Remora - ethernet NVEM / EC300 / EC500 cnc board

Thank you but I've already followed that, it was very helpful . Unfortunately There is no word about connection timeout. I've ordered rs232 to usb converter to have a look what is really going on with my board, it should be here tomorrow, hopefully nvem will tell me something more. Meanwhile if anyone had similar issue or know how to fix it, please share

lpkkk, ping it when its not plugged in, to make sure nothing pings back

I've tried today connect rs232 to usb to see some more debug but I've only see garbage. I've followed connection wiring from first page of this forum topic. I've tried on windows and Linux, same result. I've tried minicom, putty. I've tried to change speed from 115200 to 9600 and still nothing. My settings were 115200,8,1.

I've tried also to erase the firmware using pyocd and flash it again. Same result : I can ping nvem board but I cannot upload config. Neither with script and tftp itself.

I've tried to ping my card without cable plugged in and as expected it didn't replied anything. So it's correct. 

Update, my rs232 probe works now, it was just a wiring issue :

But transfer config still don't work, and probe doesn't show anything than on that image above.

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

lpkkk, upload your screenshots to the forum and not that external site
