i2c-lpi2c

I2C manager for Lower Power I2C interface

Syntax:

i2c-lpi2c [options]

Runs on:

QNX OS

Options:

There are i.MX 93 EVK board-specific (single-dash) and generic (double-dash) options available.
CAUTION:
The i.MX 93 EVK board-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

i.MX 93 EVK board-specific options:

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