First check that you are using the correct usart node, don't remember in 2.6.39, either ttyS2 or ttyO2 2nd, enable earlyprink.. Otherwise, good luck on 2.6.39! ;) 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.
