I suspect that you're not using the latest code in the trunk. Please
update, build and install that.  That will fix the segfault.

The fact that you're still getting the "Unable to retrieve
daughterboard info" message makes me think that you didn't
successfully update the firmware on the SD Card with the latest
firmware binary.
