Re: [Emc-developers] RPi5 + Raspbian + LinuxCNC latency tests-first impressions
The Pi image is forked from here https://github.com/pyavitz/rpi-img-builder It is based on the official Raspberry Pi kernel https://github.com/raspberrypi/linux (rpi-6.1-y branch ) with Debian Bookworm wrapped around it. It uses a cross compilation environment so it gets built on x86 hardware. It has a good scripting environment that allows us to install linuxcnc as part of the build process.. The download page desperately needs a paragraph outlining the username (cnc) and password (cnc) and the need to run sudo menu-config to complete the build. I have no idea where the source is for that page or I would do a PR. Builds for both the pi4b/400 and the pi5 are supported by setting the board parameter at build time. The Pi4 version supports the gpiod driver which is documented. https://linuxcnc.org/docs/stable/html/drivers/hal_gpio.html Preempt_rt patches are supported but the challenge here is always to match the kernel being built with the patched RT version. We can specify the commit to pull so we can match to the RT patch but currently, the latest kernels that have been patched have not been merged into the pi source. As far as spi and gpio on the pi5 go, that board was never in scope. It is up to the devs to devise appropriate drivers as its out of scope of the installer.

Has anyone had a chance to look into the SPI issue with the RPi5 ? I've thrown mine back into it's box and a random location on shelf as ATM it's kinda useless for what I wanted it for.

Re: [Emc-developers] RPi5 + Raspbian + LinuxCNC latency tests - first impressions
Thank you, Rod! Will definitely try that one. We need to find some official instructions for the RPi4/5 installation, I suggest. I looked through our documentation today but did not find anything beyond the use of RPi GPIOs. After Seb's comment on using the wrong kernel I had a bit of a facepalm moment - thank you, Seb! Then I installed a regular arm64-rt kernel but that then ruined the RPi setup, so after a reboot I had no more Wifi and (worse) the ventilator was a max, even though the same wrong stock kernel was booting after the reboot. Sounds like flashing a new SD card to me. And it also sounds like a guarantee to lose all our new LinuxCNC users on an RPi. We can certainly do a lot via our custom images for which we could come up with an RPi5 variant, but preferably we'd have someone in an official position to prepare the RPi5-rt kernels for everyone, as part of the Raspbian or Debian distribution, not just us for ourselves. Is there anyone on this list who would know whom to ask? Best, Steffen > Gesendet: Mittwoch, 27.
