i2c-imx

Driver for inter-integrated circuits on the Honeycomb LX2 Workstation.

Syntax:

i2c-imx [board_specific_option [board_specific_option]...]
         [generic_option [generic_option]...]]

Runs on:

QNX OS

Options:

There are Honeycomb LX2-specific (single-dash) and generic (double-dash) options available.
CAUTION:
The Honeycomb LX2-specific options must always appear before generic options, otherwise the driver fails to initialize. For example, the correct sequence would as follows: 
i2c-imx -v --u0
However, if you incorrectly issue the command in the wrong sequence as shown here, it will fail:
i2c-imx --u0 -v
