I asked this a while back on the old Keil forum, but got no reply.
So perhaps the Cortex-M experts can help?
Segger support Monitor-Mode Debug (as opposed to Halting Debug) for Cortex-M using their J-Link:
I have used it with Nordic devices - where it is invaluable for application debugging while the BLE stack is running:
However, as far as I can find, Segger is the only one to have an implementation that uses it.
So the question is: Is anyone aware of any other implementation?
I guess it could be that other implementations use a different name - so I'm googling the wrong term?

Or perhaps there is a better section of the forum?
If only Segger offers this, why not use JLink then?
That's the question: is it only Segger - or is there any alternative?
It seems surprising that even ARM don't do it on their own tools!
run-mode debugging is common on Cortex-A with Linux. But actually I did not know Segger offers this. I use a variety of debuggers. But this feature is new to me.
I know that Lauterbach and iSystem have monitor programs. If they can be used together with the JTAG/SWD debugging ?
Would be interesting to know.
Maybe contact your preferred debugger-vendor ;-)

Yes - that's what I've found in googling this.

I have - see the earlier links!

No specific debug probe implementations, though.
