Possible to get a clear image of the PHY. It looks to be the same as the earlier NVEM's but it would be good to know.

 
Sorry Scott, on re-reading that I now interpret you are asking for a better image of the PHY? If so could you explain to this ancient layman what you mean please? image missing /media/kunena/emoticons/smile.png
 

Fairly sure its the ethernet chip here he is looking for 

Maybe a few extra close up pics of the chips that are a bit blurry if possible. Then we can post links to all their data sheets.

Yes, some good clear images of front and back of board for this part of the board. What I did for the EC500 was to overlay the back and front images in CAD, aligning the vias so that I could then trace the circuit. Some really clear closeup photos would help.

Looked at J-Link OB and very quickly realized I am out of my depth!
Happy to invest if it helps, any recommendations Scott?

Me too, I've been struggling with the STM32H743, let alone now learning the NXP tool chain.... like anything, one step at a time. Hopefully the J-link is the right programming adaptor as it will take 3 weeks to get to me. A week after the EC300 is due to arrive.

Starting a parts list of the EC300 here with links to all the data sheets.
