The BBB manual says both these things about applying inputs to the I/O pins:-
NO PINS ARE TO BE DRIVEN UNTIL AFTER THE SYS_RESET LINE GOES HIGH. Do not drive any external signals into the I/O pins until after the VDD_3V3B rail is up. So, do these actually mean basically the same thing, or if not, which one is actually correct? Using the VDD_3V3B to gate external input is much easier because of its greater current capability but both are available on the headers so one could use either. (Or even worse, is it *really* an AND requirement?) When the BBB is powered down will these two signals go low early enough so that input signals gated by them will be removed in time? -- Chris Green ยท -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
