=============== ===============
The 'red' and the 'green' LEDs of the board should light up alternating with a This test will blink all available on-board LEDs, one after each other in an
500ms interval. If your board has only one LED (probably defined as LED_RED), endless loop. Each LED will light up once long, and twice short, where the long
you will see only this LED blink at 1Hz. If your board has no on-board LED, you interval is roughly 4 times as long as the short interval. The length of the
will see nothing. interval is not specified and differs for each platform.

========== ==========
All boards in RIOT define at least two macros for accessing two selected Running this test shows if all the direct access macros for all on-board LEDs
on-board LEDs directly. These are called LED_RED and LED_GREEN, independent if are working correctly (xx_ON, xx_OFF, xx_TOGGLE). This test is intentionally not
the actual color of those LED is red or green. using any timers, so it can also be used early on in the porting process, where
timers might not yet be available.
