Re: [Emc-developers] RPi5 + Raspbian + LinuxCNC latency tests - first impressions
None of those images were for the Rpi-5, I thought the RPi4 in the file name would made the obvious, but as this a topic about the 4 I guess there could be some confusion. As for the recent RPi5 image you tried does that have any issues with screen resolution? Is it stuck on a single resolution? Does it detect the display it's attached to ? These issues, as mentioned previously, a game stopper for myself. If they aren't an issue could you say what kind-brand-model display you're using ?

Re: [Emc-developers] RPi5 + Raspbian + LinuxCNC latency tests - first impressions
The kernel that has been used previously on the RPi4 has worked fine on the 5. The Foundation images for ALL versions of the RPi used the same kernel, I've booted the same kernel version on the Rpi4 and 5 so to say "solid preempt_rt kernel for the Pi5 which has not been possible previously" is not correct, as I've used the same kernel version and patches on both the 4 & 5 (tho built suit each platform), the bootloader decides which kernel image to boot based on the name of the kernel image file. If you need to remove-add-customise anything from the images you can mount them and then use qemu to chroot into the image and do what you need to do, this is how the bulk of the image is created. This I've mentioned before via email. Here are a few images I've done some post build "polishing" when installing the desktop I used xfce task as this installs a little more, mainly the network manager.

Re: [Emc-developers] RPi5 + Raspbian + LinuxCNC latency tests - first impressions
Linuxcnc only really needs one image, it's not really meant to be a General Purpose Distro, that is the image that has all that is required to get up and going. Anything else may cause confusion, as I've noticed some people can be a bit adverse to reading information or there can be a language issue. A developer will be able to get all the bits & pieces they need. In my opinion an image without a UI doesn't make much sense for Linuxcnc. And "normal" & "minimal" are quite subjective. When Rod and myself were discussing the building the building of images we had different ideas as to what was required, I opted for a more complete desktop where Rod just went for "what was required", although I did uninstall libreoffice to reduce download size. I also included the "gvfs" stuff, to make it easier to connect via sftp from the file manager to different machines. I didn't push the issue as Rod is the more Senior member, so what Rod went for was great, I just kept doing things my way for personal use.

There are a few differences, like the location of config.txt, locales can be a hit and miss trying to set them up, even when using the supplied menu-config utility. For the RPi5 the biggest issue is the display, for whatever reason when used with an RPi5 it appears the EDID information is not being read from the display\monior\clay-tablet\slate\cave-wall or whatever the user has connected up or there could be some "special sauce being missed". I tried a couple of different fixes, most related to the RPi4 as there was not a lot regarding this on the RPi5 and "non foundation images". This has been mentioned a few times on the forum. The solution I used was a "foundation image", compiled a suitable kernel and then built Linuxcnc packages from source. As is my preference I installed an XFCE desktop and used raspi-config to change from Wayland to X as the Wayland compatibility layer for X I found some what slow. Unfortunately due to no SPI driver for the RPi5 and not wanting to starting ripping things apart in the Mill's control box to get access to my mesa ethernet hardware the little Rpi5 is resting. Tho I do have a PCIe NVME board to try out. Tho I will say it is quiet the beast and does compile a kernel and Linuxcnc at quite a good clip, that's just with the SD card, I suspect other storage mediums may improve the "rate of clip".

Re: [Emc-developers] RPi5 + Raspbian + LinuxCNC latency tests-first impressions
The odroid has been running fine all year, no need to do anything. Maybe I wasn't clear, the J was retired a while ago when I started using the Odroid. I now have 2 options for the "roll my own" EPP board, the HP T610 plus or the retired J. There is no issue with Odroid. It is fine.

Ahhh I've given up on anything happening for the RPi5 regarding the SPI stuff. Going my own way with a "roll my own" EPP card, got a little HP T610 Plus that should be fine for running the '53 based Myford ML7\Super 7 abomination.

Re: [Emc-developers] RPi5 + Raspbian + LinuxCNC latency tests -first impressions
Gene are you after a PC image or a Pi image ? Or have you made a type with the amd64 bit ? I must admit with the "role your image utility" rod uses the locale things is a bit messy & seems to do what it wants. I've made images usingthe same method and it's felt a bit "hit & miss" getting the locale thing correct. Half the issue is a that you expect it to work like an RPi image but it's not based on any of the RPi images by "The Foundation", tho the kernel and some utilities come from there there does seem to be some "magic sauce" missing.

[Emc-developers] QEMU arm64 slave for buildbot
Hi all, I've recently been building and testing some Bookworm based Raspberry Pi4 images with consultation with Rodw over at the forum. I've gotten to a stage now where I am chroot into RPi4 root file system and build packages of Linuxcnc using QEMU suitable for installing om a Raspberry PI. I was just wondering whether this setup could be used as a buildbot slave to maybe help out.
