…I am not asking you to just type whatever I write here.
If your power supply is called en_sd_card regulator, then give vmmc-supply to en_sd_card.
And also stop sharing partial log. Please only share full dmesg from now on.

en_sd_card gpio correspond to design on SDCARD_CD_L.

Thanks！
I try a test,i find tegra186-p3636-0001-a00-power-tree.dtsi.
platform/t18x/lanai/kernel-dts/common/tegra186-p3636-0001-a00-power-tree.dtsi flow as：

so I try vmmc-supply = <&spmic_sd2>,but sd card donot work.

HI,
Do you write the en_sd_card for the VDD_3V3_SYS on your schematic? That what vmmc-supply is doing.
On my schematic the VDD_3V3_SYS is highed（3.3V）default.
en_sd_card only enable power supply chip，but en_sd_card donot power-supply sd card(/sd card chip).
My company of product is xavier nx，sd crad is ok(sd card hardw is same)，but sd card
dts flow as：
sdhci@3440000 {
cd-gpios = <&tegra_main_gpio TEGRA194_MAIN_GPIO(Y, 4) 0>;
nvidia,cd-wakeup-capable;
vmmc-supply = <&p3668_vdd_sdmmc1_sw>;
vqmmc-supply = <&p3668_spmic_sd3>; **//default,if vqmmc-supply delete，the sd card still do work.**
status = "okay";
};

Can it be analyzed by log， Thanks！
Can you just give us the error log without any debug print added by you?
CRC error is probably from the hardware.
Hardware do work，I try to xavier nx platform + this sd card party also do work，I think that CRC is probably from software config.
Hi @shaorui,
What is the device tree you are using on the NX platform? What is the vmmc-supply you gave on NX case? Also a 3.3V always-on regulator?
code is TX2 NX.My kernel R32.5.1.
I try a test, confirm hardware do work.
I know the issue is on TX2 NX. I just want to know how did you configure NX before? This part should be similar.
Yes.
My question is sd card on TX2 NX.
CRC error is the reason？project time is urgent，Thanks
I already sent you a private message. Please check.
