Remora - ethernet NVEM / EC300 / EC500 cnc board

Here is one more option to connect to the RT1052 - i.MX RT Flashloader. Available on the nxp.com and fully documented  

Hallo
Ich habe ein Nvem v2 bestellt und einen Nvem v5 erhalten.
Der Prozessor ist ein MIMXRT 1052.
Meine Frage ist ob es möglich ist
Remora ohne Änderungen zu flashen.
Vielen Dank
Dieter

Unfortunately, not yet. Work to support the RT1052 chip has only just started.

Some more research, Flashloader and MCUBootUtility rely on the Serial Download mode through UART / USB when the board is booted in that mode by pulling Boot 0 pin high. I thought that the push button would serve this purpose. I've tried to get a response from the board through the RS232 serial port without success. This mode does rely on the default pins (pads) for the UART to be used, but we have no way of telling the connections without removing the RT1050. 

If the board has been configured this way this would be the most straight forward way to program the board as all is needed is a USB to RS232 adaptor. There is a second serial port for the MPG which I did not try.

We have 4 debug pins on the PCB, we are using only 3 (clk, io, gnd), what is for the last pin? The old NVEM board uses this last pin as 3.3V power source. New board can't be powered using this pin. So, maybe this uses for something special.

I still can't use the solder station at the moment. Can't make a wiring scheme.

It's connected to the voltage supervisor manual reset. The open solder pads a suspect are for the reset pin. Maybe part of their programming sequence to be able to reset the board..
