@F.N Don't know. Things have chaged since 'April 8, 2008' though. The toolchain has entirely different major versions (the first digit of the version number). Under water avr-gcc calls avr-as for you.

| Nov 16, 2013 at 20:33 | comment | added | jippie | According to the documentation, this is the way it works. You want the C-preprocessor invoked, then call gcc. | |

| Nov 16, 2013 at 20:29 | comment | added | F.N | Yes i saw it. I compiled it , linked it and tested it . Led worked. Thank you very much. So the problem is in the assembler but do you think that there is a way to fix it or not ? | |

Fair enough, I removed the last rjmp. The main label is a required part of the program, if you remove it you get receive an error message. Normally that is the where the main program is located.

| Nov 16, 2013 at 19:23 | comment | added | F.N | OK. the object file now created but why all these happens ? I cannot understand. Also in your code the rjmp to main will never be executed because there is init's infinity loop above. Btw i cannot upvote because i am new user and i don't have reputation. | |

| Nov 16, 2013 at 19:02 | comment | added | jippie | Copy the exact source as in my answer and work from there. My proposed source builds on my system, otherwise I couldn't show you the disassembly listing. | |

Yes. I have already try the .S but once again it returns me an error and it doesn't create the object file. ledON.S: Assembler messages: ledON.S:8: Error: number must be positive and less than 32 such errors i believe that means that the I/O register is not editable.
