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
