Hi Peter,
I found another issue, I think with binutils this time.
I have multiple object files, linked into a final elf file, when I do the final
link, the final file looses the flag saying its MSP430X architecture. This
causes objdump to disassemble without the extended instructions.
the header from the intermediate files is (msp430-objdump -x output)
main.o: file format elf32-msp430
main.o
architecture: msp430:430X, flags 0x00000011:
HAS_RELOC, HAS_SYMS
start address 0x00000000
>From the final main elf file,
main: file format elf32-msp430
main
architecture: msp430:430, flags 0x00000112:
EXEC_P, HAS_SYMS, D_PAGED
start address 0x00005c00
This is binutils version
peter@shed:~/msp430/test$ msp430-ld --version
GNU ld (GNU Binutils) 2.21.51.20110205
gcc version
peter@shed:~/msp430/test$ msp430-gcc --version
msp430-gcc (GCC) 4.5.2
Probably not that hard to track down, but I don't know where to start.
Cheers,
Peter Jansen
