I have a task to change modes of some pin's to alterbatives. What I have learned so far is that every ball has a number of modes, which can be changed. Found the current layout at SPF-28616_C.pdf file, so I reworked it to imx6ul_pinout.xlsx where in yellow I pointed the modes I want to set for the pins. As far as I understand, pin modes should be changed in files imx6ul-14x14-evk.dts and imx6ul.dtsi, am I right? Can someone show me what changes are needed to change modes from default to the ones I want?
One more question. I've been told that at the real device to F16 pin instead of evk's ENET1_RXD0 will come completely different signal, not present at the table. Do I have to change anything to be able to read it or I can leave things as is?
