Loading I2C driver
Dedicated pins for I2C are configured for GPIO, these pins can be configured as I2C bus while change the pin configuration. In order to change the configuration, you must load the driver.
$ modprobe aml_i2c
If you have to load the driver every time whenever your ODROID-C1 starts, simply you can register the driver into /etc/modules.
$ sudo echo "aml_i2c" >> /etc/modules
This adds one line at end of the file, /etc/modules, and load the driver on boot automatically.
