in other tools i've seen bss_Start. but i have not read anywhere that is exists in avr-gcc.
it does call .do_clear_bss_start
There are no missing files. Everthing builds fine, i simply do not how to reference the end of the .bss.
in other tools i can do int var = bss_end;
or a similar nomenclature is generally valid. I've read the compiler, linker, and the make manuals but did not see anything about referencing the end of the bss.
The map file shows the linker script using PROVIDE (__bss_start, .) Everything i have tried to reference this has produced an error.
If anyone has referenced the end of the bss with avr-gcc, I would appreciate the requirements(arguments, example etc) A citation in the documentation would be great.
