Well there is an image here crying out for testing. Its based on the official 2.9.1 image for the PI 4B just compiled for the different BCM2112 board.It should work based on cornhlio's comments.

After booting this image, I am greeted by the Debian login screen. What is the username and password?

You'll have to dive into the RP1 as the IO has been moved off the BCM2712, the RPi4 had the IO on the BCM2711.

I had a bit of play but decided to move to another setup.

It would be great if you could point me to some appropriate build instructions. I can look at the driver.  I'm plenty familiar with building Linux, but I'd love to have a pointer to the exactly correct repos.  I haven't easily found this on this forum yet.

Should be ok.
Haven’t tested it myself.

Hi Cornholio, Stupid question- Lack of I/O support wont affect the 5's ability to run an ethernet card? (I have one on the way, still trying to decide what machine i want to use to drive it) Just my luck that there would be some weird conflict that means its a no-go.

The driver will need a rewrite, more than likely, due to the I\O being moved to the RP1 chip. So if you want to get into some driver coding go for it.

I can spend some time on this. Can we start a DM conversation? I've built Linux deployments before.

Don't malign MQTT to quickly. Its the underlying rechnology  in OPC UA's PubSub.
You have to remember that CNC is a very small subset of the fieldbus world so what we are looking for is not necessarilly what industrial automation engineers want.

Its not necessary to use public MQTT brokers, you can run up Mosquitto broker on Debian from the Debian repositories and host it in house on any linux box. I have done this. One industrial application I have explored is in warehousing where a packing station sends weights and dimensions from a ESP32 device to a MQTT broker and the ERP system can subscribe to that topic and receive detailed shpping data for audit purposes. I have started work on such a system that incorporates a low cost bluetooth tape measure. DHL lost a parcel on me recently and asked me if I had CCTV on my loading dock!

I don't see using Intel NIC's is  a limitation. there is a reason why Beckhof exclusively  uses Intel NIC's in their Ethercat techology.

In my home application, the MQTT broker is hosted on a Raspberry Pi that is also running Home Assistant. HA manages the GUI and controls all number of things around my home.

The terminal of debian 12 xfce in raspberry pi 4 does not open and wifi does not appear. RPI 4 model B 4GB 

Still waiting on SPI patches. Not too sure how much traction it will get. Will probably need someone to join in and make some noise. I've lodged an issue on github, but no responses.

Maybe someone may like to ask a question on the emc mailing, as I can't do that myself. And the reasons why are not up for discussion.

I installed this image (drive.google.com/file/d/1H_q0Ra-27ZDOhqu...x1f/view?usp=sharing) and it boots on my Pi5. Latency seems much better than Pi4. Is this the most recent thing?  I thought I saw something about SPI patches?

Hi.
This Links don´t work  !!!
i need Install Linuxcnc 2.10 , where I see the .deb File ?

Thanks

At the moment these links are available:
(tested on Debian Bookworm)
linuxcnc-uspace_2.10.0~pre0_arm64.deb
linuxcnc-uspace-dev_2.10.0~pre0_arm64.deb 

The new .deb files, updated to 1 December 2023, can be found in the file linuxcnc_2.10.0~pre0_arm64.zip  at this link. 

linuxcnc_2.10.0~pre0_arm64.zip

This version works on both 
- Pi 4 ( forum.linuxcnc.org/9-installing-linuxcnc...-pi-5?start=0#285240)
and 
- Pi 5 (forum.linuxcnc.org/9-installing-linuxcnc...-pi-5?start=0#285243)
with 
Raspberry Pi OS with desktop
Release date: October 10th 2023
System: 64-bit
Kernel version: 6.1
Debian version: 12 (bookworm)

I have encountered various weird issues since installing LinuxCNC 2.9.1 on my raspberry 4.
I have a previous thread about it here www.forum.linuxcnc.org/39-pncconf/50549-...nd-mesa-7i96?start=0 more related to PnCConf issues. I figure this is more gmoccappy related so a new thread seemed more reasonable.

Problem 1:
Everytime I edit a program, the window rescales/becomes bigger. After editing a program ~10 times, it's now so big I can't even reach the edit button.
After restarting LinuxCNC everything is back to normal and I can afford myself another ~10 edits.. Any idea what could cause this/how to fix?

Problem 2:
Everytime there's an error, I get an extra error window complaining that gmocapy can't find or can't play a sound. No idea where to even start troubleshooting this one.

Problem 3:
I have reoccuring issues switching from MDI to jog mode. It seems I get stuck in either.
I start LinuxCNC, enable machine and jogging works but I cannot type in MDI mode. I have to right click and then leftclick in MDI to be able to type anything at all. If I only leftclick it selects the field but it's like the keyboard doesn't work.
Once I can type in MDI, the jogging no longer work, even if I change to jogging or program screen/menu.
Only way to make jogging work again is to disable and enable the machine, which makes MDI not work. And around it goes...
Any ideas what could cause this, how to fix, where to look etc?

Any help is much appreciated!

I only needed this one activated. Now everything works.

Hello. I'm new to the forum. During the day I'm an embedded firmware guy. I've built products using the RPi4 (CM4) and an Olimex Lime board. I want to use LinuxCNC to control an ornamental lathe. I've got an RPi5 here now, as well as a Mesa 7c81 with an RPi4 on its back. I know I have more questions than I can post right now, but I look forward to learning more here. I'm particularly interested in how the RPi5 port is coming.

Here's the result of the latency plot on the 4G RPi4b running the LinuxCNC 2.9.1 Debian 12 Bookworm PREEMPT-RT ISO.  Doesn't look too good,  Is this normal?  We're planning to use DM542 style drivers, so maybe it doesn't have to be perfect, but...  I guess I should try the RTAI based one.  Or maybe I should just jump into the RPi5 project?
