How to deal with unused pins in the imx8mm design

[31960865]

Dear community,

I'm using imx8m mini for a design.The "JTAG" "NAND" "SAI" "SDHC" group is not used in my products.So,How should i handle these pins? Can I just connect all input pins to ground  and leave the output pin directly floating? The hardware manual only introduces how to deal with some pins when not in use,other pins are only defined, can I deal with unused pins according to convention?

About the pins you do not using, how to deal with them you can see the https://www.nxp.com/webapp/Download?colCode=IMX8MMHDG. You also need to refer to the datasheet. For the JTAG maybe you need use for debug M4 core.
