Answer 1

Following workarounds worked with the same problem using ATMega 168P on Atmel Studio 7 with Atmel-ICE.

1. Assembler

Insert the following assembler code where you want your breakpoint:

asm("break");

Please note, this is a really ugly solution and not suitable for all situations. It only works with DEBUGwire and makes your program stop in any case, even if no programmer is attached.

2. Create new project

Creating a new project at a different location helped as well. I copied all the required files to the new folder. The new location has a short path (C:\atmel\project...) and contains no spaces, no umlauts etc.
