I always make a separate /home partition. It makes the transition to a
new distribution/clean upgrade alot easier. I agree with everything
else though :>

BTW, thanks for posting the msp430 gcc setup script. I'll give it a
try soon. I've got an Olimex board I want to start playing with under
Linux.

John, brian, Richard,
 
Thanks to all of you, i've got it running now, (RedHat 8.0) I've run
the
script and all are installed and tested. I still need to install the phy
ting but I'll do that tomorrow. My problem was that I was afraid of
losing my windows data. But both systems run fine. Now.
 
B.t.w is there a possibility that I can get access to my winXp partition
(and then copy projects) while running linux? I've still got some
projects for GNU that I'd like to try now??
 
 
thanks,
Martijn

Dear John,
 
Sorry to bother you again with my gcc questions, but could you help me
out again?
 
I've done as you mentioned and have been testing some code on a duff pc
running linux red hat 8.0. but I now would like to do the same while
using Gygwin. Do you have any tips here? Could I still run/use youre
script and compile my files like I would under RH??
 
thanks,
Martijn

Onderwerp: [msp430] Transitioning from IAR V2.10 to GCC
 
Martijn,

    Create a directory on your Linux box, something like /home/msp430.
Save
this script to a file, and then run it with ``sh buildmsp`` (or whatever
you
named it).  This will get all the current sources from GNU and
Sourceforge,
and build the toolchain and MSP430 libraries.

      If you browse Sourceforges CVS tree, you'll see some examples in
the
examples directory.  They should be sufficient to get you started. 

      Remember that when you use the tools, you need to modify your path
to include ``/usr/local/msp430/bin`` (if you're using the ``bash``
shell,
you can type ``export PATH=/usr/local/msp430/bin:$PATH``.  To prove that
you
compile something, you can just create a program that doesn't do
anything,
such as the following:

#include <msp430x14x.h>
#include <string.h>

int main (void)
{
   const char *s = "This is a string";
   char buffer [32];

   while (1)
      strcpy (buffer, s); 
}

Compile this with:

      msp430-gcc -W -Wall -mmcu=msp430x147 -O2 -g -c testfile.c -o
testfile.o
      msp430-gcc -W -Wall -mmcu=msp430x147 -O2 -g -o testfile testfile.o

      msp430-objcopy -O ihex testfile testfile.hex
      msp430-objdump -dSt testfile > testfile.lst

You can then use ``more`` or ``vi`` to browse ``testfile.lst`` and see
some
produced code.  You can then create some code tailored to your hardware
to
blink a LED or something to get started.

      --John

Hi Stephen,

Thanks (John to) the problems I'm having is that for some reason I can
set breakpoint practically anywhere, but in one file, and, yep you guest
it, that's the file that I don't trust. Further if I let It run freely
then after receiving data over one comport the whole thing resets.
Pretty annoying.

Futher John, I've just setup a linux system but I'm new here, I found
some code sample form the SOS which look nice to try, but I don't know
where to start using gnu, have you got any suggestions??


thanks,
Martijn

I've been using v2.10a for about 4 weeks now.

The porting from v1.26b to v2.10a was quite a problem. I found several
bugs
in the io430x14x.h header file. Some serious, some not such a problem.

For example the register definitions for ME2 register were wrong so the
UART
was never being enabled.

The jmpbuf definition is wrong and can lead to variable being
overwritten.


However, I now have my code ported to v2.10a and it's running fine.

What sort of problems are you having?

Have you downloaded the latest header files from the support website?
There
is an update available.

Failing that v2.20a is due to be released on 9th May.

Stephen
