Why port is 0x0000?
setserial has not been updated in a long time and so does not understand newer port types. If you look at the man page for the 'uart' parameter, you'll see the known values are quite limited compared to the current known port types in <linux/serial_core.h> Nor does it understand memory-mapped port addresses. > Why any setserial command fail? > > root@beaglebone:~# setserial /dev/ttyO4 baud_base 115200 > Cannot set serial info: Invalid argument The omap_serial driver does not allow port information to be changed via setserial.

You can set the tty baud rate with stty, like so: $ stty -F /dev/ttyO4 115200 Regards, Peter Hurley -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
