[avr-gcc-list] SRAM Usage

[Peter Bosscha]

Hi,

 

I'm using the windows port of AVR-GCC (Volker Oth) and have completed a few projects.

Only recently I've discovered that the linker seems to be rather generous with SRAM.

Looking at the map file I find that between modules of a project there is always a fill until the next 0 nibble, I could define a single byte in a module which then actually wastes another 15 bytes. The same happens when I mix bytes and arrays of chars, again there is an allignment, this time within the module,  to the next nibble.

 

Anyone any ideas ? I would expect that one can adjust the linker to do this differently ?

 

Thanks in advance
