Remora - ethernet NVEM / EC300 / EC500 cnc board

Channel conflict was the issue. Bug fix release now available in the repo. Tested with standard stepgen and DMA stepgen with NVMPG.

Please share any issues. Thanks

One question, I'm studying the Remora-EC500-DMAstepgen, but I don't have any signal of pulses, could you tell me if in your tests, you were able to pulse the motors with DMA and this configuration? If so, could you tell me why this configuration is not happening? github.com/scottalford75/Remora-EC500-DMAstepgen

Hi all, hi scotta,
I reflashed my EC500 with the newest firmware to check if the NVMPG now works.
After reflashing LinuxCNC doesn't connect anymore. The EC500 doesn't respond to pings either.
I wanted to erase the EC500 to reflash it from new, but erase doesn't work anymore.
Issuing this command:
pyocd erase --target mimxrt1050_quadspi --mass
returns this error message:
0000718 C No ACK received [__main__]
I use a DAP Link btw.

I flashed the newest firmware to a second EC500, and now this one seems to bricked also.
I can't erase nor re-flash both of them anymore.
How can I un-brick them?

regards, hanskuster
 

How to fix timeout error during uploading config for nvem board?
Ping 10.10.10.10 went OK

That repo is only for sharing of development work done on the STM32 for a DMA stepgen. The algorithm and DMA works but the STM32 was not fast enough to generate the step patterns. The only working DMA stepgen in for the RT1052 based boards.

I'd resort back to MCUXpresso. When I've had trouble with bad firmware / flashing I've been able to recover the board by powering on while the probe is trying to connect.
