Please compare your full dts with this one.
If all the properties are same, then we should check the hardware design.

Hello,
Are you talking about this file?
Thank you.
Hello,
I’m using the diff function of the editor to compare.
It seems that there are other parts.
I don’t know when I see it.
Could you please confirm?

Thank you.
Just compare the sdmmc3 controller part…
Hello,
Everything seems to be the same except for the address value.
May I ask you to cross check the file I gave you?
I’m not sure
Thank you.
Sdmmc3 controller means the sdhci where you added the cd gpios and always-on property
Hello,
The left is the dts file I made, and the right is the dts file I told you to compare.
Something is different. And vmmc-always-on is not applied to the dts file you told me to compare.
Thank you.
Just add those missing on your side back. Except the phandle.
And don’t remove the always-on. It is needed.
Hello,
Thank you for your hard work.
everything you told me
tegra210-porg-p3448-common.dtsi
I have added it to sdhci@700b0400
Can I add it here as well?
Thank you.
Hello,
Is it possible to exclude all lines containing phandle as follows?
linux,phandle = <0xc4>;
phandle = <0xc4>;
phandle is just a id and it differs on each person’s device tree. Thus, no need to care about others’ phandle.
Please also share me the full dts.
non-removable;
This is not needed. Please remove it.
Can you also try a hotplug case and share log? Do not plug the sdcard during boot. Hotplug it after system boots up.
Hi,
Can you measure and check if there is 3.3v on the sdmmc power source when you insert the card?
Hello,
Where can I take pictures with an oscilloscope?
Thank you.
Hello,
It is exactly 3.3v.
Thank you.
