After OSUpdate device not booting from slot B even after marking slot B as active.

[swetabh suman]

I am stuck with a scenario, where the OS update get success/completed then battery is removed immidiately within 1-2 sec.

In this case the update_engine completes its updating job and marking the next slot as active.But the problem is even if the slot B is marked as active, in the next boot device does not boots from slot B, rather it boots from slot a.

Below are the logs of the update engine completing its update process.

Hi Swetabh,

Can you try manually changing the active slot using bootctl command.

Here the details of the command:

=====================================================

bootctl - command-line wrapper for the boot HAL.

Usage:

  bootctl COMMAND

Commands:

  bootctl hal-info                       - Show info about boot_control HAL used.

  bootctl get-number-slots               - Prints number of slots.

  bootctl get-current-slot               - Prints currently running SLOT.

  bootctl mark-boot-successful           - Mark current slot as GOOD.

  bootctl set-active-boot-slot SLOT      - On next boot, load and execute SLOT.

  bootctl set-slot-as-unbootable SLOT    - Mark SLOT as invalid.

  bootctl is-slot-bootable SLOT          - Returns 0 only if SLOT is bootable.

  bootctl is-slot-marked-successful SLOT - Returns 0 only if SLOT is marked GOOD.

  bootctl get-suffix SLOT                - Prints suffix for SLOT.

SLOT parameter is the zero-based slot-number.
