From embeddedTS Manuals
The i.MX6 supports standard I2C at 100khz, or using fast mode for 400khz operation. The CPU has 2 I2C buses used on the TS-7990.
I2C 0 is used for many onboard peripherals only, but I2C 1 is unused and brought out to the DIO header pins 1/3.

The kernel makes the I2C available at /dev/i2c-#. You can use the i2c-tools (i2cdetect, i2cget, i2cset), or you can write your own client.
