what's the standard way to manage the core dump and therefore the
post-mortem debug?
For most embedded systems I know, core dumps are useful on the developer
desk and in the testing lab. For analyzing field post-mortem (where it
is feasible), use a custom fault signal hander in your app to catch the
relevant information and save it.
If you're interested in a tutorial in doing this, I'm giving one at this
year OLS. Or you can just check out the slides and example code here:
http://tuxology.net/lectures/crash-and-burn-writing-linux-application-fault-handlers/
For my experience it could be useful to have a mechanism to have
little dump image (only some information) to store it in flash and
maybe to have an hook (or something like this) for each application to
customize the dump information. What do you think about it?
That's exactly what a custom fault signal handler does :-)
Cheers,
Gilad
