Keep in mind that Linux enumerates the busses in a different order than
the hardware does. If you are using the low speed header's I2C that's
likely I2C #6 under Linux.
https://github.com/MinnowBoard/minnow-max-extras/blob/master/calamari/calamari-i2c-eeprom.sh
Has an example to check what addresses are used on the bus (line 28).
That will likely help significantly.
