Details:
It is apparently not possible to include both the fuses and global variables
in the same elf file.
When using something like:
FUSES =
{
.low = LFUSE_DEFAULT,
.high = HFUSE_DEFAULT,
.extended = EFUSE_DEFAULT
};
and global variables I get this linker error:
avr-gcc -Os -Wall -std=c99 -mcall-prologues -mmcu=atmega168 -I.
-L/usr/lib/binutils/avr/2.18/ -Wl,-Map,mcrt.map -lm mcrt.o -o mcrt.elf
/usr/libexec/gcc/avr/ld: section .bss [0000000000000580 -> 0000000000000588]
overlaps section .fuse [0000000000000580 -> 0000000000000582]
/usr/libexec/gcc/avr/ld: mcrt.elf: section .bss lma 0x580 overlaps previous
sections
make: *** [mcrt.elf] Error 1
I've reproduced this with other targets like the attiny2313, so it should not
be device-specific.
