Try this, do a full flash erase first. Then try your project again, see if it stop in Reset_Handler. You can use the nRFProg to erase all.

No I had not added the -g3 compiler option. But I just tried, and no difference :(

The debug symbols appear to be missing. Did you add the -g3 to the compiler options? Debugging options

I never hit the Reset_Handler if I set a breakpoint in gcc_startup_nrf51.S Please check edit in the question. :)

It is not require to have all the stuff there. Bare metal, what you need are CMSIS lib (has precompiled lib), add reset vector source and linker script and of course the require Path. You can leave the rest of it out. The startup code is compiled in the CMSIS lib. All the projects has been upgraded to Mars. You'll need to create yours on Kepler.

What is a "Mon reset"?.. I'll look at the new tutorial later today.

I am using Eclipse Kepler, and I'll try setting a breakpoint in the Reset_Handler in startup_nrf.S later today. I've seen the blog, and tried it out, but I would like a bare metal project to begin with, and then build my own structure :)

Are you doing a 'mon reset' after you load the files, before continue?

Also, we released a new tutorial for development using Eclipse now. devzone.nordicsemi.com/.../

Try to put a breakpoint at the beginning of Reset_Handler function, see if it stops there.

You can also follow this blog for Eclipse GCC dev. It has example projects you can use. All pure Eclipse projects no make files.

BTW.: Eclipse Luna has bugs in debug mode. It does not work properly. You need to get Mars version.
