Looks like it crashes before reaching main:

I've changed timer to 2 and rebuilt and reloaded app - no changes.

That would be nice. It was quite puzzling to search for these definitions
scattered all over the sources.

Sure. I loaded it while was playing with slinky example. And loading slinky
instead of lora app works fine.
