Re: [avr-gcc-list] big string into the ROM

[Keith Gudger]

If you've tried the -T linker option, as Ned suggested, and you still get
this problem, you may need to recompile your string file and put the
string information into a named section, which you will need to reference
in the linker script, too.

Did you create your linker script from the one used by default?  You can
get it by typing "avr-ld --verbose > linker.script", and then you'll have
to edit the "linker.script" file to remove some junk from the -ld output.
Then add the suggestion below in the appropriate place, and include it by
modifying your makefile's linker flags to include -Tlinkder.script
