hello.

I try install but error hardware "cpu no supported" but my cpu is a raspberrypi4 b... what's going on with this?

Does anyone else have a tip as to what I'm doing wrong? I haven't found anything on the net until now. STLink with the instructions here from the thread didn't work, stlink with the hex file here from the thread flashed successfully, according to the display. NVEM v5 - Flashing not possible. I tried with DAP-link, J-Link, ST-Link v2 standard, firmware update and firmware from github. The result was the same every time, regardless of whether it was from the Raspberry Pi or with Windows 10. Either the board is fundamentally different, which I don't believe since it was recognized, or the programmers from AliExpress are all unusable.

the error messages are:
C STLink error (9): Get IDCODE error [__main__]
C Unexpected ACK value (0) returned by probe [__main__]
C Memory transfer fault (Unspecified error.) [__main__]
 

I am running LinuxCNC 2.9.3 on Raspberry Pi4. Installed using official LinuxCNC image. Its working properly.
I want to upgrade this installation to latest master branch. 
How can I upgrade to master branch? I searched a lot but didn't find any answer.

I recommend watching this video: . It might give you a good idea of what to look for.

Additionally, try finding your product information—such as the vendor ID and product ID—on the vendor’s website. It's also important to verify whether your drive supports the CIA402 standard.

Were you able to successfully read the encoder data? That could be a good starting point to ensure communication is established.

if possible share your problem in detail.

Linuxcnc works fine with Raspberry Pi 5, but when I watch it on the GUI, the positions are a bit delayed. When I use it with a PC, there is no problem. It communicates with 6 servo drivers and a PLC. It would probably be better if its speed increased a bit.

How can we overclock the Raspberry Pi 5, which currently has Debian installed on it? I want it to be faster. Are there any commands that will increase the CPU voltage and frequency? Or what can I do to make it faster? I installed a fan cooler, what else can be done?

I am using the image shared by rodw. The problem does not persist now, I have solved it. If you want, I can share pictures of how I did it tomorrow.

I am using the image shared by Rodw for Raspberry Pi 5 in the ethercat installation topic.

Are you using the supplied LinuxCNC RPi image? If so it sounds like we might need to fix something in the setup. A CNC machine shouldn't screen-blank.

There is a whole thread about screen blanking here: forums.raspberrypi.com/viewtopic.php?p=433728#p433728

(Basically there are several things that can blank the screen)

If it locks the system, requiring a password, then it won't be the always-tricksy "dpms"

What sort of step rates are you getting through the GPIO? (And which driver are you using?)

Good morning and thank you for your reply.

As you may have noticed, I am the name here. I have tried to download the image that my colleagues have posted, I have tried the Linux CNC standard and I am not able to move forward. My driver is a Lichuan LC10E. Is there any basic step-by-step guide to help me achieve my goal? Thank you very much in advance!

At a guess, the image you have used is 32 bit and the Pi4b is 64 bit
Please use the image on the linuxcnc downloads page and not the comments arouns seting wifi etc.
 

hellow sr. hakan.

Congratulations on your post. I had an initial problem.

I downloaded the image and used the raspberrypi image to save it and it didn't start. Mine is a raspberrypi4b.

O erro "CPU 0 not supported"

Hello, nice work.

I'm installing a 5 axis XYZBC machine driven by a berak out with a parallel port --> I want to switch to an ethernet port and raspberry pi 4. I want to add position sensor feedback at least on the B&C axes.
I'm trying to install linuxcnc 2.9.3 on my raspberry Pi 4 under raspbian. Impossible to compile/install the RT patch . see that you have a version “Linux pi 6.6.44-rt39 #1 SMP PREEMPT_RT Mon Aug 12 21:10:13 AEST 2024 aarch64 GNU/Linux” .
Can you help me with this installation?

Thanks for your help
 

Hi everybody, as the name suggests this is a guide for people wanting to install and start playing around with Riocore.
For those that don't know anything about Riocore you can read through the original thread :

www.forum.linuxcnc.org/18-computer/49142...d-on-fpga-ice40-ecp5

This guide is aimed at people that aren't linux guru's, that want to have a try at this awesome LinuxCNC software/hardware and that might struggle like I did...for weeks...to install it and get it going.

Credit to meister, the guy behind it all, he has done an impressive job of getting all this going.

Another credit to ColdTurkey, his idea of using the LinuxCNC live install to setup software/hardware in the Remora thread is what I based my approach on, this way everybody has the closest starting point possible.

This guide will focus on getting everything going for the Gowin Tang Nano FPGA, and meister's Tangoboard, once you have this going you can select other FPGA's and boards as you wish. You will most likely need to change the FPGA programming side of things with other FPGA's.

OK lets begin...
This is for a normal PC, I will have a look at a Raspberry Pi install sooner or later hopefully.
Download and install the latest live install of Linuxcnc, then open a terminal

sudo apt install git
open firefox, skip all start steps, start browsing, google search gowin eda
open page, (first link for me) create account, only email and password required
once logged in, select support, then Gowin EDA Home, then Download Gowin EDA
select software for Linux tab
select the one that says education, (click over to the right)
  (at the time of writing this it is the 7th option down)
open File system, navigate to Downloads, right click and select extract to
click on the little folder icon and select Home then extract
go to the folder in file system, right click rename folder to gowin
    its easier to type out later
open terminal, enter these one at a time :  
git clone github.com/multigcs/riocore.git
sudo apt install python3-pip
sudo apt install python3-yaml
sudo apt install python3-graphviz
sudo apt install openfpgaloader
sudo apt install python3-pyqtgraph

That last one takes a while to install

Now we setup the USB programming :
in terminal still,
cd gowin/Programmer/bin
once you are in that folder type and enter :
sudo ./Gowin_USB_Cable_Installer.sh
sudo make

reboot machine

open terminal

type and enter :
export PATH=$PATH:home/your_user_name/gowin/IDE/bin

in my case my user account is "me" so I type:

export PATH=$PATH:/home/me/gowin/IDE/bin
export PATH=$PATH:/home/me/riocore/bin

change to the riocore directory
cd riocore

now type
PYTHONPATH=. bin/rio-setup riocore/configs/Tangoboard/config.json

This should get you up and running, now there is lots to learn about setting up a machine but hopefully this will take the heartache out of starting.

Now things can be a little weird, I believe the Tang Nano needs to be plugged in at reboot, sometimes it won't flash properly, I cannot honestly say I have got it 100% sorted but if anybody finds a better solution we can edit this to suit.

Good luck
Russell.
