is SD_A_VSEL input or output?

    Hello,


    in the domentation of PicoCore MX8MN the pin J2-54 is mentioned as input.



    Below in chapter 4.2 it is mentioned as output.




    What should I do with this pin? I guess it must be left unconnected.


    Thank you for reply.


    Best regards,

    Daniel

    Hello,


    Sorry for the mistakes in our documentation. We are going to correct them as soon as possible. Thank you for your kind feedback!


    SD_A_VSEL is actually an output pin to set the voltage level of SDIO_A Pins between 1.8V and 3.3V. If you don't need to select voltage level externally from the baseboard (e.g. with a switch) you can left this pin unconnected.



    I hope the answer was helpful for you!
