The v3.8.x tree is still /dev/ttyOx ;) I was going to phase it in on mainline, but then ti made the switch on their v3.14.x-ti tree... So we bit the bullet. For systemd users, systemd fixed it up on boot.. For udev users, we now having working /dev/ttySx -> /dev/ttyOx rule... For everything else... We i didn't test.. ;) If it's any consolation, i did yell at the developers on linux-omap, how "fxxxd" up this was, specially since i was here during the ttyS -> ttyO mess. But i think we are now ready in 26-ish+ kernel releases to move back to ttyO... ;) Regards, -- Robert Nelson https://rcn-ee.com/ -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
