Thanks for the detail.

Can you attach the below log file, in case this reveals anything at the OpenOCD Layer:
Code
Select All
ebug/Blink.ino_DebugOpenOCD.log

We will release a fix with the below present soon, I had confused my SWD and HLA_SWD's

If you add the below entry to the Local Board.txt in the project it will resolve this before the release is available:
Code
Select All
tools.stlinkv2.server.boardCmd=-f "interface/stlink.cfg" -c "transport select hla_swd;"

Thanks for the confirmation and working through this with us.

The latest release on the board below (20.09.10.23), now has all of these fixes applied so the overrides from board.txt should no longer be needed once updated:
