Hello, recently i started programming AVR mcus and ran in to few questions regarding compilation and linking. I am a looking for some resources that talk about linker files, assembly and etc. Maybe some one who has expirience with this topics can point me int he right direction.
This goes through the basics:
https://www3.ntu.edu.sg/home/ehc...
Note that the techniques described are common for most compilers and not specific to AVRs. There is a wealth of information about gcc and how it works.
Regarding the specifics of avr-gcc, maybe look here:
https://www.nongnu.org/avr-libc/
and here:
https://www.microchip.com/webdoc...

There used to be a great diagram showing all the build steps and how they relate. I've posted it here a couple of times. I tried googling but could not find it but did find...
and also
which actually seem very similar anyway.
I was actually more curios about the linker files, and the documentation for avr-gcc. i dont know if i unlearned how to google, but seems it is hard to find good pice of information

Some of what it sounds like you're interested in is not so much "avr-gcc" as just plain "gcc", so you need to back up and find documentation for gcc, rather than looking in the documentation for avr, that will tend to be geared toward the specifics of the embedded environment.
The larger gcc is very generic. For example http://www.scoberlin.de/content/media/http/informatik/gcc_docs/ld_3.html

Do you mean linker scripts ?
ie, the file that tells the linker how to lay out the code & data in memory?

Is this the one you were looking for:
https://www.avrfreaks.net/commen...
In looking for that, I also found:
and
https://www.avrfreaks.net/forum/atmel-studio-4-problem-looking-elf-file
which links to another of your posts using the 1st diagram:

I was actually more curios about the linker files, and the documentation for avr-gcc.
In every installation of avr-gcc/binutils, alongside the binary you should find:
C:\Program Files (x86)\Atmel\Studio\7.0\toolchain\avr8\avr8-gnu-toolchain\doc>tree /f
Folder PATH listing for volume OSDISK
Volume serial number is 00000216 7AF3:B2D0
