Description
Reference section
D1
Tri-color LED
– Driven by Target MCU. JP6 must be
shunted for +3.3V to be applied to D2 anode. The default
shunt for JP6 is a 0Ω resistor installed at JS17.
n/a
D4
Target MCU BOOT0_LED indicator. Reflects the state of
Target MCU P1_1. When the boot process fails, D1 will
toggle at a 1 Hz rate for 60 seconds. After 60 seconds,
the Target MCU is reset.
n/a
D5
Link2 MCU BOOT0_LED indicator. Reflects the state of
Link2 MCU P1_1. When the boot process fails, D1 will
toggle at a 1 Hz rate for 60 seconds. After 60 seconds,
the Link2 MCU is reset. It will be ON when the Link2
MCU is Booting using DFU (See description for JP6).
n/a
D8
Target MCU Power LED.
n/a
D9
Target MCU Reset LED
– this LED is on anytime the
Target RESETn is pulled low.
n/a
D13
Ethernet link active indication (controlled via LAN8729A)
n/a
D11
Ethernet 100Mbps indication (controlled via LAN8729A)
n/a
