Hi

I’m trying used the UART on BeagleBone Black, but in my “/dev” only find the ttyO0, and I need to use the ttyO1, how I do to enable this device in the “/dev”? Someone can help me?

Thanks

André,

Open the file uEnv.txt with nano:

sudo nano -w /boot/uboot/uEnv.txt

and add at the end of optargs= the following:

capemgr.enable_partno=BB-UART1

Then just save and exit (CTRL-X) and reboot.
