Yes, that's right. You seem to have captured the SIGILL trap.

It looks like the driver crashes while running the dynamic_reconfigure
callback. That happens initially, even if dynamic reconfigure is not
running. I'm not so clear to me what goes on at that point. I'd guess
dynamic reconfigure is trying to send a message, perhaps to register
its service.

I'm not familiar with ARM tools, but given the illegal instruction I'd
take a close look at the way you compiled everything. Perhaps the
compiler is generating instructions for the wrong chip version or

Maybe someone else is more familiar with this and can suggest what to try next.
