Enable core dump on Linux 2.6.35

I'm running kernel 2.6.35 on a custom embedded device (ARMv7). I'm trying to get a core dump but it appears core dumps are disabled. My kernel config can be found here: https://pastebin.com/XXZ8YyaA My test application is the following: int main() { return 1/0; } I expect the following: Floating point exception (core dumped) But instead get this: Floating point exception Meaning core dumps are disabled. How can I enable them for my platform? It looks like the option to toggle functionality in the kernel CONFIG_COREDUMP wasn't added till kernel version 3.7 . Is it not always enabled in previous kernels? # ulimit -a -t: cpu time (seconds) unlimited -f: file size (blocks) unlimited -d: data seg size (kbytes) unlimited -s: stack size (kbytes) 8192 -c: core file size (blocks) unlimited -m: resident set size (kbytes) unlimited -u: processes 1710 -n: file descriptors 1024 -l: locked-in-memory size (kbytes) 64 -v: address space (kbytes) unlimited -x: file locks unlimited -i: pending signals 1710 -q: bytes in POSIX msg queues 819200 -e: max nice 0 -r: max rt priority 0 -N 15: unlimited # ./crash Floating point exception
