Re: [Mspgcc-users] trouble with the launchpad

[Alex B. <du...@gm...>]

Thanks! All those linker options are currently necessary because I had some
trouble installing mspgcc and without those options it can't find the
includes or linker scripts.

I've now installed the toolchain on another computer, running Linux, and it
works, without any superfluous options! And I can see in the mspdebug
output that it is correctly writing to the reset vectors. Sorry to give you
the runaround with that patch attempt.

So, something about the 2452/2553 linker script or memory map must be wrong
on my OSX installation. Has anyone run into a similar issue?
