   6 # (1-LED) Solid OFF:    Bootloader running, or kernel hung (timer task stalled)
   7 # (1-LED) Solid ON:     Kernel hung (timer task stalled)
   8 # (2-LED) Solid RED:    Bootloader running, or kernel hung (timer task stalled)
   9 # (2-LED) Solid YELLOW: Kernel hung (timer task stalled)

  11 # 10Hz blink:           failsafe
  12 # (1-LED) Heartbeat:    normal operation
