Mt7621 MicroSD card not identified

For Developers

I use OpenWRT 22.03.4, CPU is mt7621 and dts declare sdhci:

&xhci {
        status = "okay";
};

&sdhci {
        status = "okay";
};

After compiling openwrt, burn it to the board. inserted SD card, I run dmesg and ls -l /sys/block no message output.

I sew the mmc_block and mmc_core kernel module is loaded.

# dmesg | fgrep mmc

# ls -l /sys/block | fgrep mmc

# lsmod | fgrep mmc
mmc_block              29974  0
mmc_core              100928  2 mmc_block,sdhci

The SD card is fine, but the SD inserted into the board OpenWRT won't recognize it.

Is missing linux modules?

Solved after install kmod-sdhci-mt7620
