arm-none-eabi/bin/ld: region RAM overflowed with stack

[Jim]

I'm getting this error, but oddly it's coming up somewhere in the MIDDLE of my build, and not always the same point.

I have modified the HEAP size to be 0 as I don't do any malloc-ing. But, I did that in gcc_startup_nrf51.s, which isn't compiled yet at this point in the build (nor is main.c).

I've started this particular project from the HRM example, which I am able to build under eclipse when the wind is blowing in the right direction.

I've attached my build output, showing the error coming up early in the build, and my .map file, which I am under-qualified to interpret properly.

Anyone got an idea?

OK, I've resolve the mystery of the out-of-order linking. It's actually an Eclipse issue. The Eclipse console cannot properly interleave stdout and stderr from the build. I guess that's hard to do. I am resisting challenging that notion with all my might.

So, if you get confused by Eclipse build output, try breaking the build up with some intermediate targets.

Silly silly silly.
