since the recent update to AS 6.1 it does display memory usage for flash and ram automatically at the end of the build. This is nice, but it does not work as i would think it should, at least on UC3. It does report for even the smallest project that the ram is nearly full or even exhausted:
text data bss dec hex filename
9796 0 65532 75328 12640 CLOCK_EXAMPLE11_ASF313.elf
(This is the report for a small ASF demo program with only a few lines...)
Code size extension shows 99% ram usage for this example.
Toolchain settings should be pretty standard.
If you need more information let me know.
