"/mnt/media_rw/sdcard0" is in output but no "/storage/sdcard0".

Hi Vishal,
For the SD MMC test on Samsung Arndale board, the value of EXTERNAL_STORAGE doesn't match with the output of "df":
root@arndale:/ # df Filesystem Size Used Free Blksize /dev 1000.6M 164.0K 1000.4M 4096 /mnt/asec 1000.6M 0.0K 1000.6M 4096 /mnt/obb 1000.6M 0.0K 1000.6M 4096 /system 739.9M 371.1M 368.8M 4096 /cache 243.9M 2.0M 241.9M 1024 /data 487.8M 51.4M 436.4M 1024 /mnt/media_rw/sdcard0 5.8G 12.0K 5.8G 4096 /mnt/secure/asec 5.8G 12.0K 5.8G 4096
root@arndale:/ # echo $EXTERNAL_STORAGE /storage/sdcard0 root@arndale:/ #
"/storage/sdcard0" is not in the output of "df". According to the output, the storage actually locates at "/mnt/media_rw/sdcard0", and I couldn't see there is any symbol link between them:
root@arndale:/ # busybox ls -ld /mnt/media_rw/sdcard0 drwxrwx--- 4 media_rw media_rw 4096 Jan 1 00:01 /mnt/media_rw/sdcard0
root@arndale:/ # busybox ls -ld /storage/sdcard0 drwx------ 2 root root 0 Jan 1 00:00 /storage/sdcard0 root@arndale:/ #
However, data can be successfully written to /storage/sdcard0:
root@arndale:/ # written_message="abcdefghijklmn" root@arndale:/ # echo $written_message > $EXTERNAL_STORAGE/sd-mmc-test.txt root@arndale:/ # echo $? 0 root@arndale:/ # cat $EXTERNAL_STORAGE/sd-mmc-test.txt abcdefghijklmn root@arndale:/ # cd /storage/sdcard0 root@arndale:/storage/sdcard0 # ls sd-mmc-test.txt root@arndale:/storage/sdcard0 #
But file "sd-mmc-test.txt" doesn't exist under "/mnt/media_rw/sdcard0"
root@arndale:/storage/sdcard0 # cd /mnt/media_rw/sdcard0 root@arndale:/mnt/media_rw/sdcard0 # ls LOST.DIR root@arndale:/mnt/media_rw/sdcard0 #
Something wrong in the output of these storage partitions? The build I'm using is #386:
