Beaglebone Black - Enabling ttyO1 / ttyO5 - [SOLVED]

[Gronk]

1. Mount the boot partition

mkdir boottemp
mount /dev/mmcblk1p1 boottemp

2. Append the following to the last entry uEnv.txt (now in boottemp)

capemgr.enable_partno=BB-UART1,BB-UART2,BB-UART4,BB-UART5

3. Reboot

I found the solution here for Angstrom, but it works fine for Arch Arm
