It's really helpful to have the ability to dump BCB block for debugging A/B logic on the board supported this partition schema.
Command 'bcb ab_dump' prints all fields of bootloader_control struct including slot_metadata for all presented slots.
Output example:
board# bcb ab_dump ubi 0#misc Read 512 bytes from volume misc to 000000000bf07580 Read 512 bytes from volume misc to 000000000bf42f40 Bootloader Control: [misc] Active Slot: _a Magic Number: 0x42414342 Version: 1 Number of Slots: 2 Recovery Tries Remaining: 0 CRC: 0x2c8b50bc (Valid)
Slot[0] Metadata: - Priority: 15 - Tries Remaining: 0 - Successful Boot: 1 - Verity Corrupted: 0
Slot[1] Metadata: - Priority: 14 - Tries Remaining: 7 - Successful Boot: 0 - Verity Corrupted: 0
