Hi,
Just a personal suggestion. Can you stop putting your comment inside the grey box…?
This is really not very good to read when you put code and your comments in the same grey box together.
You can use that to put the code or log, but please do not put the comment in it…
Also, pin G,2 does not have module pin out on jetson NX at all… thus I am not sure why you put it in your regulator…
What is the dmesg result after you remove it? The gpio here needs to match the hardware design… if it does not exist on your design, then you don’t have to write it.
Your log still shows no sdmmc3 activity so far.
And, there are also lots of sdmmc3 case on this forum… you can refer to their dts too.
