The message "OS was not verified!" is shown in U-boot on Android BSP

If the error message which is at the bottom of this page is shown in U-boot,
there are two ways to avoid showing it.

  1. Re-flash Android BSP
  2. Remove string "avb" from bootcmd variable in U-boot

Log:

read_is_device_unlocked() ops returned that device is UNLOCKED
boot_device = 1
avb_vbmeta_image.c:187: ERROR: Hash does not match!
avb_slot_verify.c:618: ERROR: vbmeta_a: Error verifying vbmeta image: HASH_MISMATCH
avb_ab_flow() returned OK_WITH_VERIFICATION_ERROR
OS was not verified! Press any key to halt booting!..
