Fedora 35 Workstation

[MastaG]

Hi, I finally got my Odroid N2 back which was sitting in Morocco for over a year due to all the covid-19 madness.
So I've created a very clean Fedora 35 image.

Unlike my XU4 image this doesn't come with any custom software such as chromium, kodi or retroarch.
I'll first finish my F35 image for the XU4 before I'll build these for the N2.

Features:
- Kernel 5.11 from tobetter's repository
- tobetter's alsa configuration file
- /usr/local/sbin/gen-uinitrd for re-generating the uInitrd image

Audio and video are working fine.
Furthermore Fedora uses very up to date packages for mesa, so Panfrost seems to work out of the box.

Upon first boot you'll be greeted with the initial setup for setting up your user account.

Enjoy!

Nice to see you back in action.

Hi MastaG,

thank you! Do you by any chance have a documentation on who to create the image myself?

Yours,

I see that you tricked the distro into using /media/boot not /boot. What steps do I take to upgrade the 5.11 to 5.16 kernel?
BTW for others this has Gnome 41 installed. It's not a headless basic version which is fine by me.

[MastaG]

@trwn2p
It's the official Fedora Workstation image for aarch64.
So everything comes from the official repositories.
If you would like to have a headless version, you can try and patch the Fedora Server image instead.

Regarding the kernel, I guess you'll have to build it yourself.
Try to look at GitHub pages from various members such as tobetter, memeka, areascout etc..
I usually just clone and build their Linux repositories lol.

@MastaG

Would you mind creating a short guide on how to do this? I really want to try fedora but have never worked with Linux before (meaning haven't built my own kernel or u boot)

[wallyz21]

I couldn't get this one to boot:

Download: https://oph.mdrjr.net/MastaG/F35-Odroid_N2.img.xz

or the official download from the Fedora site to boot on an N2+

https://alt.fedoraproject.org/alt/

Tried both settings on the SPI switch!

[trwn2p]

I decided to leave this alone since Masta isn't willing to maintain it with current kernel abilities. I'd suggest if ya want gnome to use the brand new Ubu 22.04. See the new thread in How-to's.

[wallyz21]

Looking at the Fedora support for ARM Wiki page :

https://fedoraproject.org/wiki/Architectures/ARM

Amlogic is not one of the supported devices. Which means Odroid N2(+), Khadas Vim3 or Beelink!

Did you manage to get MastaG's image to boot?

I had no luck!

Do you have an N2 or N2+?

[trwn2p]

It booted on my N2+ using sdcard and switch set to emmc iirc.

[eruo1]

Yes, it does boot up. But, not with petitboot.

[wallyz21]

Ok. So I managed to get MastaG's image to boot.

The kernel is at 5.11. Which has no kernel header packages from fedora. So can't add dkms modules. I noticed after the upgrade there was a 5.16 kernel in /boot but the N2(+) is using using /media/boot instead. Not really sure what to play around with here to update the kernel to the latest!

I've not played with this image yet, so not have many ideas.

What do you have with cat /etc/fstab and uname -a?

If your boot script /boot/boot.scr read /boot/vmlinuz-*, I think you can ignore /media/boot and remove the line in /etc/fstab. I guess /media/boot is from Hardkernel's root file system. Please check /boot/boot.scr which kernel is loaded.

[wallyz21]

There is no boot.scr in /boot or anywhere on the system.

[wallyz21]

Looking in /boot there is :
-rw-r--r--. 1 root root 26970597 Nov 11 16:59 uInitrd-5.11.18-n2+
Which has the same hash as the one in /media/boot :
-rwx------. 1 root root 26970597 Nov 11 04:59 uInitrd
But there is no match for the Image in /media/boot
So I'm not sure if that should be :
-rw-------. 1 root root 26970533 Nov 11 16:59 initramfs-5.11.18-n2+.img

Any thoughts?

Any thoughts?

Can you check the directory /boot/grub2 or /boot/efi if there is a file that points to 5.11 kernel?

[wallyz21]

I should mention the boot mode is not spi. So where is uboot hardwired to look for the boot.ini? I think it looks for a vfat partition.

I might try booting from spi and test what happens.

[wallyz21]

So to my surprise it is now booting in SPI (petit boot) mode as well but still choosing kernel 5.11 and not the latest.

There are /boot/grub2 & /boot/efi directories which have contents.

I am running grub2-customizer and saving a configuration to see what happens!!!

[wallyz21]

After configuring grub2 to boot 5.16 the system starts the boot but then fails.

I can see in the petit log that it is reading the grub.cfg from /boot/grub2/grub.cfg.

So I have to assume at this moment that the standard Fedora Work Station F35 images are not N2+ compatible.

The 5.11 N2+ kernel doesn't seem to be shown by the grub-customizer so that is probably an addition my MastaG.

I can still force a boot by using NON SPI mode so all good still.

[acongdon]

Upgraded to Fedora 36 with no issues but still running 5.11.18-n2+
Would love to hear a procedure from anyone who has updated the kernel successfully.

[MastaG]

Sorry for the lack of answers my friends.

As I did most of my engineering on my XU4, I didn't know the N2 platform very well, so I used the legacy boot method instead of petitboot.

My N2 currently serves as a Android TV box (thanks to Voodik's excellent work) in Morroco.
I'll replace it with a N2+ (a little extra juice for RetroArch etc) soon.

This will free up my N2 so I can create a nice and clean Fedora 36 image, this time with petitboot and a more recent kernel (including the headers/sources).

But it will take a couple of months.

[chris_ca]

Hi. Anyone know where there might be instructions to boot into Fedora 37 on ODROID-HC4 via SD card?
I've tried (for almost a week) using the wikis to build u-boot and try to boot from petitboot, but something seems to be missing.
If I just start the HC4, it goes to the petitboot menu and though that recognizes there's a boot partition on the SD card but won't boot from it. Pressing the boot switch results in a blank screen, and honestly I'm not sure exactly what the "boot switch" is supposed to do - seems like it should attempt boot from the first bootable partition?

Seems like it's possible to get Fedora running on the HC4, but all instructions so far seem to be incomplete.
Any guidance would be appreciated.
