"adb remount" fails with latest android tip code for hikey960

[MandipS]

Hi,

I have tried to flash latest android tip code on Hikey960, flashing seems fine, but after boot, “adb root” is fine, but “adb remount” fails with below error.

Waited one second for gsiservice (is service started? are binder threads started and available?)
Could not acquire IImageManager: Invalid path
Overlayfs setup for /system failed, skipping: No such file or directory
Could not acquire IImageManager: Invalid path
Overlayfs setup for /vendor failed, skipping: No such file or directory
Could not acquire IImageManager: Invalid path
Overlayfs setup for /system_ext failed, skipping: No such file or directory
Could not acquire IImageManager: Invalid path
Overlayfs setup for /product failed, skipping: No such file or directory
No partitions to remount
remount failed

I have used below command to build.
$ make TARGET_KERNEL_USE=5.4 HIKEY_USES_GKI=true -j32

I have used “device/linaro/hikey/installer/hikey960/flash-all.sh” to flash.
Also noticed that it uses super.img and not system.img and vendor.img. Can someone help me understand what exactly “super.img” is?

Thanks.

Thanks for the pointers regarding dynamic partitions.

Do you have any suggestion for “adb remount” fails with android tip code?

According to the logs, @jstultz is responsible for those changes, so he’d probably be best able to answer you on that.

However, my recommendation is this; you shouldn’t have to remount those partitions. If you need to change things on them, implement those changes in the build tree (i.e. /device/linaro/hikey/), run a build, and write the updated image.

Apologies. While we have had some recent fixups, I did miss one edge case with the hisi-bootloader.

A fix is here:

Let me know if you still have trouble after re-flashing with that fix.

Thanks @jstultz, with this change “adb remount” is working fine.

$ adb remount

Trying to flash the hikey960 from ubuntu platform with the latest fastboot tool.
Below are my flash commands:

fastboot reboot

Could you please help me with this.

ignore.

cp /platform-tools/mke2fs /usr/local/bin/mke2fs /usr/bin/
mke2fs has to be updated.

After updating the above bin, could run the below command.
fastboot format:ext4:10000000 cache

Thanks,

Hi,

In my case adb remount is success with overlaysfs. But if I push any new files in vendor or system partition its getting lost after reboot.

Any idea on how to push/replace the files in vendor/system partition ?
