Hello TM4C Forum,
The TI Pin Mux Tool now supports TM4C12x devices (limited launch for TM4C129XNCXAD, TM4C1294NCPDT, TM4C123GH6PM and TM4C123GH6ZXR) and can be accessed using the following link
Please do note that support for remaining devices will be made available in the next month release. This is an early release of the tool to asses any major issues with TM4C12x Pin Mux Code Generation before the full version is launched. We would be glad to accept any feedback/issues/enhancements with the tool launch. Also with the full release version of the tool planned next month the TM4C Pin Mux tool will be deprecated and completely replaced by the new tool.
Do note that a Desktop version is also being planned along with the enhancement to have the familiar Port Pin Nomenclature in the GUI for both Cloud and Desktop version
Regards
Amit
