nRF52 Debug in Keil

[tcbriese]

I'm a hardware/beginning software guy just getting the nRF52 up and running using the Keil uVision5 tools. I go to debug either the blinky project or heartrate project and I can't seem to step through code/set breakpoints.

I can stop and run the code, and then confirm that the program halts and continues as expected.

Anyone know the reason why stepping/breakpoints wouldn't work?

It was just the optimization level was set to 3 instead of 0 in the C/C++ options for the target. I can now set breakpoints/debug.

For me it works pretty well. Sometimes I have to do a Debug->Start/Stop debug session, but otherwise stepping and breakpoints are working correctly. I am using PCA10040.
