Hi there.
Can the linux kernel and norns image build on macos? Can I find some instructions on how to do it?
This is related to norns shield as usb host devices limit - #9 by Daniel_Gorgan, as I want to build the kernel with CONFIG_SND_DYNAMIC_MINORS=y. Has anyone attempted to do that?
Thank you.
Hi @tehn and thanks for the input.
I managed to build the images (seen here) but I’m not sure what to do next. I guess I should build a norns image using this and flash it to an sd card, but I’m not sure how to build the image. Any hint will be appreciated.
Thanks!
My typical workflow is to:
mkdir /mnt/norns
mount /dev/<sdcard-device><root partition> /mnt/norns - to mount the root filesystemmount /dev/<sdcard-device><boot partition> /mnt/norns/boot - to mount the boot filesystem/mnt/norns/
Note that we intentionally disable HDMI output so there is no way to debug boot/kernel failures unless the UART header is installed and a serial connection is setup.
Once upon a time you could get away with writing the kernel builder archive out right on top of the boot files of a running norns but with the rpi4 generations and/or the 5.10 kernel that now trashes the running system more often than not.
Thanks @ngwese. I flashed a sdcard and mounted it on linux using:
sudo mount /dev/sdb2 /mnt/norns
sudo mount /dev/sdb1 /mnt/norns/boot
ls on these folders shows:

Should I merge these folders or overwrite them? I see that lib/modules folder is quite different. I’m not sure how to proceed…
Thank you.
overwrite the folders and unmount
Sorry but it still doesn’t boot. The green light flashes 4 times and that’s about it. Any chance to debug something?

your config.txt likely does not match your hardware then.
download the correct image: Release norns 220306 · monome/norns-image · GitHub
and then make the generated config.txt match that of the downloaded image, except for updated kernel entry
Thank you so much for your help! I managed to do it and it really works. Now my norns can show up to 16 devices in DEVICES > MIDI menu. Here’s a video showing it all.
Maybe this is something which should be enabled by default? Do you accept PRs on monome/linux repository?
that’d be fine to PR, though I’m not expecting we’ll be releasing new kernel builds anytime in the near future.
what would be very helpful is if you’d possibly spend a moment documenting your process of building the kernel with extra steps and PR that to the readme of norns-kernel-builder
My trick was to actually have github build the kernel for me.
The issue was with dtoverlay=monome-snd-4270 line in boot/config.txt where I replaced it with 4271 (as it was in the original image which worked).
I will try to open PRs on both repos.
