If at all possible, ditch IAR, and use GCC or Imagecraft. I have
personally
found the IAR C-Spy to be more a hindrance than a benefit.

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.

I too have had some problems setting breakpoints but I believe that this
is
related to the fact that I'm not actually editing the source from within
Embedded Workbench. I'm using an external editor and makefile to build.
I find that if C-Spy has some source files open and I download some new code
then it doesn't always reload the updated source file. If I close all the
windows and continue stepping through my code then the breakpoints work as
expected.
You say that the whold whing resets, is this because of the watchdog
barking?
Have you tried the other com port?
On our MSP430F149 we're using both com ports and haven't had any
problems
like your describing.

Stephen

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.

Hi John,
Thanks for the reply, I'm still trying to get linux on my laptop, (I
don't understand the installation part about the partitions) but
anyway, I'll try this as soon as I get it running. One more question
though; how do you upload the code in to the msp? And how do you debug,
do you still use Cspy??
thanks,

Martijn,
In the CVS tree (
http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/mspgcc/pyjtag/
<http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/mspgcc/pyjtag/> ), pyjtag
will allow you to use a FET dongle to program parts via JTAG. There is also
pybsl ( http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/mspgcc/pybsl/
<http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/mspgcc/pybsl/> ) for using
the serial port loader on a MSP (I built my own hardware, I dunno what
you're supposed to use as an adapter, normally). These both work pretty
well.
As far as debugging, I use printfs, LEDs, and occasionally the
oscilloscope. I've tried GDB, but I find that overall, I despise it.
However, that's just my opinion. Some people swear by it (I generally
swear
*at* it). Since almost all my projects use the serial port in one form or
another, the printf() (or puts()) debugging works quite well for me.
Incidently, your best bet for partitions is to create a swap partition
that's 1 to 2 times the amount of RAM you have in your laptop, but is at
least 256MB. Make the rest of the disk a single partition, and select
'ext3' as your file system for it. This is the same as ext2, but has
journalling. ext3 is readable under ext2, if you have to take the drive
out, or boot from a floppy, or such. reiserfs works well also, but doesn't
have that luxury.
For drives less than 30 or 40GB, I really don't see the point in
splitting them into multiple paritions.

Hi John,
Thanks for the reply, I'm still trying to get linux on my laptop, (I
don't understand the installation part about the partitions) but
anyway, I'll try this as soon as I get it running. One more question
though; how do you upload the code in to the msp? And how do you debug,
do you still use Cspy??
thanks,
Martijn

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.

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.
