I think this is referring to J-Link Monitor Mode debugging (or similar solutions). Please have a look at this tutorial on Github for details on how to use this on the nRF52 series ICs.

Hi, Jorgen,

Real-time debugging will allow interrupts to execute to completion in real time when breakpoints are set
in Thread mode or lower priority interrupts. This enables the developer to set a breakpoint and single-
step through their code without a failure of the real-time event-driven threads running at higher priority. For
example, this enables the device to continue to service the high-priority interrupts of an external controller or
sensor without failure or loss of state synchronization while the developer steps through code in a low-priority
thread.

But how to set breakpoints in Thread mode or lower priority interrupts? it don't say.

Regards.

Hi,

What exactly do you mean by "Real-time debug"? Setting the Optimization level to None or -O0 is recommended when debugging, as this is the mode supported by all compilers/IDEs. You might also use Debug (-Og), if using GCC/SES. See -Og on this page.

Best regards,
Jørgen
