LEDs
====
The STM3240G-EVAL board has four LEDs labeled. Usage of these LEDs is defined
in include/board.h and src/up_leds.c. They are encoded as follows:
SYMBOL Meaning LED1* LED2 LED3 LED4
------------------- ----------------------- ------- ------- ------- ------
LED_STARTED NuttX has been started ON OFF OFF OFF
LED_HEAPALLOCATE Heap has been allocated OFF ON OFF OFF
LED_IRQSENABLED Interrupts enabled ON ON OFF OFF
LED_STACKCREATED Idle stack created OFF OFF ON OFF
LED_INIRQ In an interrupt** ON N/C N/C OFF
LED_SIGNAL In a signal handler*** N/C ON N/C OFF
LED_ASSERTION An assertion failed ON ON N/C OFF
LED_PANIC The system has crashed N/C N/C N/C ON
LED_IDLE STM32 is is sleep mode (Optional, not used)
* If LED1, LED2, LED3 are statically on, then NuttX probably failed to boot
and these LEDs will give you some indication of where the failure was
** The normal state is LED3 ON and LED1 faintly glowing. This faint glow
is because of timer interupts that result in the LED being illuminated
on a small proportion of the time.
*** LED2 may also flicker normally if signals are processed.
