With the 1611 (i was using the wrong mmcu)
The result, it's the same.
As Cristopher explains me what go in the .bss.
A curious thing, in the case of the rs274ngc, if i initialize some
variables (large structs), the .data section grows beyond expectations
text data bss dec hex filename
626 18 0 644 284 canon_stand_alone.o
4366 0 0 4366 110e driver.o
54 6 0 60 3c file.o
90 0 0 90 5a math.o
28990 27166 0 56156 db5c rs274ngc.o
for the rs274ngc
before data + bss = 3766
after data + bss = 27166 (26.5 KB aprox)
Why?
