I'm struggling to enable core dumps in Ubuntu 14.04 LTS (ARM) running on an nVidia Jetson TX1 SBC. I've done all of the usual stuff, including suggestions from here and here. There is plenty of space on the root filesystem, which is writable. The application does not have the suid bit set. I have also disabled ubuntu's "apport" service. Here's what I've set:

/etc/security/limits.conf:

*               soft    core            unlimited
*               hard    core            unlimited

Kernel core settings:

$ cat /proc/sys/kernel/core_pattern
core
$ cat /proc/sys/kernel/core_uses_pid
1

Output of ulimit:

$ ulimit -c
unlimited

And after starting my process:

$ egrep "Units|core" /proc/$(pgrep my_app_name)/limits
Limit                     Soft Limit           Hard Limit           Units
Max core file size        unlimited            unlimited            bytes

But no cores are generated when the application segfaults, aborts, or has a floating point exception. What have I missed?

The only thing I can see that could cause that would be that the current working directory of the application is not writable to the running user.
