I'm desperately trying to do useful debugging of the samb11 - Atmel's refusal to provide a decent datasheet or code for their firmware is getting in the way. One of the things I've noticed is that when I can get the debugger to work at all, I often find that I'm looping at 0x54a:
0000054A b #-4
...which makes me think this is some kind of "we're screwed, so loop here" error handler. Anyone know what I might be doing that I wind up there so frequently? This generally happens after I call ble_event_task(20).
