AFAIK the only way to provide wake events on am33xx would be to mux the RX pin temporarily to a GPIO input. And sounds like that may work only if the GPIO is in the first GPIO bank that's always on. I don't know if the other GPIO banks on am33xx can provide wake up events. > So I have nothing on HW around that could test wakeup scenario. Bummer :( I'll give it a try again for the next revision.
