Hi,
My questions relates with a board that is using an imx8mp, but I guess the answer would be similar to other i.MX processors.
I have a board with a SOM. Many pins from the SOM connector are not connected to anything on the baseboard. From what I read here and here those pins must be configured as gpio input and pull-up.
I would like to know how to achieve that under Linux and/or U-Boot :
I was not able to find an example of pinctrl configuration for unused pins within Linux sources. So I guess it is more likely to be the first case ?
I also would like to know what pinmuxing mistakes could lead to damage the SoC and therefore what should I be really careful with ?
Thanks a lot,
