Infinite Loop: A situation where in searching for the answer to something your own blog is on the first page of Google results, which results in you reading your own posts, and then searching again… and so on.. and so on…

So to break the cycle I’m posting this here:

Enabling the third (but second external) I2C bus on the Beaglebone Black (and shouts out to the original poster, Fortune Datko):

That won’t quite work, though, at least on on mine.

The command line should be this (with a ‘9’, not an ‘8’):

echo BB-I2C1 > /sys/devices/bone_capemgr.9/slots

And for kicks, test it out:

i2cdetect -r -y 2

That is all.
