Thank you Marko for the pointer.
On a related note, I noticed today that my simple blinky example
that uses Nordic's peripheral library, along with the mynewt RTOS
seem to be crashing. Logs below:

With this simple blinky app, I was trying to see If I can use the
Nordic's peripheral library along with Mynewt core/Mynewt RTOS.
I mentioned [1], this somedays back in the dev-mailing list.
Questions:
1: How can I debug this further ? I've used gdb, but not much in past.
2: Is such a approach (using Nordic's peripheral library) with mynewt
core is indeed okay ? For example, I was interested in trying out
Nordic's PPI examples, but couldn't find PPI related APIs under,
Mynewt's core repo and hence, thought of using this approach.
Lastly, If someone wants to try this setup, then please follow this [2]
readme; the code is hosted on github.
