at the moment I only have this snippet to patch the kernel, but I haven’t tested it
boot.kernelPatches = [{
name = "patches_for_Banana_r3";
patch = pkgs.fetchpatch {
url = "https://github.com/frank-w/BPI-Router-Linux/compare/fbe58b8..379c024.patch";
hash = "sha256-+dkorhIe3PlhK+xUycoAsssu7BywiaWyZfecXq5p2P0=";
};
}];
nixos.iso contains these dtbs. As I understand they are built as described in the kernel. Are they correct if booting via uboot?

so the extlinux.conf file should be on the boot partition, right?
What should be there? For now I only have this one which was generated for nixos:
# Generated file, all changes will be lost on nixos-rebuild!
# Change this to e.g. nixos-42 to temporarily boot to an older configuration.

Will it just work if I put it into the boot partition?
So I tried also removing u-boot.bin to force direct initialization atf->kernel but then I got:

Though the file is there and its checksum is correct.
It cannot find the file Image inside the root of the boot partition.
You have not specified any dtb in the extlinux.conf
Use the dtb I supplied. If it works then experiment with others. Otherwise I can’t say why it doesn’t work.
I also think that linux image won’t work…
You could just use my script and build an archlinux image. There you can see exactly what you need and how it looks like. Then read [BPI-R3] Imagebuilder R3 Archlinux
I think you can use the example and apply it to nixos
It cannot find the file Image inside the root of the boot partition.
Indeed, I got confused and put both the Image and dtbs folder under /boot on the boot partition while they should be on root. After moving them there, it tries to load kernel but it fails with:

Looks good so far. Fat could be the issue, your rootfs is not as it should be. But now this will be nixos specific …
Right, I can add there something like:
fdt /path/to/dtb_file.dtb
but what bothers me the most is that my nixos kernel and the rest of the stuff that extlinux.conf refers to is on a different partition (extlinux.conf is on boot while rest is on rootfs)
When I tried to boot it the process failed with:
Found /boot/extlinux/extlinux.conf

Skipping nixos-default for failure retrieving kernel
EXTLINUX FAILED: continuing...
Which is somehow not a surprise. Could you tell me how can I refer to the rootfs partition in that file? Or maybe I could merge both boot and rootfs partitions and then I wouldn’t have that problem at all?
The entire purpose of the boot partition in fat is that the bootloader can access it, and the rootfs partition can be anything, not readable by bootloader
However, uboot can also read ext4, but I’m not sure if distro-boot reads from ext4.
You need to parted set boot on then also on the rootfs partition, formatted ext4. It will then hopefully search it also. I think it could find the /extlinux/extlinux.conf file on that partition too. But first remove it from boot partition before trying, as this will be searched earlier
Or you make nixos copy the files to the boot partition mounted at /boot
Finally some success

However it hangs here. The problem might be the one described here: https://nixos.wiki/wiki/NixOS_on_ARM#Enable_UART
If you try to use UART to log on NixOS, you might hang on the line “Starting kernel …”. To enable UART, you will need to add at the end of the line that contains
loglevel4in the file/extlinux/extlinux.confthe text:
/extlinux/extlinux.conf
console=ttyAMA0,115200n8
/extlinux/extlinux.conf

However I already have in my extlinux.conf this:

Can I bruteforce it and add S1,S2 and S3?
Perhapse someone at nixos can help you with the kernel.
Is it configured for the appropriate mediatek devices?
Edit: i found out that I cannot use the standard archlinuxarm linux kernel, because many mtk config options are not enabled. Mediatek boards are not included. It is why I need to use my own linux package.
It doesn’t apply any patching to code, only some changes to devicetree. Then I added Dynamic overlay support, which is an addition to the code. I use Dynamic overlay to access Emmc at hs200 when booting from sdmmc
Is it configured for the appropriate mediatek devices?
Not sure what do you mean by “configured”. I used latest version of unstable channel that contains the latest kernel and I can see dtb files for mediatek devices in the nixos image:

i found out that I cannot use the standard archlinuxarm linux kernel, because many mtk config options are not enabled. Mediatek boards are not included. It is why I need to use my own linux package.
Ah that might be it. What do you mean not enabled? How can I enable it? Also what do you mean “mediatek boards are not included”?
It doesn’t apply any patching to code, only some changes to devicetree. Then I added Dynamic overlay support, which is an addition to the code. I use Dynamic overlay to access Emmc at hs200 when booting from sdmmc
You mean that even though mediatek devices are in the devicetree, there are no patches applied to kernel? Sorry, I am not sure if I understand.
Anyway, I decided to try out the dtb file that you sent earlier. I modified the extlinux.conf and changed
FDTDIR ../nixos/wbv7qr9q5bqlr4dn5srjqmhxppp2sxgn-linux-6.3.1-dtbs
to
FDT ../dtbs/mt7986a-bananapi-bpi-r3-atf.dtb
And it worked (sort of):

The error obviously stems from the fact that I am not using partition layout from the original nixos image but rather my modification using atf etc. But that seems to be mostly concern of nixos configuration.
However, I wonder why it worked after switching to that file ? Could you explain what kind of changes have you made there comparing to the original file?
edit:
Have not tested this u-boot for applying overlays, so use this .dtb for now (sdmmc and compatible with direct atf->kernel boot): mt7986a-bananapi-bpi-r3-atf.dtb (23.8 KB)
Maybe that was the reason wdyt?
See def config of @frank-w
And/or mine:
https://aur.archlinux.org/cgit/aur.git/tree/defconfig?h=linux-bpir64-git
It selects which drivers are build into the kernel.
With a glance at your log looks like at least some mtk support build in.
The dtb I shared has overlays applied, so you can try that to start with, not worrying about overlays.
Just set label on your rootfs partition
@frank-w if that was only that easy tried that (keep in mind that I merged boot and rootfs partitions for the sake of testing):

PANIC at PC : 0x0000000000204bf8
I guess that @ericwoud’s atf requires u-boot partition to be called exactly bpir3-sdmmc-boot.
I will try to un-merge boot and rootfs partitions now.
edit: Although it also makes me wonder because the nixos installation disk does not have any labels assigned:
sudo parted /dev/loop1 19:02:09

How could that be?
The dtb I shared has overlays applied, so you can try that to start with, not worrying about overlays.
That was the result of trying it. The regular one doesn’t work which I think indicates that the u-boot I got from ftp doesn’t support overlays.
I think overlay would work as i have not changed config for it in u-boot. But it is more difficult to get it right and be able to boot. And I have not used it. Worry about it when you have booting ok.
The partlabel indeed needs to be exactly bpir3-sdmmc-boot. You can leave u-boot on boot partition, save all kernel files on rootfs partition. So keep 2 partitions separate. ATF cannot read ext4.
You can checkout partlabels with
lsblk -o name,partlabel
Edit:
But any normal os will have the ability to save extlinux.conf, initrd and Image Image to the boot partition mounted at /boot
Worry about it when you have booting ok.
good idea
You can checkout partlabels with
Yes, lsblk was the answer. parted only shows labels for gpt partition table while that was msdos partition table, then I had to use dosfslabel to change the label name. After that the system booted without any errors up to the point:

where it hung. I briefly looked looked that last line over the internet and it might indicate some problem with mounting rootfs. Maybe it tries to mount the same disk for the second time and fail?
Another reason to split them into boot and rootfs I might also try to increase log level in extlinux.conf
But any normal os will have the ability to save extlinux.conf, initrd and Image Image to the boot partition mounted at /boot
I actually thought about putting all of them in the rootfs. Is there any preference for one over the other?
Whatever works best for you.
Why do you choose for nixos? It is definitely more complicated in some aspects. I’ve chosen Archlinux because of the Rolling updates and the pkgbuild system
Afaik bl2 only looks for gpt partition fip to load uboot from and rootfs should be an ext2/3/4 or similar handling linux filesystem permissions…so not fat
