE or Cube programmer. 

 

I have checked the sysclock matches the sysclock configured for the system.

I have tried various limits and auto for the SWV clock.

I have enabled SWV in the debugger config.

In cubeIDE I see no data (port 0 is enabled on the ITM Data Console).

Looking at the log in cubeprogrammer I can see that SWV connects and then disconnects instantly when I click Start on the SWV tab.

Logging and analysing the signals I can see that SWDIO drops at about this time.

Any ideas?

What hardware are you using? Is this a dev board? If so, which one?

What ST/Link debugger/programmer are you using?
