DP83TC812EVM-MC: LED Meaning

Faruk Kilavuz

Part Number: DP83TC812EVM-MC

Tool/software:

Hello,

When I connect the DP83TC812EVM board to my custom development board, only LED_0 (D3) turns on. Under normal conditions, both D2 and D3 used to light up together. I am not sure why this is happening.
Please note that I am using the EVM board in master mode.

What is the reason of this issue?

Best Regards,

Faruk

    Hi Faruk,

    Is link up? Please read register 0x1 bit[2].

    Note that when the jumper on J2 is moved positions, you must click the reset button after. This re-samples the active-low/active-high state of the LED, in order to correctly operate the LEDs. 

    Thanks,

    David
