Some processor’s GPIO settings on the i.MX Pins Tool version 7 may not show allow to select direction and just show an option “Input/Output” as shown. This will be fixed, but the settings can be changed on the local processor data as a workaround.
For more information and documentation for the Pins Tool for i.MX please visit its home page on the link below:
First, find where the Pins Tool data package is stored. To do this open the Pins Tool and click Help > About. On the About screen click the Details button. Take also note of the name of the package that needs to be fixed.
Go to the location where the data package is stored and find the processor data. The file that would need to be updated is signal_configuration.xml
Find the GPIO pin data and change the directions from the string ““inOut”to the string “in out”. Then save this file.
Close and reopen the Pins Tool. The direction on the updated package should now show the options Input and Output.
