[To be provided]
LED1:
- OFF means that the OS is still initializing. Initialization is very fast so
if you see this at all, it probably means that the system is hanging up
somewhere in the initialization phases.
- ON means that the OS completed initialization.
LED2:
- ON/OFF toggles means that various events are happening.
- GLowing: LED2 is turned on and off on every interrupt so even timer interrupts
should cause LED2 to glow faintly in the normal case.
- Flashing. If the LED2 is flashing at about 1Hz, that means that a crash
has occurred. If CONFIG_ARCH_STACKDUMP=y, you will get some diagnostic
information on the console to help debug what happened.

LED1 LED2 Meaning
----- -------- --------------------------------------------------------------------
OFF OFF Still initializing and there is no interrupt activity.
Initialization is very fast so if you see this, it probably means
that the system is hung up somewhere in the initialization phases.
OFF Glowing Still initializing (see above) but taking interrupts.
OFF ON This would mean that (1) initialization did not complete but the
software is hung, perhaps in an infinite loop, somewhere inside
of an interrupt handler.
OFF Flashing Ooops! We crashed before finishing initialization.
ON OFF The system has completed initialization, but is apparently not taking
any interrupts.
ON Glowing This is the normal healthy state: The OS successfully initialized
and is taking interrupts.
ON ON This would mean that (1) the OS complete initialization, but (2)
the software is hung, perhaps in an infinite loop, somewhere inside
of a signal or interrupt handler.
ON Flashing Ooops! We crashed sometime after initialization.
