Gaining Bootloader Shell

The Amazon Tap implements a secure boot process, however a bootloader shell can be obtained by grounding the eMMC flash data pin while U-Boot is reading its own environmental variables into memory.

To access the bootloader shell.

  1. Connect to UART (keep your TX line disconnected!)
  2. Power on
  3. Wait for output over UART
  4. Ground resistor below the TP27 silkscreen
  5. U-Boot shell is available when presented with "=>"

The photo below illustrates the process.
