→Texas Instruments Pin Mux Utility
Software installation and generic usage documentation is available on [http://processors.wiki.ti.com/index.php/Pin_Mux_Utility_for_ARM_MPU_Processors this TI wiki page]
Pin Mux Utility also warn the user if there's a conflict in mux usage (e.g. the same pin configured for two function) and does not allow to export the source code when this kind of problems arise. Please take a look, for example, at [[Additional UART on Linux (Naon)]] article for a step-by-step guide in how to change pin mux configuration and how to fix conflicts.
