SDcard mount problem with vold

[sreedhar b]

Hi All,

 

I am seeing similar problem as is highlighted in the below link in my environment,

http://groups.google.com/group/android-developers/msg/9e4c3176ef685f9e

 

1. Manual mounting of sdcard 

 

If i run the below command  manually after the android boots up,

$mount -t vfat /dev/block/mmcblk0 /sdcard

 

Then only the sdcard is getting mounted and as mentioned in the above link,

I also see Gallery and Camera do not recognize the SD card even it's mounted this way.

 

2. No manual mounting of sdcard 

 

While not doing this manually which is what ideally expected, i  got the following errors and the sdcard is not mounted 

 

The log gives  some error like this
E/vold    (  620): Unable to open '/sys/class/switch' (No such file or directory)
E/vold    (  620): Cannot start volume '/sdcard' (volume is not bound)

 

Please let me know how to overcome this issue. I faced the same issue with Cupcake and also with Donut 1.6 r1 now.

 

Regards,

Sreedhar

Sorry the mmc partition in my system is different.

 

The correct command i am using :

mount -t vfat /dev/block/mmcblk1p1 /sdcard ,

 

earlier i wrongly said as

mount -t vfat /dev/block/mmcblk0 /sdcard

Hi,

Did you modified your vold.conf?

Hi,

 

This is the modified vold.conf which i am using ,

 

## vold configuration file for the emulator/SDK

volume_sdcard {
    ## This is the direct uevent device path to the SD slot on the device
    media_path     /devices/MMC/mmc_host/mmc1

    media_type     mmc
    mount_point    /sdcard
    ums_path       /devices/platform/usb_mass_storage/lun0
}

 

Regards,

Sreedhar

Yes i tried this.

 

Even after doing this i am getting these errors:

 

E/vold    (  620): Unable to open '/sys/class/switch' (No such file or directory)

E/vold    (  620): Cannot start volume '/sdcard' (volume is not bound) 

 

E/vold    (  620): Unable to open '/sys/class/switch' (No such file or directory), this error i am able to overcome by enabling the switch class in kernel.

 

But i am still stuck at this second error,

E/vold    (  620): Cannot start volume '/sdcard' (volume is not bound) 

 

But just to inform if i try manually the below command, the mount happens

$mount -t vfat /dev/block/mmcblk1p1 /sdcard

 

 

 

Regards,

Sreedhar

hi,

Is the media_path in vold.conf right?
I am not sure about your platform, maybe it should be /devices/
platform/xxx...
try below on target board and find the path.
# ls /sys/devices/platform

Hi,

 

#ls /sys/devices/platform

 

it shows uevent and some other components specific to my platform and no MMC components.

 

But i have something like this,

 

# ls /sys/devices/MMC
driver     irq0       power      subsystem
id         mmc_host   resource   uevent

# ls /sys/devices/MMC/mmc_host
mmc1

# ls /sys/devices/MMC/mmc_host/mmc1
device     mmc1:bf0a  power      subsystem  uevent

 

Could you please let me know in that what should be my vold.conf ?
