Welp, not a lot of error message to go on here 
In any case though, in your previous full sketch, it seems like it does generate the .elf file and then just fails in the post checks (because the full 32K is not available due to a boodloader I assume). Which means you should be able to do the following:
- Let GCC generate a map file (Generate a .map file - #8 by Krishna_Chaitanya)
- throw that in amap.
