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. Or a J dual core celeron board that gathering dust after jumping onto the Odroid bandwagon.

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 Humm, apparently rpspi.ko is still part of linuxcnc. My lathe is running just fine but the gpio driver it is running on to drive a mesa 7i90HD is not this new one but the rpspi.ko that Bertho Stultans wrote back in 2017 or 2018, then rewrote in 2020 for the rpi4b when I got an rpi4b. And he was nice enough 4 yeas ago, and could probably update it for rpi5's if asked and has the data for the version in the rpi5. Running it from my buster config, it runs well and claims its master 2.10-pre which would be an armhf build. But its ONLY my config copied back into the sdcard after Rod's image was written to it. Its the linuxcnc Rod put in the image. So, what do I need to do to put the the /etc/apt/sources.list.d/linuxcnc.list for linuxcnc back on the arm64 master build version AND get and install the proper keyfiles so apt will accept it? The install instructs stops coming forward at buster. Definitely out of date now. 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. Expected.

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. Yes they are very against anything realtime. Mention it the 3rd time and get banned from thier forum for life. So when I first did this in about late 2017 on an rpi3b, I built my own 4.19-rt kernel but had no clue how to install it. So I pulled a tarball together that was only the lib and /boot stuff from those 2 directories of the build, which I actually did on the pi. The plain, no gzip tarball is about 28 megs, and I installed it by mounting the sd-card in a reader, and using mc, copied the lib subdir of the tarball to the /lib of the card, and the same with the /boot stuff. Put the card back in the pi's socket, it booted my kernel & ran that way till the rpi4 came out, 2 years or so. Since I do my building on an SSD, much faster than the SD card and it mounted to the rpi4 with a usb to sata cable, installing on the rpi4 was essentially a wash, rinse and repeat but much faster with the 4's usb 3 sockets. That was in Feb 2020. Its been running an updated master of linuxcnc since. And doing stuff it could not do when assembled in Chicago in the late '40's. But the image now on the card has the first 2.9 release and I'd like to go back to master & continue with what I call the canary in the coal mine duties for linuxcnc. When I get that done, trixie will probably be out, and the buster on my 3 wintel machines is getting stale so I'll bring them up to trixie, if I don't miss roll call first, a possibility since my next b-day will be the 90th. Got hardware keeping me alive now, pacemaker and a TAVR valve in my heart. 5 or 6 years left on each ;o)> So I goto linuxcnx.org & hunt up the 291 announcement, and the first thing I see when I find the build bot link is to install its key which is different foom the other one. But on execing the get key phrase, I'm greeted with: cnc@rpi4:/etc$ sudo apt-key adv --keyserver hkp://keys.openpgp.org --recv-key EF1B07FEE0EE663E Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8)).

So how is this done now?
