Remora - ethernet NVEM / EC300 / EC500 cnc board

I think you have to remove BOOT->3.3V jumper. Just tasted with jumper and i'm not able to flash.

Yes, I've only ever had to use the boot button or jumper when I've locked up the firmware with bad code or not being able to connect the debug probe.

DMA Stepgen - beta testing

For those interested, DMA Stepgen is ready for beta testing. On the bench it's working nicely with bugs being found and fixed along the way. Appreciate some feedback on issues.

github.com/scottalford75/Remora-RT1052-c...t1052-2.0.0-beta.bin

The DMA stepgen is configured like below:

As you will see, there is now the ability to configure the step length and space settings. These are in multiples of 1 micro second (1000ns).

With a 1 micro second step length and space you will achieve 500 khz step rate! 

Of course, adjust your max velocity in your HAL setup to respect the max step rate achievable with your step setting.

God bless you scotta, I was on my way to give up with EC500, but with the last build everything work great, except TFTP, but I rebuild it with changed default JSON. Thanks for the great work you do. Ping is between 200-400 us, stepgen works perfect with no follow error. Continue to test but for now works perfect.

For the tftp error try
Sudo apt install python3-pip
Pip3 install tftpy

That did it for me. Sorry for the formatting but I'm on mobile but you get the idea.

Pip3 will install the python3 tftpy module. Pip will install only for the 2.7
