SD card not accessible(checked via Gallery app)

Observed in https://android-build.linaro.org/builds/~linaro-android/panda/#build=407 as well.

The same problem was fixed on vexpress by using this patch: http://android.git.linaro.org/gitweb?p=platform/system/vold.git;a=commit;h=21d39989c4b9aa5707a779265a2783aa6c2e5677

I don't know how to go about getting that into ICS, there doesn't appear to be a linaro_andoid_4.0.1 branch in vold.

I have committed the patch to vold which increase the maximum number of partitions to 8, see
http://android.git.linaro.org/gitweb?p=platform/system/vold.git;a=commit;h=580eb3e00cd1209a5cb75a8e67d28808a25b20a1

On the Versatile Express board I have a /etc/vold.fstab file, which mounts the sdcard partition and this now works correctly. Other devices may not have this (snowball doesn't), so this bug is probably not fixed on those boards.

I notice that the ti/panda device doesn't use a vold.fstab, instead it seems to create a virtual sdcard in /data/media (see init.omap4pandaboard.rc). I don't know if this is the new preferred way of emulating sdcard in ICS?

Fixed on vexpress, see https://bugs.launchpad.net/linaro-landing-team-arm/+bug/897176/comments/4

Seen on ICS in build, https://android-build.linaro.org/builds/~linaro-android/staging-panda-11.12-release/#build=2.

Valid for https://android-build.linaro.org/builds/~linaro-android/staging-imx53-11.12-release/#build=2 as well.

Still valid for https://android-build.linaro.org/builds/~linaro-android/staging-snowball-11.12-release/#build=4

For iMX53 11.12 final RC: https://android-build.linaro.org/builds/~linaro-android/staging-imx53-11.12-release/#build=7

I can enter the "/sdcard" directory, and even can create a file there. But I can't test this because there is totally no display out. My monitor always shows "no signal" after I connected it to the iMX53 board with the VGA cable.

Use busybox vi test.txt to ceate a file named test.txt:

root@android:/sdcard # pwd
/sdcard
root@android:/sdcard # ls -l
-rw-rw-rw- root log 1 1970-01-04 11:34 test.txt
root@android:/sdcard #

Just creating a file might succeed even if the card isn't mounted, you
would just be writing a file to the directory where the mount should be.

A better test to see if sdcard is mounted is with the "df" command and
see if a filesystem on /mnt/sdcard is listed.

I just fixed this in landing-snowball for both 4.0.1 and 4.0.3.

Gerrit change-Id: I6c15cebb983ee8b9261d07f9444101a96e2d9dcd

Also observed on staging-imx53 release:

Also observed in https://android-build.linaro.org/builds/~linaro-android/landing-snowball-12.01-release/#build=5

/mnt/sdcard is accessible from console and has a number of subdirectories e.g. Music.. But even when populating these directories with .jpg- and .mp3 files, they are not discovered by neither Gallery nor Music app.

Observed on the 12.01 RC build:

Bug still present in https://android-build.linaro.org/builds/~linaro-android/snowball-ics-gcc46-igloo-stable-blob-12.02-release/#build=1

Observed on:

https://android-build.linaro.org/builds/~linaro-android/imx53-ics-gcc46-freescalelt-stable-open-12.02-release/#build=1

Also happens on imx6 12.02

Moving to 12.03.

Start fixing the bug on 29-Feb-2012.

The bug is fixed at Mar-9-2012.

Please check this gerrit link:

http://review.android.git.linaro.org/1568

Or the patch in the attachment.

Issue:
The picture review is not stable in gallery. As there is some features of libEGL has not been implemented yet.

E/libEGL ( 2346): called unimplemented OpenGL ES API

Further:
This patch also solves the bug of the SD usage information missing issue in "Setting->Storage".

This bug report is misleading. Also the associated test case "sd-mmc". The original report was about the partition not being mounted or visible and the Gallery app just a way to check that.

Now when the partition is visible and files can be found by "ls" in the console - it turns out that (in at least one case) the Gallery app can't show anything anyway.

Observed on https://android-build.linaro.org/builds/~linaro-android/panda-ics-gcc44-kwg-upstream-open-12.03-release/#build=3

Files are there and seen by Linux:
root@android:/mnt/sdcard/Pictures # ll
----rwxr-x system sdcard_rw 3337988 2012-01-08 10:03 20120108-110319.jpg

But no pictures show up in Gallery.

This bug report should NOT be used when Gallery fails.

I will open a separate bug just for Gallery and relate a failed test case "gallery-app" for that bug.

Observed on:

https://android-build.linaro.org/builds/~linaro-android/imx53-ics-gcc46-freescalelt-stable-open-12.03-release/#build=5

After clicked the "Gallery", I got "No external storage available". And there is nothing under the path "/mnt/sdcard":

root@android:/mnt/sdcard # pwd
/mnt/sdcard
root@android:/mnt/sdcard # ls -la
root@android:/mnt/sdcard #

Fixed on iMX6 12.03

For iMX53, observed on:

https://android-build.linaro.org/builds/~linaro-android/imx53-ics-gcc46-freescalelt-stable-open-12.04-release/#build=3

After ran "df" in serial console, I got:

root@android:/ # df
Filesystem Size Used Free Blksize
/dev 468M 44K 468M 4096
/mnt/asec 468M 0K 468M 4096

/cache 247M 6M 241M 1024
/data 495M 50M 445M 1024

After launched "Gallery" app, I got a pop up window:

No Storage!
No external storage available.

Bero,

Noticed that you fixed this issue on i.MX6. Can you also do the same fix on i.MX53 Android?

For landing team's concern, in kernel level, SD card is supported well in i.MX53, and I can manually mount SD card partitions well. Like: # mount /dev/mmcblk0p2 <mnt.point>

Thanks.

According to the test case:

https://wiki.linaro.org/Platform/QA/TestCases/Android#sd-mmc

No SD card partition mounted:

root@android:/ # df
Filesystem Size Used Free Blksize
/dev 468M 44K 468M 4096
/mnt/asec 468M 0K 468M 4096

/cache 247M 6M 241M 1024
/data 495M 50M 445M 1024

This actually works fine on https://android-build.linaro.org/builds/~linaro-android/imx53-ics-gcc47-freescalelt-stable-open-12.05-release/#build=2. I suspect that the previous results were due to not putting an SD card into the SD.MMC slot. I verified that I could open images on /dev/sdcard.

Updated https://wiki.linaro.org/Platform/QA/TestCases/Android with new instructions for iMX53.

Yes, the SD card can be mounted there after inserted it to the MMC slot. However, the Gallery still can't recognize the pictures and audios I put on it. Do I miss anything?

For iMX53, on build:

https://android-build.linaro.org/builds/~linaro-android/imx53-ics-gcc47-freescalelt-stable-open-12.05-release/#build=3

The picture on SD card can be finally recognized, however, the video files still can't be discovered.
