Hi,

I am debugging a user application and I have some doubts, and maby someone can answer my questions.

My application produces a segmentation fault, I suppose that a segmentation fault provoke a core dumped, is this true?

If I want to have core dumps in uClinux, as kazuyasu commented in last posts I have to insert the command : ulimit -c unlimited. But where is it in the configuration kernel?, I haven't found.

And my last question is, is the core file created in /proc/sys/kernel?, if not where is it found?

Many thanks
