# (1-LED) Solid OFF: Bootloader running, or kernel hung (timer task stalled)

# (1-LED) Solid ON: Kernel hung (timer task stalled)
|

# (2-LED) Solid RED: Bootloader running, or kernel hung (timer task stalled)
|

# (2-LED) Solid YELLOW: Kernel hung (timer task stalled)

# 5Hz blink: preinit

# 10Hz blink: failsafe

# (1-LED) Heartbeat: normal operation
