I hadn't gone all the way to Level 0 optimization mainly because then the example code wouldn't fit in the allocated ROM space.

Hi,

This will happen when you have high optimization set. For debugging purposes, I always recommend using -O0 to avoid compiler magic. See this thread for more info: devzone.nordicsemi.com/.../

Cheers, Håkon

Strange. The only other thing I can think of is if the compiler determines that the code has no effect and therefore does not compile it:

dfu_start = false; No code because the location is zero initialized.
app_reset = (NRF...); Set the variable to the determined value.
if (app_reset) No instruction; does it mean app_reset is always true?

If you look at what nrf_gpio_ functions there might be a similar explanation.

Thanks, but no, the debugger is not in simulator mode.

Are you running the debugger on target or are you using the simulator? Could be that the debugger is set to simulator, in which the IO registers don't do anything.
