Ok Oleg,
Sorry for this mistake again.
I posted a patch to binutils-current which defines some new constants:
__XXX_what_rom (XXX = data|noinit, what = start|end) which point to the ROM
locations. Use them instead. So, this patched linker will appear hopfully in
a week in binutils tree. So, pull it from there and rebuild.
The patch is below.
If you do not want to wait, add the following lines to _all_ (sorry :) linker
scripts and have fun (at the bottom before closing '}'):
PROVIDE (__data_start_rom = _etext) ;
PROVIDE (__data_end_rom = _etext + SIZEOF (.data)) ;
PROVIDE (__noinit_start_rom = _etext + SIZEOF (.data)) ;
PROVIDE (__noinit_end_rom = _etext + SIZEOF (.data) + SIZEOF (.noinit)) ;
cheers,
~d
