SPWF01SA LINK, ACT, and PWR LEDs

Hi all,

Following the schematics for the

 and the schematics for the

http://www.st.com/content/st_com/en/products/evaluation-tools/solution-evaluation-tools/communication-and-connectivity-solution-eval-boards/steval-idw001v1.html

 where the LEDs are connecting from the pins to ground. There is a new schematic (

http://www.st.com/content/st_com/en/products/evaluation-tools/solution-evaluation-tools/computer-and-peripherals-solution-eval-boards/steval-3dp001v1.html

) that I have just encountered that has these said LEDs are connecting to the pins from a 3.3V source. Which one of these schematics are correct?

I am having the issue where the LINK LED goes off after it makes a successful link. This does not seem to be correct and it would seem that the link LED should light up once a successful link occurs.

It would seem that the new schematic

(

STEVAL-3DP001V1

) 

has the LEDs correct.

Any insight into this issue would be greatly appreciated.
