I started working with the Exadler DMCC and a Beaglebone Black for a motor
control application and it is working OK. I bought some BBG's as they are
neater for what I am doing (we don't need a power connector or HDMI) but
the I2C won't work. There are actually 2 I2C boards added to the BBB. I2C
detects them on the BBB but not the BBG.
The results for i2cdetect are below. I have tried mutliple BBG's with the
same result.

Does any one have any suggestions for the cause?
