[MinnowBoard] Problem to exchange data on I2C

[Soussi, El-Houari]

Hi everybody,
I installed the version 14.04 of Ubuntu, updated  the kernel to 3.14.19, I checked the I2C is well activated in the BIOS and  I installed the module i2c-dev but I cannot still see any exchange through I2C #5.
I read in a discussion thread that board files are needed to have SPI & I2C devices work. Is it true? Where can I find these files? Otherwise, does somebody have an  idea?
Thank you,
El-Houari
