msp4300 toolchain

G'day,

I'd like to do some development with TI's msp430 processors. As a
starting point I've got the TI LaunchPad which has an msp430g2231.

As best I can tell, there seem to be 3 paths to a toolchain:
1 - crossdev - with an appropriate tuple, for example
a - "crossdev -t msp430"
b - "crossdev -t msp430-none-none-uclibc"
2 - portage to emerge dev-embedded/msp430*
3 - sourceforge's mspgcc project

I could go into the difficulties I've encountered with each of the
above, but I don't want to overload this message and bore everyone.

So the questions are:

Is anybody on this list doing msp430 development/experimentation? Has
one of the above paths been found to work? If so, which one?

Thank you.

David

I'm not sure Linux is relevant for those 16-bit chips, nor uClibc?

I'm not interested in running Linux on the MSP430. My goal is to use
Linux to cross-compile code that will run on the MSP430.

There is a msp430-gcc package in portage. Have you tried that ? I've
once upon a time used a toolchain from:

http://cdk4msp.sourceforge.net/

In the ebuild in dev-embedded/msp430-gcc is the following line:

is_crosscompile || die "Only cross-compile builds are supported"

I'm not sure exactly what it means, but it seems to mean that this
ebuild can only be used when cross-compiling, i.e. when building gcc to
_run_ on the msp430.

I want to build a cross-compiler, i.e. a gcc that will run on my x86_64
and create code to run on the msp430.

someone has sent me a patch to crossdev to add msp4300 support. i'll let you
know when i push a release with it.

crossdev-20111221 should work. if it doesn't, file a bug.

Hi Mike,

I'm looking forward to trying the new crossdev. I've sync'd portage
and have the ebuild. Unfortunately the .xz file hasn't made it to the
portage mirrors.

Thank you.

That line means exactly what you want, i.e. you can only build
msp430-gcc for cross-compiling from your amd64/x86/etc host to an msp430
target.

If you have any troubles building the msp430 toolchain in the tree with
crossdev please file a bug and I'll look into it since I'm the primary
maintainer for the msp430 toolchain on Gentoo.

Thanks,
Tim

Hi Tim,

Glad to make your acquaintance !

With crossdev-20111212, binutil built fine, but gcc stage 1's build
encountered an error in configure. A bug has been filed.

Davvid

Hi Mike,

The msp430 toolchain generated is working very nicely for me and has
been building msp430 executables for several days.

With kernel config updates (to include CONFIG_USB_SERIAL,
CONFIG_USB_SERIAL_TI, and CONFIG_USB_ACM), demo programs are running
nicely on my TI Launchpad.

Thank you for the crossdev update.

Regards,

David
