The examples in the repo are not up-to-date, however those in the documentation are. I will remove the examples from the repo (except one or two) and make sure they work. For a full list of configurations, see the examples section.
For the install_litex
error: you've found a nice caveat. The problem is that the files have to be cloned in your user folder, but you cannot install it with the --user
option from pip. Will resolve it by adding another option --venv
, which will do your manual steps. Also, I will add documentation on how to install manually.

Hi Peter, don't know what to say... a simple thank you ain't enough to express how grateful I am for your support, let alone this cool project you've impressively facilitate for the community. The Documentation was already beyond amazing, just needed a 'linux illiterates' tweak, which you've kindly done I've seen! Cheers man 👍😎

F'ing EPIC!! Let's play this. Thanks, Peter. Happy for you to close this. I'll catch you in the Discussion Section or forum when I'll struggle (lol) to get the hal & ini sorted. Aiming for a closed loop (3 glass scales + 2 ABZ encoders) for a 4-axis mill.

Great to hear that you are willing to try Litex-CNC. The setup I currently work with is indeed the 5A-75E, but for my Raspberry Pi based setup I'm switching to the 5A-75B in combination with a hat and running on SPI.
Issues installing driver
Concerning the driver: does sudo
not work at all on your setup, or does install_driver
throw errors at you when using sudo
?
Most likely you require privileges to modify the contents of your LinuxCNC installation, so sudo
is required. When running sudo
however, you also get all environment settings of that super user, which breaks things. You can solve this with the following command:
sudo -E env PATH=$PATH litexcnc install_driver
This is an issue with the documentation. I can see this command is in the repo, however it is not listed (yet) at the documentation.
Could you let me know whether this resolves your issue concerning the driver?
Issue concerning installing Litex
The --user
-tag is not working at this moment, see also #47. This has been resolved, but that version is not officially released yet on PyPi. I will make a release this evening, so you can test whether this resolves your problem.
from litex-cnc.
For install_toolchain
there are options too!
litexcnc install_toolchain --help
gives
Usage: litexcnc install_toolchain [OPTIONS]
Installs the Toolchain for ECP5 (oss-cad-suite)
Options:
--user
-a, --architecture [arm|arm64|x64]
-os, --os [darwin|linux|windows]
--help Show this message and exit.
For your system the correct command for installing the toolchain will be:
- for a desktop:
litexcnc install_toolchain --user --architecture x64 --os linux
- for a Raspberry Pi on Debian 12 (Bookworm):
litexcnc install_toolchain --user --architecture arm64 --os linux
- for a Raspberry Pi on Debian 10 (Buster):
litexcnc install_toolchain --user --architecture arm --os linux
With the upcoming release (working on it), you don't necessarily have to provide --architecture
and --os
, as this is derived from the system itself.
NOTE
You might have to restart your system to put the toolchain on path correctly.

Version 1.0.3 has been released. You can install it with:
pip3 install -U litexcnc[cli]
Let me know whether it works, then I will close this issue. For more support on drafting your configuration for the card, you can always ask in the discussions.
from litex-cnc.
The examples have been resolved.
For the install_litex
I don't think we need an extra option; the option has been there the whole time. In your case the command would have been:
litexcnc install_litex --directory ~
Which installs it in your HOME
-directory, thus circumventing any permissions. And it installs it without the --user
as required for venv. I do agree, the documentation has to be better.
from litex-cnc.
'too name a few' suggests you experience more issues, can you also list your other issues here ?
from litex-cnc.
Hi Peter. Too cool, thanks so much for the tweaked sudo tip, this worked and installed the driver flawlessly!
Among other installation failures are $ litexcnc install_litex and $ litexcnc install_toolchain. Below are my install steps on a stock Debian 12 with Python 3.11. Pretty sure this will all makes sense to you once you've seen the attached screengrabs. Let me know if you need me to test anything at my end, all up for making this work for 'novice gurus'.
$ sudo apt install python3-pip python3.11-venv
$ python3 -m venv /home/cnc/LiteX-CNC
$ source /home/cnc/LiteX-CNC/bin/activate
$ cd /home/cnc/LiteX-CNC
$ pip install litexcnc[cli]
$ sudo -E env PATH=$PATH litexcnc install_driver
$ litexcnc install_litex (comment about "Issue concerning installing Litex" noted though, I'll try again tomorrow)
from litex-cnc.
Hi Peter. Sweet, the toolchain installs with the given options, thanks for highlighting this for us. However the LiteX dependency still fails with the following errors:
$ litexcnc install_litex
PermissionError: [Errno 13] Permission denied: '/opt/litex'
$ litexcnc install_litex --user
ERROR: Can not perform a '--user' install. User site-packages are not visible in this virtualenv.
The workaround is to install it manually, for now, however I have no idea if this is the way you anticipated it and/or want to document it:
$ mkdir LiteX
$ cd LiteX
$ wget https://raw.githubusercontent.com/enjoy-digital/litex/master/litex_setup.py
$ python3 litex_setup.py --init --install
$ cd ..
from litex-cnc.
Regardless of what appears as a successful dependencies install, it is still impossible to build a bin file. See steps and error below:
$ git clone https://github.com/Peter-van-Tol/LiteX-CNC.git
$ cd LiteX-CNC
$ litexcnc build_firmware examples/5a-75e.json --build
raise ValueError("Field board_type
is requierd.")
ValueError: Field board_type
is requierd.
Note: I've edited the examples/5a-75e.json and added at the top: "board_type": "5A-75E v7.1",
and now this error shows up:
for index in range(len(kwargs['modules'])):
~~~~~~^^^^^^^^^^^
KeyError: 'modules'
And so I'm completely lost. Certainly not working at my end obviously because my abilities as a user and knowledge doesn't help me too much. I'll see if I can find time to browse through those 60'ish pages of the linuxcnc forum and see if I can find hints as to what's going on. In a meantime if you know what's happening I'd love to hear what I'm doing wrong.
I appreciate the help and support so far. Too kind already.
from litex-cnc.
Quick update:
Peter, I've managed to build a *.json example taken from member "deroj" on the forum.
https://forum.linuxcnc.org/27-driver-boards/44422-colorcnc-colorlight-5a-75e-5a-75b-as-fpga-controller-board?start=610#281360
And that's good news! However not so much for new 'users' (aka non-linux experts like myself). As a suggestion, I certainly see additional details to be put into the documentation "installation" section. And of course updating the /examples/ with some that works to prevent any confusions as to why nothing works.
Apart from that, I am super excited about your project! One of the coolest out there I had the chance to take on, and so I'd like to pass my gratitude for what you've done for us. Top notch!! I look forward getting these buffers desoldered and in/out signals scoped (not really haha). All good fun nonetheless, thank you Peter.
from litex-cnc.
I've improved the documentation. Could you check whether you would have found the information you needed to install the driver, Litex, and toolchain when looking at the latest documentation?
from litex-cnc.
Cool! I will add this as a tutorial!
