I have the BeagleBone Black A5A using the latest image from Angstrom. In my uEnv.txt I have the following: optargs=quite ddm.debug=7 capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN capemgr.enable_partno=BB-UART1,BB-UART2,BB-UART3,BB-UART4,BB-UART5
In my code, I open the UARTs as follows: handle=open(info.device.c_str(),O_WRONLY|O_NONBLOCK|O_NOCTTY); I then try to open the following: /dev/ttyO0 /dev/ttyO1 /dev/ttyO2 /dev/ttyO3 /dev/ttyO4 /dev/ttyO5 I get an error opening /dev/ttyO3. I know it doesn't have a RX, but I only want to send data. Is there something else I need to do to enable the UART for writing? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
