The problem of emulating external storage in am335xevm

I want to bring up the sources of JellyBean in am335xevm . The board has been downloaded from JellyBean.

I also want to connect / data / media / as external storage on my board. For this, I referred to this link.

I used the following codes in init.vendor.rc file

on init
    # for backwards compatibility
    mkdir /mnt/shell/emulated 0700 shell shell
    mkdir /storage/emulated 0555 root root

    export EXTERNAL_STORAGE /storage/emulated/legacy
    export EMULATED_STORAGE_SOURCE /mnt/shell/emulated
    export EMULATED_STORAGE_TARGET /storage/emulated

    symlink /storage/emulated/legacy /sdcard
    symlink /storage/emulated/legacy /mnt/sdcard
    symlink /storage/emulated/legacy /storage/sdcard0
    symlink /mnt/shell/emulated/0 /storage/emulated/legacy

on post-fs-data
    mkdir /data/media 0770 media_rw media_rw
    chown media_rw media_rw /data/media

on fs
    setprop ro.crypto.fuse_sdcard true

service sdcard /system/bin/sdcard /data/media /mnt/shell/emulated 1023 1023
    class main

and file storage_list.xml

<storage android:mountPoint="/storage/sdcard0"
             android:storageDescription="@string/storage_internal"
             android:primary="true"
             android:emulated="true"
             android:mtpReserve="100" />

I also print to /system/core/sdcard/sdcard.c.

When I see magazines for this, it often crashes. I also attached logcat.
