Dear Community,
My kernel (R32.5.1) works ok ,but sd card doesn’t work on my board.
Some similar problems were found from forums, but none of them can solve the problem of not being able to catch SDCard.How can we use the SDcard?Thanks !
$ cat /proc/device-tree/sdhci@3400000/status
okay

Moving this topic from the Community Feedback forum to the TX2 forum.
I am not sure what kind of topics did you check. This one comes out in my first search result.
sdhci@3400000 is also not sdmmc3.
I am trying to modify this，but sd don’t work，
sdhci@3440000 {
status = “okay”;
//cd-gpios = <&tegra_main_gpio TEGRA_MAIN_GPIO(X, 4) GPIO_ACTIVE_HIGH>;
cd-gpios = <&tegra_main_gpio TEGRA_MAIN_GPIO(C, 3) 0>;
nvidia,cd-wakeup-capable;
/delete-property/ non-removable;
vmmc-always-on;
nvidia,sd-device;
};
kernel log as follows:

Where is your vmmc-supply? and mmc-ocr-mask = <3>;?

Please share the full dmesg, the full dts and the schematic of your board design on the sdcard part.

Please attach the full dts. Not just copy and paste a partial one.
Please provide the mail，thanks
We don’t provide any mail here. What do you need to provide through mail?
You already provided the schematic and dmesg , the remaining one is the full dts and that is not a private information.
Other people also just directly attach their dts here.
Hi,
If you have a “en_sd_card” for the card power source, then you should give it to your vmmc-supply.
Also, the method to dump full dts is to use the dtc tool to convert the dtb file back to dts.
This is not what we want. We already knew the patch. What is the difficulty to understand this comment?

How to use dtc tool？I can not use this tool，Thanks.
