Ok Robert, If I enable the 8250/16550 in the menuconfig this driver connects to /dev/ttySx. The ttyO[1,2,4] appears and vanishes with the BB-UARTx dtbo's The ttySx devices does not work anyhow (while not enabled via any dtbo) Is there any method of enabling the ttySx devices if a 8250 driver is preferred? Or, a method to associate the 8250 driver with the ttyOx devices? Regards Terje
