One note--lcec_generic has a test that floats aren't larger than 32 bits. I've disabled that if we're using a double, but there's a chance that something under the hood will break. Again, testing.

It'd be kind of nice to have an EtherCAT test slave that runs on a Raspberry Pi (or similar) that we could use for testing this sort of thing. Then I could work it into my usual testing process.

Hi,
I found another small bug. Then I change a tool the icons of the desktop menu become visible (see picture below).

Please use Balena Etcher to install the image in this thread rpi-imager does not work
forum.linuxcnc.org/9-installing-linuxcnc...pberry-pi-4-5-images
i think we are good with the Pi 5 now except for sound. If anybody knows their way around kernel settings for sound, please let us know


 

Scott,
Please read the Linuxcnc downloads page.
Typing: sudo menu-config
allows you to set wifi and locale etc.

Configuring fixed ip address etc for ethernet card, can be done manually as described if you type: man hm2_eth

We removed networkmanger I had added it in and latency suffered on the pi4b

If you really need to use it, you can install synaptics: sudo apt install synaptic 
I prefer to search for the package names in Debian Package search packages.debian.org/index
and use sudo apt install package-name

When you say you don't have sound, this is  a known issue, one of the upstream guys was going to review that for me as its a limitation of their installer. Their first priority was to fix the compression settings so it can be installed with rpi-imager.

I don't think it will be wise to use sudo apt upgrade becasue we have a custom built PREEMPT_RT kernel we have built from source using a kernel version not in Debian Bookworm..

Note the ethercat repos are installed if you want to go that way.

Hi,

I am getting the following warning when doing a sudo apt-get update on my RPI 4 running bookworm:Hit:5 www.linuxcnc.org bookworm InRelease                        
Reading package lists... Done
W: Skipping acquire of configured file '2.9-rt/source/Sources' as repository 'www.linuxcnc.org bookworm InRelease' does not seem to provide it (sources.list entry misspelt?)I installed linuxcnc 2.9.2 according to  linuxcnc.org/docs/2.9/html/getting-start...lling_on_raspbian_12

uname -a: Linux raspberrypi 6.1.0-rpi7-rpi-v8 #1 SMP PREEMPT Debian 1:6.1.63-1+rpt1 (2023-11-24) aarch64

The following linuxcnc entries in my sources.list:

deb [arch=amd64,arm64 signed-by=/usr/share/keyrings/linuxcnc.gpg] www.linuxcnc.org/ bookworm base 2.9-uspace 2.9-rt
deb-src [arch=amd64,arm64 signed-by=/usr/share/keyrings/linuxcnc.gpg] www.linuxcnc.org/ bookworm base 2.9-uspace 2.9-rt

Do I need to update my sources.list?

Thanks
 

Balena works well.

Screen resolution works so much better than anything I have seen so far. Jitter is good and sim looks smooth.

Problems, I have no sound, no Wi-Fi, no network manager and no update manager.

Thank you for all the work.
Scott

Hi,
I have tested it a bit on my lathe with gmoccapy. So far so good. With my old iso I had some latency errors they are gone. The audio error on raspberry pi 5 persists.
And I can't move/rotate the gcode viewer with touchscreen.

Yes, balena works for me,too.

Great! Please test it out a bit and give me some feedback

It seems that we are using a slightly different compression method that the PI imager does not like.

Yes, balena works for me,too.

It appears that there is something about our image that the Rpi Imager does not like.
The guys are working on it.
Could you please try burning with Balena Etcher? etcher.balena.io/
This burnt and validated the image for me.
 

Hi,
here is the translation:

The input file is not a valid disk image.
The file size 4723000000 bytes is not a multiple of 512 bytes

Best and a happy new year

COuld you translate that to English please? I will report it to the upstream guys

Hi guys, could you guys with the PI's please test these images for me and provide some feedback
These are refreshes of my earlier 2.9.1 images.
They both use the latest PREMPT_RT 6.1.69 kernel, and Debian Bookworm

2.9.2 for Raspberry Pi 4b/400

Note 2.93 images include the 6.6.44 kernel, better  screen support on the Pi5 and ethercat repostories installed. See the sticky in the ethercat section on how to install.

Also, those of you with the Pi5, have you had any issues with sound. One user reported he had no sound but the HDMI output is a bit poblematic. The images do include pulseaudio.

Just released version 1.2.0 to PyPi with support for Raspberry Pi 5!

This release brings furthermore:

• An updated watchdog module with an enable pin. This enable pin is HIGH as long the watchdog is happy. It will go LOW when the watchdog bites, for example when the communication gets disrupted. This enable pin can be used to control / disable buffers to bring the machine to a safe state. When recompiling a card, modification of the configuration file is required.
• Several bug-fixes:
  • in the CLI (correct detection of 64-bit RPi);
  • PWM does not generate errors / warning at compilation;
  • pin numbering of HUB75HAT has been corrected (connectors were mirrored);
  • resolved error with GPIO when there are only inputs or outputs defined..
