Hi,
Update to above, remora-ec500.hal revised to 'loadrt remora-eth-3.0' (and commented out mpg in remora-ec500.ini).
Linuxcnc starts with only the usual 'Unexpected realtime delay on task 0 with period 1000000'.

EC300 LEDs ON and understood are: SYSTEM 24V, IO COM+ and CONN.
EC300 LEDs ON and not understood are: OT4, OT6, OT7, OT9 & OT10, also spindle INDEX.

Toggling the E-stop turns the 'CONN' LED on/off; is this an indication of proper firmware function?

Now to try connecting stepper drivers.

Success!! Thank you Scott and all Remora contributors, the Zenith of home CNC for me is a low power SBC (RPi4) and a dedicated motion controller looking after the step/dir timing.

I believe all names should match name with chip,board from start:
xxx.bin to xxx JSON config.txt that you upload. Folders with correct files and compiled halcomponent according to board in linuxcnc machine folders.
remora-nv is for NVEM not ECxxx series.
Make sure you use correct repo files correct for your board version/model

hello,
I found an old version of debian buster I am trying to install remora on a NVEM rt1052
when I run the following command (sudo python -m pip install -U pyocd) I have an error message

Does uploading JSON require remora components installed with halcompile command.
Somehow I am unable to connect to board after uploading JSON config for stm32
This give me error due to incorrect pin assignment

I have try number of eth cables and devices. Since I have uploaded incorrect config I am unable to fix it.
I have uploaded new .bin with CMSIS but JSON config have stayed old.

Please help.

You dont need the remora component installed to run the config tool.

I dont know if there is a bootloader or anything on these chips, but writing the new firmware wont overwrite the config, you will probably need to do either a full chip erase, or erase the sectors where the config is stored.

I believe all names should match name with chip,board from start:
xxx.bin to xxx JSON config.txt that you upload. Folders with correct files and compiled halcomponent according to board in linuxcnc machine folders.

Make sure you use correct repo files correct for your board version/model

To a degree, they should match. I dont know all the names for this project, but I am under the impression that the STM32 versions and the RT1052 versions of the board share the same name.

remora-nv is for the stm32 versions
remora eth 3.0 is for the RT1052 versions

as far as I can tell

Ok I was wrong thinking this would default config but I have not found info on how erasing it can be done. I used MCUXide but not sure if there is option to use when flashing firmware so it remove bad config.
I have been through rpi3, rpi4, debian12 on linuxcnc pc and various repos to look for eth connection and failed greatly to access 10.10.10.10 ip which I managed before.
Now I have no idea where to find problem. RPI repo does not have buster release anymore therefore following manual on remora-docs.readthedocs.io/en/latest/sof...ry-pi-linuxcnc-image is near impossible.
command:sudo apt-get install linux-image-4.19.71-rt24-v7l+

don't work after all steps above in mentioned manual!

Sorry, I must have misunderstood. So you have the RT1052 but you loaded the stm32 json?

Im not firmiliar with the RT1052 version, but if its like the stm32 version, you probably need to do some kind of fullchip erase, but I dont know very much about the rt1052

For installing linuxcnc RPI image refere here. it is premade with linuxcnc installed.

remora-docs.readthedocs.io/en/latest/sof...ry-pi-linuxcnc-image

do this for installing Rpi linuxcnc, the other section is old and no longer used.
"Deprecated instructions preserved for posterity"

after you have a linuxcnc install working, you need to install the component depending on which board you are running

remora-docs.readthedocs.io/en/latest/sof...mp-installation.html

then you need to configure your ethernet ip

Hi need a little bit of assistance with my setup I'm just trying to test things right now, I have programmed my ec500 and can ping and also connect with Linuxcnc I have successfully fully uploaded my configuration but I am getting stuck with a (joint 0 following error) I am using the ec500-rt1052-DMA.txt and remora-ec500.HAL and .INI from the github.com/scottalford75/Remora-RT1052-c...CNC/remora-ec500-DMA folder and my joint velocity is higher than TRAJ max velocity as it is in the repository.

When I go to jog an Axis I get no movement but my Velocity jumps to 1248.0 and I get the joint following error
Any thoughts would be appreciated.
I think I might have resolved this or just found a different issue

Warren
