Remora - ethernet NVEM / EC300 / EC500 cnc board

Nothing special, connected as usual. Just erase and then firmware reflash.

I had the ACK error show up on a modified STlink after having used it multiple times within the previous hour, went back to a standard ST and had no further issues.

You can try leaving the STlink and EC500 depowered for a while. I came back the day after I had the issue and got it to flash once more before the error came back again.

Where you able to flash on rt1052 with standard STlink? Mine is modified to CMSIS-DAP firmware, maybe I can use my unmodified one just for erasing, I'm gonna try. Thanks again

Yeah man, Standard STlink works fine using the method I posted.

The biggest issue I found with linux and pyocd is that it doesn't give permission for pyocd to access the usb device. There is a step in my post to allow this. It may work with versions of linux outside of the linuxcnc distro

I focused on getting it working using the linuxcnc install because I figured it's what the majority of us would be using and it's nice to make everything work using just one computer. Good luck.

There is no reason to use Linuxcnc installation for anything except drive the CNC machine.
There are many Linux distros better suitable for programming microcontrollers.
You can install many OS on one computer, and use this, that is better for you do at the moment.
Notice, many tools (especially python based) are version sensitive and can works only with specific distro.

Just an idea, is there a way we can flash our boards using the same method they use. When I bricked my stm32 version in mach3, they sent me an utility to flash the board back to original, is there a way to make it work for remora? I attached the utility

And yet there are still heaps of people in this thread struggling with flashing Remora to the board and no clear start to finish documentation that works 100% of the time. A lot of people don't want more than one operating system on their computer, especially if they are only going to use it once for this job only. Why learn about more distros of linux when we can just use linuxcnc since that is what we have already and it also works?

If there is a better way of doing it and since you obviously have more experience than I do, how about you contribute and write a guide to help all the people having issues?
