ColorCNC Colorlight 5A-75E/5A-75B as FPGA controller board

If you use the main branch you should be ok.
That's a known issue with the 11-add-external-extensions-to-litexcnc branch. It happens on both 2.8 & 2.9 branches of Linuxcnc.

The best idea will be to keep a watch on this thread:
github.com/Peter-van-Tol/LiteX-CNC/issues/28

Dredging this one out of the archives -- how are people getting on with this hardware/firmware solution? I'd love to play around with this on a 3020  router with your usual steppers, limit sensors, EMO, and maybe a 0-10V for spindle. Is there a config that works for this use case?

Thanks

Pete's been making some great progress. He's working on a SPI version for the RPi for those that want that option.
I'm just uploading an image for the RPi with LitexCNC drivers and tools to build firmware, yes it does include Linuxcnc v2.9.
If you wander over to github.com/Peter-van-Tol/LiteX-CNC and read the discussions section you'll find out more.

Yes. It is working very good. Maybe perfect

I use it for my lathe and for a 3 axis mill.
pwm output is used to generate 0-10V signal for the vfd of the mill.

on the lathe I use a 10.000ppr spindle encoder with high frequency optocouplers, which works perfect.
G76, G33 cycles and constant surface speed - no problems.
Finished already about 400 parts on my lathe. And this with a buggy version of litexcnc. And this bug is solved now
Peter did a great job the last weeks

Please fell free to download my maschine setup.
It includes the setup for my lathe.
There are 4 stepgens available.
2 Encoders with A, B, Z inputs
3 PWM channels
general GPIOs

Communication to VFD via modbus, mb2hal component.
in the firmware folder are the config JSON and the prebuilt bitfile.
It uses colorlight 5A-75B board
Ip address 192.168.178.150

You can add or change to your needs. Think this is a good basic to start.

Thank you both for the update! (and Peter, for that matter)

I took the development of Litex-CNC to a new topic .Feel free to post suggestions and questions in that topic, or post them on the Github Discussions .

Board models  RV901  ,  5A-75E  .
There are also models for  MRV336  ,  7i96  .

I hope this will be useful to some. 

Hi All,

Please help me!
I setup fresh install Linuxcnc 2.9.1.  (on laptop i7 x64)
Linux cnc 6.1.0-13-rt-amd64 #1 SMP PREEMPT_RT Debian 6.1.55-1 (2023-09-29) x86_64 GNU/Linux
I would like setup Litexcnc, but it dosen't work. If runing litexcnc install_toolchain command, i get this error:

INFO: Successfully installed Litex in '/opt/litex'
INFO: Auto-detected os linux.
INFO: Auto-detected architecture i386.
ERROR: OSS-Cad-Suite does not support `i386` architecture.
ERROR: Please use a different system to build the firmware.

What can be the problem?

(sorry my bad english)
