RE: Debugging blinky_example in eclipse

I figured out the problem. Segger had a bug in v4.86 of the JLink software. I finally noticed a bunch of warnings in the JLink GDB Server window and found some information on Segger's forum. See discussion here: forum.segger.com/index.php

Summary: If you see this warning: "WARNING: Unknown packet received: "qXfer:threads:read::0,fff" then update the Segger software to v4.86a

That solved the problem for me and now when I press pause it correctly shows me the disassembly and highlights a line in main.c.

The other interesting thing is that in my debug configuration, I have it set to put a breakpoint at main and that works. If I have that enabled when I press debug, it stops at main. If I don't have that enabled and I press debug, the LEDs just start blinking immediately. So that is clearly using a different way of finding main.c
