Sorry, the debug.script had an error at the end, updated script attached.
Also, to download using insight, just select Run, Download. The script does the
rest.

Hi All,
gdb-proxy can be confusing and tedious to use, especially for a first
timer.
Things such as having to remember to manually delete flash "before"
doing a download, etc.
Ive created a couple of scripts that make life a whole heck of a lot
easier.
The first script launched gdb-proxy, then gdb/insight.
When gdb/insight exits, it automatically kills gdb-proxy.
The second and thirs I use for my projects, the "debug" shell script
launches gdb-proxy and gdb/insight via the other script, but tells it
the file to debug and forces it to execute a gdb script at startup.
the "debug.script" is a gdb script, the attached one is generic, but I
usually customise it per project. Adding things like macros to dump
on-chip registers symbolically, etc. The main thing it has in it are
the pre-setup option to tell gdb how to best talk to gdb-proxy. The
other thing it has are pre and post hooks on load. The pre hook resets
the cpu, and erases the main flash. (If you also want it to erase the
info flash, just change "main" to "all") after the pre-hook has
executed, the load takes place. the post-hook then does a cpu-reset to
ensure the cpu is in a starting state, after the download has been
completed.
What this means is that from the insight interface, the user no longer
has to worry about deleting flash before downloading. You just select
load, and the script will automatically handle the peculiarities of
msp430's.
Also, dont forget, you must have ppdev loaded for any of this to work.
Just because it isn't dont be fooled into thinking your kernel doesn;t
have it. Log on as root and type
insmod ppdev
then change the permissions of /dev/parport0 /dev/parport/0 to be ugo+rwx
