Synopsis
|
|
--------
|
|

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
|
|
|
|
