@TOLP i tried to install litexcnc yesterday with the original ISO LinuxcncBuster 2.8.0 and i can‘t get it to work. So I tried the excellent manual from tommylight (I think)to install mint21 (for me no worries because i run the tests on a virtual machine) with linuxcnc2.9 - and it all works like a charm! The only thing what you have maybe to install is „pip“ and maybe „git“ after that you can install litexcnc very easily! Thanks again for the help!

I'm trying to follow the steps in README.md from github.com/Peter-van-Tol/LiteX-CNC
I get this error on the first step on my arch linux system:

[cedric@cedric ~]$ pip install litexcnc
Defaulting to user installation because normal site-packages is not writeable
ERROR: Could not find a version that satisfies the requirement litexcnc (from versions: none)
ERROR: No matching distribution found for litexcnc
[cedric@cedric ~]$ uname -a
Linux cedric 6.0.11-arch1-1 #1 SMP PREEMPT_DYNAMIC Fri, 02 Dec 2022 17:25:31 +0000 x86_64 GNU/Linux

Next I try the same command on my linuxcnc installation:

$ sudo apt-get install python3-pip
$ pip3 install litexcnc
Collecting litexcnc
Could not install packages due to an EnvironmentError: 404 Client Error: Not Found for url: pypi.org/simple/litexcnc/

$ sudo apt-get install python-pip
$ pip install litexcnc
Collecting litexcnc
Could not install packages due to an EnvironmentError: 404 Client Error: Not Found for url: pypi.org/simple/litexcnc/
$ uname -a
Linux virt-cnc 4.19.0-21-rt-amd64 #1 SMP PREEMPT RT Debian 4.19.249-2 (2022-06-30) x86_64 GNU/Linux

$ cat /etc/issue
Debian GNU/Linux 10 \n \l

What am I doing wrong?

@DePrutser: at this moment litexcncis not yet available on the official PyPi.org. The pre-release is available at test.pypi.org. To install it, please use this command:

Code:

pip install --extra-index-url https://test.pypi.org/simple/ litexcnc[cli]

I will update the README.md to show the correct command. For documentation, please refer ReadTheDocs .

@TOLP - Hello again - So the Litex drivers are already installed - also a board 5a75b v8.0 is flashed - (and ping went good) when I try halrun -> loadrt litexcnc i get this error

Code:

cnc@cnc-LIFEBOOK-E744:~$ halrun
halcmd: loadrt litexcnc
Note: Using POSIX realtime
litexcnc: dlopen: /usr/lib/linuxcnc/modules/litexcnc.so: undefined symbol: json_object_array_length
<stdin>:1: waitpid failed /usr/bin/rtapi_app litexcnc
<stdin>:1: /usr/bin/rtapi_app exited without becoming ready
<stdin>:1: insmod for litexcnc failed, returned -1
halcmd: exit
Note: Using POSIX realtime

So i think when i reinstall the litex_driver i can see that the position250 is the board name? is there a maximum lengh maybe? (I Only Uses 6 letters....)

Code:

  250 |         rtapi_snprintf(fpga->name, sizeof(fpga->name), json_object_get_string(board_name));
      |         ^~~~~~~~~~~~~~

Code:

My System:
[code]Linux cnc-LIFEBOOK-E744 6.0.0-6-rt-amd64 #1 SMP PREEMPT_RT Debian 6.0.12-1 (2022-12-09) x86_64 x86_64 x86_64 GNU/Linux

LinuxCNC Version
2.9

I have to check, did you use:

Code:

litexcnc install_driver

or (in case of permission denied error)

Code:

sudo litexcnc install_driver

If this is the case, I have to dive into the code. At this moment I cannot verify this, as I'm rebuilding my system, will be Monday to have this done.

I‘ve done it with sudo (so that everything goes to $PATH) No worries - I have time!image missing /media/kunena/emoticons/cool.png
