[BareMetal] Can't start debug process with ARM GDB 8.0 but all work with GDB 7.7.1

Impossible to start  debugging with ARM GDB (arm-none-eabi) 8.0, code start loading but at the end error dialog is shown:

{code}

Cannot continue debugged process:

Cannot execute this command without a live selected thread

{code}

Note: all work well with same config but runs from command line.

Note: just a replace GDB with 7.7.1 also "fixes" issue.

If any additional info is needed, please ask me.
