Can't synchronize files from Windows to f_mass_storage

[csoapy]

Our bsp version is based on 4.14.98_2.0.1, I also tried 4.14.98_2.1.0, but still failed to synchronize files: ls command can't shows files created from Windows before rebooting board. Maybe remount should works, but shoundn't be synchronized once the file was created from Windows? I also tried refresh folder on Windows and sync from our board, but nothing happened.

Here are my settings. Is there something I missed?

    local img=/run/camel/fat.img

    local mpoint=/run/camel/udisk

    mkdir -p $mpoint

    echo "mount_udisk($1, $2) to $mpoint"

    dd if=/dev/zero of=$img bs=$2 count=1

    mkfs.vfat $img

    mount $img $mpoint

    mkdir -p /sys/kernel/config/usb_gadget/$1

    cd /sys/kernel/config/usb_gadget/$1
