I am working on a PC running CentOS as its operating system.
I also work on a embedded with the same OS.

On my PC, I succeeded to create a core dump file on segmentation fault by changing:

  1. core pattern
  2. core_uses_pid
  3. ulimit -c unlimited
  4. sysctl -p

But on the embedded system nothing works – the core dump is not generated! What could be the reason?

If it matters, the application that I would like a dump of is written in C++.

What can I do to get a core dump on the embedded system?

I’ve made a little crash program, and core dump is generated from the crash program but not for the one i need !!!
So the problem is not on the O.S, but with the specific program.
I discover that we strip -g executable/library files before sending them to the embeded system.I did the same for my crash program, and this one still produce core dump.

    Are you certain the kernel on your embedded system supports core dumps? The feature can be disabled in the kernel build (ref), in which case you may have to fake it yourself using something like google-coredumper.
