Remora - ethernet NVEM / EC300 / EC500 cnc board

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 image missing /media/kunena/emoticons/shocked.png

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

To give an idea of what will help work out the IO. Using Rog's earlier photo's we get this the result below. A rule / scale in X and Y is the photo would also help scaling and stretching the images to get them to line up. This is going to be challenging... anyone remove solder mask of a board before? Being able to electrically trace this would also be beneficial.

 

If it is a dry film solder mask then it's likely polyethylene . You can try soaking it in xylene. If that doesn't loosen it then it might be an epoxy that will require some abrasive for removal.
