I had the same problems until I did a full erase of the chip before reflashing the board. Try that. I'm on mobile and don't remember the command exactly but do "pyocd -h" in a terminal and you will get the idea. Then reflash the board.Following my resent failures this is what I've done and where I am at now:
- Flashed the NVEM with the Remora firmware
- Installed Raspberry Pi OS (Legacy), so Buster 32 bit
- Installed xrdp to enable Remote Desktop
- Followed the guide to install LinuxCNC at remora-docs.readthedocs.io/en/latest/sof...nc-installation.html , but since I had issues with the Pi not booting after installing the realtime kernel, I instead installed 5.15.65-rt49 according to forum.linuxcnc.org/9-installing-linuxcnc...n-raspberry-pi-3b-pi .
- Installed the Remora NVEM component
- Followed Scott's videos to configure ethernet
- Flashed the basic config to the NVEM
- I am able to ping the NVEM at 10.10.10.10
- I am able to start LinuxCNC and get out of emergency stop
- I am not able to request movement. If I do, I get "joint [0-2] following error"
I really wan't to move on and reinstall the NVEM in my CNC and continue with configuring LinuxCNC, but I'm stuck with this error.

Hey! Thanks for the reply!

Might not solve your problems but worth a try

Unfortunately no, I had the original concept "working" on the STMF407 but it was just not fast enough to get the calculations done for all 6 axes within the servo thread period. The RT1052 is heaps faster.I wanted to say the following, if it would be possible to use Dma Stepgen with the nven with the stm207 and also with the 407

Hi Cakeslob,
GeremyL has been doing some great physical testing of the DMA stepgen. Chasing down missing steps, with one theory being the lack of a direction setup time.
The ability to set the direction setup time is now available.
Code:{ "Thread": "DMA", "Type": "DMAstepgen", "Comment": "X - Joint 0 step generator", "Joint Number": 0, "Step Pin": "P1_22", "Direction Pin": "P1_17", "Step Length": 2, "Step Space": 3, "Dir Setup": 2 }, Latest source has been pushed to the repo and a testing bin file as well. Can this be backported? It doesnt look like it should have to be DMA specific, but Im not too good with computers so I figured I would ask. Also, saw you had a new repo for remora-nv docs, do you think we needed a whole new repo for the nv docs? I just figured we could jam all the nvem specific parts within the hadrware specific pages. the rest of it seems pretty much the same so it looked like we could do it all as one. Here is what I had so far for ethernet branch, I used it when I was setting up my pico-dlx board. https://github.com/cakeslob/Remora-docs/tree/ethernet
