I think many posts in this thread are completely unrelated to the topic I started it with.
My idea was to compare the performance of the Raspbian Bookworm (and not the Debian) on Pi4 and Pi5....
ITs difficult for users to compare the products until they have a robust installation method for the pi5. But it has been reported latency is much improved.

The OP has describe a robust installation method within the opening couple of posts. Having tested both methods for the RPi5, the Raspbian OS based method appears to be the better setup.

[code][code]Regarding this...  is it understood why the latency was so much better in the RPi 5 test, than the RPi 4?  Is this purely a result of improved processor performance, or is there some other underlying reason?  (And, has that result been reproduced?)

Unless I'm misunderstanding, I think that latency is quite a bit better than I currently get on my 10 y.o. AMD PC, which implies I could potentially replace it (and its parallel port) directly with an RPi 5 and its gpio pins.  Which I confess excites me a bit.  :-)

If you look at the thread announcing this release the first post gives clear instructions how to fix this.

I gave up on the official iso the other day as it could not load the firmware for my Ethernet card, even tho when booting to a live session it did. I did also mention it.
As to the raspi firmware that is a bug in the installer from Debian. I don’t know why the issue isn’t mentioned on the download page, but the download also mentions the RPi 5 image supports SPI, which it doesn’t.
So to install the latest Debian version and linuxcnc 2.9.2 on my x86 system I used the Debian netinst image, installed the need kernel manually, used the script mentioned in the docs to install linuxcnc, for less frustrating than trying to use the official image.
Now I’m no slouch in this area, I’ve made my own respin of Mint for Linuxcnc, made my own Raspberry Pi images and messed around with Mesa firmware to run on a couple of Xilinx dev boards. This was absolutely the worst experience trying to install linuxcnc on a machine. It amazes me newbies actually get anywhere.

Cannot find file for:Min_svarv.hal

This file needs to be in the same folder as your ini and main Hal files.
Could be a typo in your ini file.

If you see a line stating it can’t find a file or a pin doesn’t exist that is the error. Mostly it will be a typo somewhere.

I think it's pretty clear that if I download LinuxCNC_2.9.2-amd64.hybrid.iso from official the link at linuxcnc.org/downloads/ , and the installation fails because unnecessary Raspberry Pi firmware is inoperable on my x86 PC, then it's a bug.

Perhaps it's an unavoidable bug, or very inconvenient to fix. But the release is over 2 months old. Plenty of time for there to be a note on the downloads page with a warning, and the (trivial) fix.

Hi here are the whole error file

 

Provide more information, typically the whole debug message. As there is very very little information there.

HI i am trying to use rapberry pi 5 and Linuxcnc and i made sucsess with my instalation of 3 axis mill config but when I make a new setup for my lathe I get this mesege .

Can anyone point me in the right direction so I can try to solve this

check in with this guy, he installed it recently on a pi zero

We need to mash this file into our drivers, as this is the new RPi5 spi driver
github.com/raspberrypi/linux/blob/rpi-6....rs/spi/spi-dw-mmio.c

RPi5 doesnt use the same broadcom IO stuff as previous models, they made a their own IO chip. instead of bcm2835 controlling the SPI, the new chip used this designware driver

Thank you very much for your answer. I will try to switch to the Bookworm system, but I can only use a 32-bit system because using a 64-bit system on the Zero-2 W causes the core to hang and fail to start after installing preempt-rt.

1GHz and 512MB......does you instructor not like you ?Once you have it installed, if you can run a config all power to you.If the instructor asks you to machine this, maybe you should get them some help. 

 

Sorry, newbie, but there is one question from the experience of forum members, because time has passed, and experience is power.
Is the Raspberry Pi4 network controller with Ethercat stable?
If so, on which versions of Linuxcnc and on which Linux kernel?
Thank you all for your responses and feedback.
