RPi4 have no access to sdcard #55

Closed matviizorin closed 4 years ago

matviizorin commented 4 years ago

After changing the directory to /sdcard other adb shell command we can see the log below:

sdcard ``` rpi4:/ $ cd sdcard /system/bin/sh: cd: /sdcard: No such file or directory ```

sdcard refers to /mnt/user/0 path (/sdcard -> /storage/self/primary -> /mnt/user/0/primary) but containing folder is empty:

folder content ``` rpi4:/ # ls -la /mnt/user/0 total 0 drwxr-x--x 2 root root 40 1970-01-01 00:00 . drwxr-xr-x 3 root root 60 1970-01-01 00:00 .. ```

Also, creating a file on the target device fails with the folowing list of errors in adb logcat:

v0.3.0 uses kernel v5.7 for broadcom platform. Starting from kernel v5.7 sdcardfs is not provided by Google, but required for Android up to v10

Best solution for now is to move to v5.4 stable. Both Google [1] and Broadcom [2] supports it.

Thanks, I'm going to change the kernel version in the nearest time

This commits have to be reverted for enabling sdcardfs starting from v5.7. I've successfully done it for PP on kernel v5.8

I've got an issue with composition committing after migrating to v5.8 with android-mainline-tracking patches.

logcat ``` 08-07 07:24:25.591 197 197 E hwc-drm-display-compositor: Commit test failed for display 0, FIXME 08-07 07:24:25.591 197 197 E hwc-drm-two: Failed to apply the frame composition ret=-13 08-07 07:24:25.591 205 205 E HWComposer: presentAndGetReleaseFences: present failed for display 0: BadParameter (4) ```

Trying to investigate and fix this issue.

I've cherry-picked the commit for DRM driver to support Android (https://github.com/GloDroid/glodroid_forks/commit/2fe6160b72530189a0f965eee5435adf86cf350a) and as for now, the composition creation works properly. WIP branch is pushed to the fork as a result (kernel-broadcom-next).
