i.MX6UL can handle external pins in many different ways and most of them can be configured as GPIOs. When a pin is set as a GPIO, it is possible
to read its value, change its direction or change output value directly from the shell.
{{ImportantMessage|text=There aren't GIO already configured in the [[AXEL_ULite_SOM/AXEL_ULite_Evaluation_Kit | AXEL ULite EVK]].<br>Here below an example of GPIOs usage in the i.MX6UL standard product [[SBC_Lynx_SBC | SBCLynx]]}}
