To run litexcnc in your poetry environment, please use:

sudo -E env PATH=$PATH poetry run litexcnc install_driver
 
Sorry...This doesn´t work either.
oj@VMLinuxCNC:~$ sudo -E env PATH=$PATH poetry run litexcnc install_driver

This error is due to an error in your project. Can you share the location of you repository or a zip-file with your code, the I can correct the error for you.

Also...
I implemented the aforementioned improvements in Litex-CNC. When pulling the latest version from this GitHub branch  you can now load extra modules and directly connect to the FPGA, for example with:
loadrt extra_modules="toolerator" connections="eth:10.0.0.10:1234"

The above statement will load the extra module toolerator  and will connect to a FPGA using:
  • ethernet / etherbone protocol (this is the only supported protocol at this moment);
  • the ip-address 10.0.0.10 (adjust this to the value in your config json);
  • the port 1234 (when the port is 1234, this can be omitted, as 1234 is the default).
One step closer to releasing version 1.0.0 of LitexCNC

Don't think it is an error in my project because I did not add one.
I am just not familiar with poetry and/or your workflow

Deleted litexcnc from the python site-package folder.
Reinstalled it with pip (0.9.0a5)
Did the poetry add git+http://......
Then sudo ... poetry run litexcnc....

Wth the template I might have a mistake, which causes this behavior.

With he reinstall: did it work?

No it didn't...
There is a simple thing I am not doing right I think.
But I don't know where to look.
Do I have to clone the branch into a certain folder or path?
Or only poetry add?
I tried to clone the branch with git clone.
Then went into the cloned LiteX-CNC folder.
Then the poetry run command kind of worked. But it also did not include any of the "litexcnc_...py" modules

Here is the terminal...compilation failed because I did not use "sudo".
But it shows the behaviour.
Only when I am in the LiteX-CNC folder, the poetry command kind of works

for module in ModuleBaseModel.__subclasses__():
            print("Module")
            for file in module.driver_files:
                click.echo(f"Copying file '{os.path.basename(file)}'")
                shutil.copy2(file, os.path.join(temp_dir, os.path.basename(file)))
                if re.search("litexcnc_.*\.c", os.path.basename(file)):
                    modules.append(os.path.basename(file))

It seems that this for.loop do not find any files.
I added "print("Module") to check if there is any output.
Maybe the path is not right? What should be in "os.path.basename(file)"  ?

I really hope this project gain attention and we can have good documentation for the ordinary user can build the machine with these board.
In future will be good to implemente driver in linuxcnc and some configuration tool will be game changer for a lot users.

The project is still at the mercy of hardware vendors that make these boards for signage.

The board is almost totally reverse-engineered, but without such a bulk production one won't get this affordable price
