SD card error on custom carrier board

Autonomous Machines Jetson & Embedded Systems Jetson Nano
1

SDK version 32.5

No cd pin, alway power on.

Even no clock output after enable sdmmc3 in dts.

Kernel detected sdcard when add “vqmmc-supply = <&max77620_ldo6>” to dts . But boot fail then.

The console log is:

The kernel patch mentioned in the post already done in version 32.5. https://forums.developer.nvidia.com/t/jetson-nano-sd-card-can-use-but-kernel-prompt-error/154587

Our dts file list below

Thank you!

  1. No cd pins means you cannot hotplug it. Then you should not remove non-removable;

  2. You still need to assign a fake always-on regulator for your vmmc-supply.

Thank you for reply!!

Update dts, but still same error

Dts:

sdhci@700b0400 {/*SDMMC3 */

please give it a regulator that has regulator-always-on property.

Hi, WayneWWW,

The issue still there.
DTS is:

sdhci@700b0400 {/*SDMMC3 */
keep-power-in-suspend;
non-removable;
vmmc-supply = <&max77620_sd2>;
vqmmc-supply = <&max77620_ldo6>;
nvidia,vmmc-always-on;
mmc-ddr-1_8v;
mmc-ocr-mask = <3>;
uhs-mask = <0x0>;
sd-uhs-sdr104;
sd-uhs-sdr50;
sd-uhs-sdr25;
sd-uhs-sdr12;
max-clk-limit = <400000>;
tap-delay = <3>;
status = “okay”;
};

Please also upgrad to new jetpack release. 32.5 seems old.

For Nano, supported max release is 32.7.3.
And I read the release note between 32.5 and 32.7.3, there is no item related with sd card.

Would you please provide a dts sample of sdcard for Nano?
Thanks alot!

Hi,

Release notes do no cover such info. For example, max-clk-limit = 400000 jas beem removed for a long time.
