pinmux command

Synopsis

pinmux list
pinmux dev [pincontroller-name]
pinmux status [-a | pin-name]

Description

The pinmux command is used to show the pin-controller muxing.

The ‘pinmux list’ command diplays the available pin-controller.

The ‘pinmux dev’ command selects the pin-controller for next commands.

pincontroller-name

name of the pin-controller to select

The ‘pinmux status’ command displays the pin muxing information.

-a

display pin muxing of all pin-controllers.

pin-name

name of the pin to display
