Uboot Partition Aml Dtb Verify Patition Error Result

To diagnose, you need a serial connection to the UART pins of the Amlogic board (usually 115200 baud, 8N1). Boot the device and observe the log.

Example of a full error log:

U-Boot 2015.01-g03dd89b (Jan 10 2020 - 14:32:11 +0800)

DRAM:  2 GiB
MMC:   sd/emmc: 1
Partition: dtb not found
aml_dtb: verify partition dtb error result: -1
** File not found /dtb.img **

Uboot Partition Aml Dtb Verify Patition Error Result -22

Key information:

  • Read header bytes:
  • Compare expected image format:
  • Check stored checksum/hash:
  • Verify keys and signatures:
  • Inspect hardware health:
  • Test alternate sources:
  • Recreate or restore DTB:
  • Enable/Increase logging:
  • Check U-Boot version and patches:

    • You’ll need to access the U-Boot console via a USB-to-TTL serial adapter (3.3V logic). Once connected, interrupt the boot by pressing Space or Ctrl+C when you see Hit any key to stop autoboot.

    Run these diagnostic commands:

    # List all partitions
mmc list
part list mmc 0

    Recommendation:
    Unless you have UART access and U-Boot shell experience, the safest fix is to reflash the complete original firmware using Amlogic’s USB Burning Tool or mask ROM mode short pins.
