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

The pinmux command is only available if CONFIG_CMD_PINMUX=y.
The return value $? is set to 0 (true) if the command succeded and to 1 (false) otherwise.
