Windows on ARM

@MarkG What i mean is loading the actual system.
RIght now it seems (to me from the image provided) that it doesn’t get you into FOS. It loads, just gets stuck?
-
@Tom-Elliott
Yes I think that’s correct if I’m correct that getting into FOS would mean the kernel started to boot. What you see there is what happens immediately after I make a selection from the FOG menu. It downloads the kernel and the init. The next thing that appears onscreen is what you see there, and then after a couple of seconds it reboots. -
@george1421 Thanks for such a fast and detailed response. Yes I fully understand that we are in uncharted waters and that few people have this hardware yet so I am happy to be usefull to the community with these devices for as long as I can keep them before they are provisioned.
I will attempt to do this after the weekend and report back my results.
How do I go about this step? “Get that file name and key it into the dhcp server/s option 67 value”

So that leaves me with a few notes already:
Tom, I did some testing back in 2021 trying to get a rpi to pxe boot. I never did but here is what I found with FOG and a few changes that needed to happen: https://forums.fogproject.org/topic/14959/raspberry-pi-4-unable-to-pxe-boot
I’m only adding this here for reference.

The question back to you is what is your dhcp server for the imaging network? That is where you would set the value for the boot loader. BUT the OP of this thread has already done that and has proven how to get into the FOG iPXE menu, so the inits work. He has already figured out the arch type (11) for the dhcp server (what i needed the tcpdump/wireshark pcap for). Right now we have an issue with the fos linux (engine that clones disks) starting up. If I remember right the person that developed the FOG arm kernel was building it for a cortex CPU. It might not have all of the bits in it needed to boot the dell/lenovo. This is nothing unsolvable, we just need to find out about the processors in your system(s) and look at the kernel configs. This hardware is so new there aren’t a lot of info out there about it.
It would be interesting to see if you could find a live linux OS for the arm cpus and get that to boot. We could then reverse engineer the kernel settings for that live boot OS. (just thinking out loud)

class “UEFI-ARM64” {
match if substring(option vendor-class-identifier, 0, 20) = “PXEClient:Arch:00011”;
filename “arm64-efi/snponly.efi”;
}Well done working out the hard bits. It sounds like there needs to be some fog ui updates and we need to get that FOS kernel to boot cleanly. In the FOG Global configuration settings. There should be a field for log level, set that to 7 to see if there are any additional log entries that gets displayed. The default value of 0 or 4 masks most of the kernel messages. The level 7 is only used for debugging.
Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG!

FWIW It looks like snapdragon support will first be available in linux kernel 6.11
https://www.phoronix.com/news/Qualcomm-Adreno-X1-85-GPU-Linux
additional linux support docs

I will be getting a snapdragon laptop on Monday for FOG/FOS testing.
It looks like kernel 6.11 will most likely be released Sunday but there already is a release candidate that I could build to test with.@Tom-Elliott Implemented some changes to support ARM by default on the 1.6-alpha branch of FOG.
I am currently porting it over to the 1.5 dev-branch -
@rodluz On that laptop, what is the processor model? From what I’m gathering (I’m a bit ignorant on arm systems) but snapdragon is akin to the word pentium. There are a few models that fit behind that banner. Is your system the x elite or one of the older processors like the 850?
-
@george1421 I’m getting an X Plus, X1P-64-100 (10 cores up to 3.4GHz, NPU integrated). I’ll be getting an X Elite probably a few weeks later but from my understanding, they are the same generation.
-
@george1421 This is all very encouraging! I tried kernel debug level 7 but there was no additional information.
-
@rodluz I have 2 X-Elite’s one running Hyper-V which I am hoping to do the majority of testing in and one which is yet to be opened incase the business decides to return them.
edit: X Elite - X1E80100

@george1421 I was not thinking when I asked that, but have not got the laptops to the FOG menu, I tried to register but immediately failed as expected. Interestingly when I tried from a VM on the ARM Laptop I got a blank FOG menu and an error “synchronous exception at 0x00000000DE6A82DC”.
We are on FOG 1.5.10 and we are currently updating our UBUNTU to 24.04 LTS and will then install Kernel 6.11. I will try this afternoon to get linux to build on hyperV and then attempt to instal it on the second laptop.
-
@george1421 I have run the install for UBUNTU server 24.04.1 LTS ARM64 and that gives me the same error as MarkG,
I am going to continue to hunt for a live OS that will boot.

Just be aware the needed kernel is for fos linux and not the fog server’s host OS.

Please keep testing, but I’m going to suspect the current class of linux kernels will need to be updated to 6.11 to support these new processors. Its the linux kernel devs that need to have one of these devices in their hands to debug. We’ll see mainstream linux support soon on this. This isn’t really a fog problem, but a linux kernel issue. We’ll get there when one of the fog developers have one of these systems soon too.

@george1421 is this the kernel that is downloaded and installed inside the fog web interface? I’m currently working through a tftp authentication issue to upgrade this.
-
@stokehall said in Windows on ARM:

yes. but the file bzImage does go into /tftpboot it goes into /var/www/fog/service/ipxe directory.
You can also manually download the kernels from here: https://github.com/FOGProject/fos/releases and then place them in the path.

@george1421 I have had some small success on testing and with Oracular Desktop from 16th Sept I have managed to get it to the language selection on instal with the GUI, however it is not taking any inputs so it is definitely not a working image but it is closer than anything else so far. I have not been able to get any Linux to get any further than a small underscore on physical hardware but over VM I am able to reach the language. I can see that the system has not crashed, as the clock is updating although only if i close and reopen the VM.
This was accessed from here but I have not managed to get the 190924 version to work yet and cannot see the one I used listed: https://cdimage.ubuntu.com/daily-live/current/
I fixed my TFTP issues and upgraded the kernel but as expected it is still not going any further in FOG.
-
@stokehall Thank you for the update. I didn’t think Ubuntu was going to start using kernel 6.11 for their 24.10 release, but it seems like they are, so I’ll take a look over the weekend.
