Theres a thread a few posts down, looking at the same issue clocked from yarns
I'm guessing you're clocking from analogue clock in?
If it all works fine when you use internal clock, the good (and bad) news is your bsp is probably fine its 'just' the firmware has a pretty bad bug..
If it's still not outputting gates when you use internal clock, its possible the unit is faulty. (don't take this as gospel btw just my best guess)
