I've flashed remora-rt1052-nvem-0.2.1.bin, is that the right bin? 

probably not, but I dont think you are working out of the correct repo

github.com/scottalford75/Remora-RT1052-cpp/tree/main/Firmware

I've took it from here :
github.com/scottalford75/Remora-RT1052/tree/main/firmware

There is a firmware mentioned by me and it looks like it's been made for nvem board. Scott could you please explain which one is correct for nvem boards?

Cakeslob is spot on.

The latest firmware that supports the NVEM / EC300 and EC500 is this repo.

github.com/scottalford75/Remora-RT1052-cpp

The version you have used is very old original firmware and it didn't have the configuration upload capability.

Latest firmware is github.com/scottalford75/Remora-RT1052-c...ora-rt1052-3.1.3.bin

Thank you Scott for verifying. I've tried with 3.1.3 but after flashing I've got an error in rs232 debug (attached). And the board stopped responding to ping. So I've tried 3.1.2 but now board stopped displaying any debug info and I cannot reflash it because of another error from pyocd (attached). 

Looks like you successfully loaded the config....
Where did you get that config file? It is for a different board.

Load the one from the repository the firmware was in, and in the future, dont use anything outside of this repo

You may have to do a full chip erase to remove the wrong one. I think there are some instructions on how to do a full chip erase somewhere in the thread.

I've took it from here : (full)
github.com/scottalford75/Remora-NVEM/tre...%2Fremora-nvem-basic

I've done sometimes full chip erase,
I will try to erase it then put 1.3.3 with config you advised. But I'm not sure why at the moment I'm not getting anything from rs232

Today I've tried again and board seems to be empty, there is no eth connection. 3 diods are on. I cannot flash any firmware with stlink2.
Have you got any ideas how to fix it?

I'm not sure is my stlink is still good. I've tried to update firmware on stlink with their software and it shows firmware corrupted error 

Update :

I believe my stlink stopped working fine. I've used nanoDaplink and there was still no answer from the nvem. Finally I've pushed (and keep it pressed) reset button on nvem, then start flashing with pyocd. When I started pyocd I've released reset button and whole process went fine from there. It was flashed with remora 3.1.3. Later I've connected ethernet and tried to ping. One of the leds on nvem went off and my ping was succefull. Then I've used this config :

github.com/scottalford75/Remora-RT1052-c...NC%2Fnvem-rt1052.txt

And it was all good. Previously I've used by mistake basic and full config from here :

github.com/scottalford75/Remora-NVEM/blo...vem-basic-config.txt

Which I believe was not for RT1052 version of nvem board. DON'T USE THIS CONFIG. 


Quick install eth component and everything works perfectly. I can move 3 connected axis with this linuxcnc config :

github.com/scottalford75/Remora-RT1052-c...Fremora-rt1052-basic

But this Linux cnc config is only for 3 axes. Do I have to manually set my 4th axis? 

Next step will be adding limit switches, one for each axis (except 4th). Maybe this evening I will find some time.
