i2c-lpi2c

Driver for inter-integrated circuits on the Toradex Apalis i.MX 8 QuadMax Ixora Board

Syntax:

i2c-lpi2c [board_specific_option [board_specific_option]...]
         [generic_option [generic_option]...]]

Runs on:

QNX OS

Options:

There are Apalis i.MX 8QM Ixora-specific (single-dash) and generic (double-dash) options available.
CAUTION:
The Apalis i.MX 8QM Ixora-specific options must always appear before generic options, otherwise the driver fails to initialize. For example, the correct sequence would as follows: 
i2c-lpi2c -v --u0
However, if you incorrectly issue the command in the wrong sequence as shown here, it will fail:
i2c-lpi2c --u0 -v

Apalis i.MX 8QM Ixora-specific options:

These are the board-specific options available for this driver.

-b
