Ethernet LEDs (LED1–2)
When is lit solid, it indicates that the SMSC LAN8700 chip (
LED2
detects a valid link. When transmit or receive activity is sensed,
flashes as an activity indicator. For more information on the LEDs, refer
to the LAN8700 chip data sheet provided by the product manufacturer.
GPIO LEDs (LED3–5)
Three LEDs connect to three general-purpose I/O pins of the processor
(see Table 2-13). The LEDs are active high and are lit by writing a
correct programmable flag signal.

Reset LED (LED7)

When is lit, it indicates that the master reset of all major ICs is

Batt GD LED (LED8)

When is lit (green), it indicates that the BQ27500 fuel gauge (
