the extlinux as below:


the block device as below:

2.according to shutdown the power, filesystem are loading ok, but it cannot been loaded from reboot;the error log as below:
sd_card_reboot_error.txt (86.1 KB)

3.my custom carrier board Hardware schematic as below:


the dts only change it from “disabled” to “okay”

4.the 118 pin can not been configured as DC detect, so I configure the Set to low level by hardware.

This kind of issue has been replied for many times. Please search “sdmmc3” over this forum first.

You need to provide “vmmc-supply” and “cd-gpios” to your sdhci device tree node.

The problem has been solved,thanks!
