18.2 Default Configuration of GPIO
By default the GPIO interface is not enabled. It is necessary to reconfigure the
GPIO pins as identified in section 18.1 through use of the commands and actions
described in section 18.3.
18.3 Configuring GPIO ports
The available GPIO can be configured as inputs or outputs using a set of CLI
commands. The commands listed in Table 39 provide control of the GPIO and
should be configured to match the application.
Table 39 - GPIO Default Settings Command List
Command Description
io-dir
Sets the direction of the indicated port. This command sets
the direction without requiring a restart or power cycle.
This command is temporary and is not persistent across a
restart or power cycle. To set the default direction of the
ports the io-dir-f or io-dir-g commands must be
used.
The command has the same bit restrictions the io-dir-f
and io-dir-g command have.
The is a combination of the port name (g or f)
and the bit to apply the state to (0 through 7), for instance
g0
would affect the first pin on port g.
The can be set as either in or out depending
upon the desired direction for the GPIO.
