Hi All,
I am facing a issue when i try to mount a external sdcard in a custom
device which is running on Kitkat 4.4.2.
Below is the error which i am getting whenever sdcard mount happens.
03-11 23:25:32.229: E/cutils(553): Failed to mkdir(/mnt/shell/emulated/0):
Read-only file system
03-11 23:25:32.229: E/dalvikvm(553): cannot mountExternalStorage():
Read-only file system
My init.device.rc is as follows:
# no emmc file systems mounted at this point (system, data, pds, etc.)
# runs after "on early-init" and before "on early-fs"
# runs in charge-only-mode
on init
export PATH /system/sbin:/system/bin:/system/xbin:/sbin:/vendor/bin
write /sys/class/graphics/fbcon/cursor_blink 0
mkdir /mnt/shell 0777 shell shell
mkdir /mnt/shell/emulated 0700 shell shell
#mkdir /storage 0550 system sdcard_r
mkdir /storage/emulated 0555 root root
mkdir /mnt/media_rw 0777 media_rw media_rw
mkdir /mnt/media_rw/sdcard1 0700 media_rw media_rw
mkdir /storage/sdcard1 0775 root root
export EXTERNAL_STORAGE /storage/emulated/legacy
export SECONDARY_STORAGE /storage/sdcard1
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 /mnt/shell/emulated/0 /storage/emulated/legacy
#symlink /storage/sdcard1 /extSdCard
#symlink /storage/sdcard1 /mnt/extSdCard
fstab.device is as follows
# Android fstab file.
#<src> <mnt_point> <type> <mnt_flags and options> <fs_mgr_flags>
# The filesystem that contains the filesystem checker binary (typically
/system) cannot

MF_CHECK
/dev/block/system /system ext4 ro,noatime wait
/dev/block/cache /cache ext4
nosuid,nodev,noatime,nodelalloc,barrier=1,data=ordered wait,check
#/dev/block/panic /panic raw defaults wait

/devices/pci0000:00/0000:00:04.0/mmc_host/mmc1 auto vfat defaults
voldmanaged=sdcard1:auto
Whether i comment or uncomment the creation of symlinks to "/sdcard",
"/mnt/sdcard/", the behavior is the same.
When i explicitly mount sdcard from shell prompt using "mount" commnd, it
is able to mount.
Please help me to resolve this issue.
Thanks in Advance,
Anand.
