Correction for Test 3: msp430-gcc core.a main.o -mmcu=msp430g2452 -Wl,-Map=hello.map -o hello.elf should read: msp430-gcc core.a foo.o -mmcu=msp430g2452 -Wl,-Map=hello.map -o hello.elf

Test 2: when I create an archive core.a that holds foo.o with: msp430-ar rcsv core.a foo.o and then link the final elf file with: msp430-gcc core.a foo.o -mmcu=msp430g2452 -Wl,-Map=hello.map -o hello.elf All again is blinky blinky. Test 3: The problem surfaces when I create an archive core.a that holds main.o with: msp430-ar rcsv core.a main.o and then link the final elf file with: msp430-gcc core.a main.o -mmcu=msp430g2452 -Wl,-Map=hello.map -o hello.elf All is dark. I ran the same test with a simple "hello world" compiled for x86 using gcc and ar under cygwin and all is fine in all 3 cases. Any idea why this does not work for msp430? I looked at the linker scripts but that only resulted in more darkness.
