Remora - ethernet NVEM / EC300 / EC500 cnc board

Bumped into this, with all the reverse engineering going on might be useful to someone.
If not, let me know so i can remove it.

Cool, the new NVEM has external QSPI flash. Hopefully we can read using the i.MX RT Flashloader or NXP-MCUBootUtility.

I have now set up Linuxcnc again. Still, Linuxcnc works until a key is pressed on the NVMPG. I started linuxcnc from the terminal and it says the ethernet connection was lost. Once the EC500 has been de-energized and energized again, Linuxcnc continues to run without any problems until a key is pressed on the NWMPG. So the NVMPG seems to be interfering with the Ethernet connection.
Hi Christian, sounds like the behaviour of the earlier firmware. I've cleaned up my Github so that only the latest tested firmware is there. I've tested this firmware with my NVMPG and it's working as expected.

Hi Scott,

You are my hero. With the new firmware everything works as it should. Terrific. Now it can go on. Thank you very much for your work, your development and your support


Can you confirm iff the 0-10 volt is working?

So at this stage I'm not sure if this is good or bad but my NVEM "V2" has arrived and by the looks of it has the NXP IMXRT1052 chip...

Hi Scott, i will Check, but IT will Take some time. Bei Back top Test next week

Great to hear that you are up and running. Does your board look like mine or the "newer" version with the PWM to analogue chip? If it has the chip then the 0 - 10V should also work as it's using the same code as the NVEM.
 

Hi Scott,

I checked the PWM signal today. Apparently it doesn't work. I connected a 9volt block battery to Gnd and Vso and measured in Com. Everything is displayed correctly in the Hal Show, however, the measured value between Vso and Com does not change. It is constantly at 8.7 volts. Is my measurement method correct?
