Building panther x2 openwrt image, reboot will lost all configurations

I built an OpenWrt image for the Panther X2 and flashed it onto the TF card. However, upon rebooting, I found that all configurations were lost. Upon searching through the dmesg info, I came across the following content, which appears to indicate a TF driver problem.

[    6.971299] F2FS-fs (loop0): Mounted with checkpoint version = 31df0ab2
[    6.975151] mount_root: switching to f2fs overlay
[    6.979545] overlayfs: "xino" feature enabled using 32 upper inode bits.
[    6.979669] overlayfs: failed to verify origin (/, ino=29718, err=-116)
[    6.979684] overlayfs: failed to verify upper root origin
[    6.980129] mount_root: mount failed: Stale file handle, options lowerdir=/,upperdir=/overlay/upper,workdir=/overlay/work
[    6.980324] mount_root: switching to f2fs failed - fallback to ramoverlay

after add kmod-mmc package

Kernel modules --> Other modules --> kmod-mmc

the problem fixed!

dmesg information become these.
