This has been tested with Nut/OS Version 2.5.2, AVR-GCC 3.2 or ICCAVR 6.26 and AVR Studio 4.04.
Works with AVR-GCC object files only, not with elf files or coff files created by elf2coff. No variable watch with GCC, only ICCAVR offers this feature.
Press cancel when AVR Studio requests GCC's gcrt1.
Don't forget to modify the Makefile when using GCC. Uncomment line with compiler option -g and -O0.
AVR Studio may crash while debugging Nut/OS. However, debugging your application is typically no problem.
