Monitor Mode Debug (MMD) with Keil uLink ?

[awneil]

See: http://www.keil.com/forum/63929/

Everything here refers to J-Link, eg devzone.nordicsemi.com/.../a-working-demo-of-monitor-mode-debug-mmd-on-sdk-15-please

and Google only seems to find stuff related to J-Link - but can a uLink do it ?

Hi,

Monitor Mode Debugging is J-Link-specific feature. I do not expect it to work on other debuggers, and if it should, the license will most likely not allow you to do that.

I'm not aware of equivalent functionality for uLink debuggers, hopefully someone on the Keil forum can help you answer this question.

Best regards,
Jørgen

No, I don't think that's (entirely) true - it is a facility of the Cortex-M (except M0) CPU core?

But it does seem that Segger are the only ones to have the support to take advantage of it

Exception number 12 in Cortex M4 Vector table is "Reserved for Debug", but I was referring to Monitor Mode Debug as Segger's specific implementation making use of this feature for J-Link debuggers.
