Remora - ethernet NVEM / EC300 / EC500 cnc board

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?

 

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.

Here is a good idea for taking good close up shots of electronics boards:

Hi Scott,
I am lost. After flashing the new Firmware it is not able to ping the EC500.
Flashing the old firmware, still the same error with the nvmpg.
Sorry for this, but i need help to solve the problem.
Thx

Hi Christian, have you checked that your network adaptor is configured correctly to have an IP address within the same sub net 10.10.10.xx? Assuming you are not going through a router, When you plug the network cable into the controller board and run the ifconfig command from terminal do you see that your adaptor has an IP address?

If you have a good IP address and still no luck pinging, I'd then move on to doing a full chip erase and reflash the firmware. 

Hi Scott,
ip address is 10.10.10.1. So i did a full chip erase and reflashed the firmware from this " github.com/scottalford75/Remora-EC500/tree/main/Firmware ". A ping on 10.10.10.10 says host unreachable. So i erased the chip once again an flashed the firmware from " github.com/scottalford75/Remora-Novusun/...are/Remora-EC500.bin " And the ping on 10.10.10.10 has good results. But there is still no change with the nvmpg with this version of firmware. I don't know what I'm doing wrong. I am very sorry for causing you such inconveniences.

Christian, 

A few more things to check. Below is my wiring which is known to work. RX <--> TX.

 

Have you uncommented the line in the INI file to enable the NVMPG?
 

OK these are the three I see as blurred, first is the PHY one.
Second is the three chips to the left of the DC/DC in my original, third is the two chips to the top right of the DC/DC.
 
 
 

I'll borrow my wife's iPhone 13 pro tomorrow and set up lighting so that the text is is better contrasted, and I will do the reverse side of the board.
And I will share a high resolution version from my own forums where I allow 4K

Thanks Rog. The PHY is the same as the earlier NVEM's.
