Hello, I have updated my machine to the newest image and kernel that BBB.io/latest-images provide. Also, I use config-pin now. For example: sudo config-pin P9.17 i2c and then try sudo config-pin P9.18 i2c, too. That should open up your i2c address on your BBB or other bbb.io related boards.
Seth P.S. DTOs are old news as far as I am concerned. They have U-Boot Overlays now. Anyway, here is some reading on the subject: https://elinux.org/Beagleboard:BeagleBoneBlack_Debian#U-Boot_Overlays.
