Re: [Mspgcc-users] msp430x1612 header

[Peter Bigot]

The x variants were an early attempt to simplify identifying processors
where part number variation did not affect the compiler, at a time when
the MSP430 product line was quite limited.  Introduction of additional
processor families broke those assumptions, particularly in the need to
vary the addresses and presence of different peripherals.

In 2013 when I last updated msp430mcu (may not have been released) there
were north of 450 distinct chip IDs that affected code generation or
peripheral address.  The generic ID originally spelled msp430x16x
covered six of them.

[Norrathep Rattanavipanon]

Thanks I just found out that I need to include periph.x. Just curious is
there any difference for x1612 vs f1612 in terms of hardware configuration?
Or is x1612 just renamed to f1612?

There should be a linker script available as well in the same location.
If you have given the compiler the path to that directory it should find it.

-I /usr/ti/gcc/include

Is what I use.

TI moved a lot of information, like device register addresses, from the
.h files into the linker scripts some time ago. You should use the
provided linker scripts and they will resolve symbols like WDTCTL.

Re: [Mspgcc-users] msp430x1612 header

[Norrathep Rattanavipanon]

Thank you so much for your help, David. Now it compiles perfectly past that
point but I run into another issue (I'm not sure if this is the right place
to post please let me know if its not):

/usr/lib/gcc/msp430/4.6.3/../../../../msp430/bin/ld: cannot represent
machine `msp:110'

I put the following in the linker script - link-MSP430x:

OUTPUT_FORMAT("elf32-msp430","elf32-msp430","elf32-msp430")
OUTPUT_ARCH(msp:110)
,,,

And it compiles using the following command: msp430-gcc -T link-MSP430.x
 -mmcu=msp430f1612 ...

Then, I tried changing OUTPUT_ARCH(msp:110) to OUTPUT_ARCH(msp430). But I
get a lot of undefined references:

/usr/lib/gcc/msp430/4.6.3/mmpy-16/libcrt0.a(__watchdog_support.o): In
function `__watchdog_support':
/build/buildd/gcc-msp430-4.6.3~mspgcc-20120406/./gcc-4.6.3/gcc/config/msp430/crt0.S:105:

Thank you for your help.

Identify a specific part: -mmcu=msp430f1612
