Remora - ethernet NVEM / EC300 / EC500 cnc board

Guys, new NVEMs has a new scheme and a new main chip - iMX RT1052.

Great to hear you are getting a response from the board. I assume that LinuxCNC will come out of eStop and that you can run a gcode confirming communication with the board is good.

Have you used the latest firmware github.com/scottalford75/Remora-EC500/tree/main/Firmware ? Also, I've be caught out not having the switch in the "nv" position.

Thanks for sharing. This confirms the move away from STM chips (probably due to shortages) and that the EC300 that I've purchased will have the same. With the MAPBGA package reverse engineering the circuit is going to be fun....

MX_Master, is there an available programming / debug pads on the back? Any experience with the NXP? Which programming adaptor? Back on the learning curve again...

This photo (new NVEM board) isn't mine. It's other guy's controller. He gave me some other photos, but there's no photos of the PCB's back. I think new board has a debug pins too. Why not? I have no NXP experience. But this chip has a 600MHz CPU, so your project can run faster on it (120MHz vs 600MHz).
