I just tried that, but it unfortunately it doesn't seem to have any effect. $ msp430-elf-gcc -mmcu=msp430g2231 -Os -static -Wall -Wextra simple.c -o simple.elf -Wl,-gc-sections /usr/lib/gcc/msp430-elf/4.9.0/../../../../msp430-elf/bin/ld: simple.elf section `.bss' will not fit in region `RAM' /usr/lib/gcc/msp430-elf/4.9.0/../../../../msp430-elf/bin/ld: region `RAM' overflowed by 14 bytes collect2: error: ld returned 1 exit status /Emil ------------------------------------------------------------------------------ CenturyLink Cloud: The Leader in Enterprise Cloud Services.
