    Thanks Iam currently looking into it idkAM572x_pinmux.c

    is there any specific document for changing the pinmux and rebuilding the MLO

    because I believe MLO does every pinmux initialization,clock initialization,DDR initialization and then it transfer the control to application which is the app file

    and als i believe the app cannot do any pinmux changes
