OK, I made those changes as well, and the software trigger now works!
OK, so what about an external trigger source? If I understand what's
going on, then I should undo the changes we've just made, make EXSYNC
free running, run ./test_itifg with the -t option and connect my
trigger source to the board - and it should work...?

Well, this is what I've tried, and I'm afraid it doesn't work. The
trigger source is definitely working - I've got a TTL level trigger
connected to the board.
