We have Yocto as our build environment .

Would like to know how and where we can provide this Coredump support .

Answer 1

Start with reading core manual page , you are probably just looking for /proc/sys/kernel/core_pattern .

If your shell does not have ulimit support , you may need to call setrlimit(RLIMIT_CORE) .
