[En-Nut-Discussion] I have successfully compiled and debugged with symbols!

I use the same environment, except Ethernut-4.0.2 and AVRJTAGICE_MKII

I have tried this as well and the NutOS code compiled well. Then, when 
trying to compile my own code it complained that:
--------------
jose at aut-090 /cygdrive/c/ethernut-4.0.2/nutapp/PEM
$ make clean
../Makedefs:10: c:/ethernut-4.0.2/nut/app/Makedefs.avr-gcc-debug: No 
such file or directory
../Makerules:4: c:/ethernut-4.0.2/nut/app/Makerules.avr-gcc-debug: No 
such file or directory
make: *** No rule to make target 
`c:/ethernut-4.0.2/nut/app/Makerules.avr-gcc-debug'.  Stop.
--------------

So I just got inside c/ethernut-4.0.2/nutapp/ and copied the 
Makedefs.avr-gcc and Makerules.avr-gcc adding the "-debug" at the end of 
their names. Then it worked.

So, basically I can see now the NutOS code in my debugger, but now I 
have another problem: I cannot go "step by step" in my code; when I 
press the "next" button in AVR Studio, it goes all dooooown to the 
deepest guts of the NutOS. I will give more details in a new mail.

Thanks!
