Re: [Mspgcc-users] Mspdebug: "prog" programs vectors, not program code

Hello MarkoC,
To rule out a problem with the ELF file (it looks like it is OK from
the prog output) use the msp430 binutils to disassemble:
msp430-objdump --disassemble main.elf
That should confirm you have some valid code in your ELF.
The flash offsets seem correct for the device you are using.
As you seem to be able to write the vectors (segment 0) perhaps you
could change your .ld file to locate the code in segment 2 (0xfa00), I
know it is not a perminant fix but it should give you more of an idea
of what is wrong.
Benjamin.
