Debian/Ubuntu Netboot Installer (Feat. Ubuntu Gnome Desktop with Wayland)

[mikec]

OK, I'll try an older version. Petitboot had a black background with previous versions. I had a hard time flashing an older version though using spiboot.img on a flash drive at least. If I recall correctly I did not have visual feedback it was flashing, and I turned off power I think, and ended up with a corrupt spi (at least so I think). I'll try again though. Thanks.

[mad_ady]

Leave it for 10 minutes to finish flashing even if you don't have feedback...

[mikec]

I tried the 'update' method with the 2020-10-20 spiboot.img. When petitboot booted, it said that it's 'up-to-date'.
I then tried the 'recovery' method using http://ppa.linuxfactory.or.kr/images/pe ... 201020.img
It seemed to boot (flashing SYS led), but my monitor said that the timing was out of range, so there was nothing on screen. I waited until the SYS light stopped blinking, pulled the SD card, and the power. I replugged-in the eMMC, SD, switched the boot switch to SPI, and booted. The SYS light started blinking, nothing on screen again, but finally booted from the eMMC.

The petitboot.cfg on the recovery image has hdmimode=480p60hz, but this is only for the recovery image boot I presume. If so, how come booting from the now-recovered SPI (2010-10-20) doesn't show any video? What is the resolution set to there?
I'm going to change the petitiboot.cfg to 1080p60hz, and see if my monitor shows something. At lteast that would give information during SPI flashing.

Why are the newer versions not OK to use?

[mikec]

Commenting out the 480p60hz line and uncommenting the 1080p60hz one gives me 'no signal' on my monitor. The boot seems to go ahead though, since a display.bin and edid.bin are written to the SD's partition, and the spiboot.img is deleted (something I noticed also happened when I booted with the default 480p60hz).
Is it me, or are these petitboot images buggy?
Confusingly, the upgrade/update image has 'spiboot' in the image name, while the recovery one has 'spiupdate' in the name.
It also seems like petitboot won't downgrade using the spiboot.img, or did I do something wrong?

[mikec]

OK,
It seems like I maybe didn't let it finish flashing the first time. This time I waited longer, and the n2 rebooted into petitboot 2020-10-20, with a pink background. I pulled out the power, replugged-in the eMMC, switched the boot switch to SPI, and it booted petitboot 2020-10-20 again -- so it seems like the flash worked. The background is still pink though...
It is just my opinion, but https://wiki.odroid.com/odroid-n2/os_images/petitboot is somewhat confusing.
It doesn't say which version(s) should be downloaded, some links are to (ppa.)linuxfactory.or.kr, some are bit.ly links, the recovery image when flashed onto an SD and mounted from there doesn't have the same files as in the screenshot on that page, the instructions are at the bottom, not the top, etc. I hope you don't mind critical comments, and sorry for the off-topic, this should probably have gone in the petitboot thread.

A small status update.

I installed a prebuilt Groovy (20.10) server image from the linuxfactory to an SD card and loaded it up on the N2 (non-plus). Went fine.
Did an apt update and an apt dist-upgrade. Rebooted All fine.

Installed the kubuntu-desktop, went fine. Reboot.
Showed only two lines, one about panfrost and one about SElinux and a missing file.
Then nothing, no bootsplash or scrolling info text lines.
Nothing for a long while.

Then all of a sudden... Boom! SDDM, the login screen for KDE.
But then with a lot of distortion, ugly lines over the input field, missing letters, etc.
Login worked. Got to a desktop, with garbled mouse cursor, etc, etc, it is all not quite there yet.

But, Panfrost on the G52 and it atleast boots and loads an X11 desktop, well, sorta. Yes!!
Significant, working, measurable progress.

So, to whomever wants the N2 with KDE on Panfrost, not quite yet, but it now actually exists.

Are you sure you have installed panfrost?
I experienced the same thing once, afterwards I realized that I did not install Panrost.
sudo apt install linux-image-5.10.0-odroid-panfrost-arm64

If you installed Panforst, it may help to reinstall it.

Thanks! That made quite a difference.
It is still not completely smooth sailing, but user experience improved a lot.
And I verified with lsmod, panfrost the module is indeed loaded now.

[ Network management ]

Netwerk management is an issue though.
Anyone know how to fix it?
I have normal ethernet, never an issue.

But during boot I have to wait 2 minutes for the netwerk to fail to come up.
Then KDE seems to think I am not online, while I actually am.
Any idea how to smooth that wrinkle out?

No network manager setup, so have to find out how that all works. Hmm...
Also, no audio, strange enough. On KDE, you have to manually add the odroid-alsa package.

Language stuff on KDE is also different.
This largely applies
viewtopic.php?f=182&t=37109&p=316208&hi ... ks#p316208
But you have to install the language-selector-common package.

Update: new mesa packages from tobetter, seems to have improved KDE experience a lot.

[istanbulls]

There is a network problem with minimal installations with Netboot.
When you complete the installation of ubuntu-desktop with netboot, this is not a problem.
To fix this problem, I am using these commands.

Code: Select all

sudo nano /etc/netplan/50-cloud-init.yaml

Code: Select all

network:
  renderer: NetworkManager
  ethernets:
    eth0:
      dhcp4: true
  version: 2

Code: Select all

  sudo netplan apply

I use netboot to avoid language problems. This is how I handle my Language and Keyboard settings from scratch. Also, any root access belongs to me.

No sound, classic problem.

Code: Select all

sudo apt install --reinstall odroid-alsa

[wallyz21]

Tried to install panfrost with this command:

sudo apt install linux-image-5.10.0-odroid-panfrost-arm64

I can see the vmlinux in /boot is linked to the panfrost kernel

vmlinuz -> vmlinuz-5.10.0-odroid-panfrost-arm64

Which worked fine. Rebooted but lsmod doesn't show a panfrost module!

What else do I need to do?

[odroidn2user]

Been playing around with the Tobetter 20.10 server image, and added the Panfrost kernel and the Kubuntu Desktop.
There clearly are some remaining issues with the panfrost graphics driver in combination with KDE, but man... It is good!

Smooth video playing in VLC and MPV, smooth browsing with Firefox, audio jack clearly working, no green line, no pinky gray, a responsive desktop.
Even my Electron app is working pretty smoothly! Video in Firefox could be a little smoother, but...

The N2 is really starting to live up to its promises!!

(The image processing / sharpening thing also needs to be solved yet, still looks strange.)

I recommend that you also try it with Ubuntu-Gnome-Panfrost. I am sure you will like it more. This suggestion is valid if you don't have a special love for KDE.

Nice, Ubuntu Gnome Panfrost is a bit better than KDE Panfrost indeed!
Most of the blinking windows and stuff is gone.

OK, now... The compression / sharpening thing and... Night color.
Why doesn't any ARM box driver out there support the redshift / night color feature!?

Thanks, I just wanted to check the version if they go properly from the package server. Recently I am taking more time for Arm Mali Bifrost and Panfrost, I have seen that Panfrost is really mature...video decoing performance is a different story but looks good to use so now.

[odroidn2user]

Yeah, it works pretty good, Panfrost on Gnome. Surprisingly so. Animations could be a little smoother.

Video decoding is fully software based, from what I can determine.
But it seems to do 1080p just fine, on the cpu, on mpv.
Maybe fullscreen panning showing some tearing.
Yeah, tearing is a bit of a thing still. But it is early days.

And I just updated to the latest, and updated the post above with it.

[odroidn2user]

Well, been testing the tobetter 20.10 image, with Panfrost and Gnome, on the N2 as a daily home driver (for non-work related activities), and it works surprisingly well.

So, a huge congrats to all involved! And many, many thanks.

The N2 finally reached a state where it can serve as a daily driver for normal home activities.
And do so well, without the feeling of compromising on a normal modern desktop look and feel.

There are some remaining issues (image processing artifacts, some graphics driver bugs, some tearing, some network configuration issues) but it works.
You can do your normal daily activities and do it right and experience a responsive, modern desktop system while doing it.
Impressive work.

I created a setup tutorial for myself.
I printed this out because I don't remember any of them and I feel lost on the black screen with a few texts appearing.
Once Panfrost is installed, odroid-homecloud-display setup doesn't work so I added it to the top.
I added the alsa setup to avoid sound problems.

[joerg]

I started also with this. But I have not yet upgraded to 20.10. When I use with wayland, I have to reconnect the wireless mouse and keyboard dongle after login from screensaver.
BTW, I try to set it up for my daughter, so she can use it also for video conferencing. Her school uses Cisco Webex and Zoom. I was able to start a test session with Webex, with Chromium is working, with Firefox is not. And when I try to open a test session in Zoom it tries xdg-open, but nothing happens. I think it tries to open a binary, but there is no for arm.

[mad_ady]

Note that zoom should be able to run from browser. In the xdg-open page there should be a link in the bottom page that lets you connect with a browser.

I'm curious how the N2+ will handle 30 video streams at once. The H2 uses about 50% CPU with Google Classroom.

[20210219] 5.10.16 kernel is coming

It's been long time to update new kernel version, I've pushed 5.10 kernel branch to build queue and new kernel version will be available in a couple of hours, still ARM Mali Bifrost will be supported but Panfrost won't with Ubuntu 20.04 since 20.04 package repository becomes too complicated. At some point sooner than later, the default kernel will be switched to 5.11 that I am currently preparing to publish the package.

Interesting features:

• Device tree overlay will be supported - the device tree support is limited currently but will be added more like Hardkernel's stock 4.9 kernel and will use the same instruction to choose and apply the device tree overlay blobs.

• 3.5"/3.2" small LCD device can be supported - continue to the device tree support, 3.2"/3.5" LCD product from Hardkernel can run with mainline kernel finally, more detail instruction will come later.

• ARM Mali GPU can be overclocked to 1000MHz, currently the max freq is 800MHz - some users already had tried to overclock the GPU upto 1000MHz which is 200MHz more than max currently, you can run 1000MHz if you won the silicon lottery.

• 'linux-image-5.10.0-odroid-panfrost-arm64' kernel package' is deprecated - this is for Ubuntu 20.10 users only. Since several patches for the Panfrost drivers are merged to officialy Linux 5.10 repository the same package is no longer required, I've managed a couple of packages to prevent the driver conflict between 'Bifrost' and 'Panfrost'.

• And several updates...

How to update the new kernel version?

Code: Select all

$ sudo apt dist-upgrade

More detail will be added if required and 1-2 pages will be added to https://docs.linuxfactory.or.kr/

So, how do I force it to boot the odroid non-panfrost kernel?
I've done the above, it mentions that I already have the most recent 5.10.0-odroid-arm kernel.
I did a: sudo apt install --reinstall linux-image-5.10.0-odroid-arm64

That installed the kernel again, but a reboot keeps loading the older panfrost kernel...
(I am not using petitboot, due to incompatibility.)

I'm probably asking a complete noob question, sorry about that.

Can I edit the /boot/boot.scr file with some text editor, like vi or mcedit ?
It seems to direct to the panfrost kernel.

However there is some binary stuff around it.

I think you should remove the Panfrost.

Code: Select all

$ sudo apt purge linux-image-5.10.0-odroid-panfrost-arm64

I tried it too but it failed. I have to switch to the other OS on my SSD for it to generate the same error.

[tobetter]

Code: Select all

$ sudo apt update
$ sudo apt install linux-image-5.10.0-odroid-arm64

So, how do I force it to boot the odroid non-panfrost kernel?
I've done the above, it mentions that I already have the most recent 5.10.0-odroid-arm kernel.
I did a: sudo apt install --reinstall linux-image-5.10.0-odroid-arm64

That installed the kernel again, but a reboot keeps loading the older panfrost kernel...
(I am not using petitboot, due to incompatibility.)

I'm probably asking a complete noob question, sorry about that.

I could just perhaps purge the kernel that I am active running? That thought is a little scary?

It's not noob question, but my incomplete explains...

Two options,
1) run sudo flash-kernel --force 5.10.0-odroid-arm64 which will switch the default kernel to the latest version from linux-image-5.10.0-odroid-arm64.
2) run sudo apt purge linux-image-5.10.0-odroid-panfrost-arm64, this will remove the package and will switch to default kernel.

I recommend to go for option 1, so check if your kernel is switched and and remove the *-odroid-parnforst-arm64.

And the purge with:

Code: Select all

sudo apt purge linux-image-5.10.0-odroid-panfrost-arm64

Also worked, it seems to have cleaned up the panfrost stuff nicely (from /boot at least, that's where I looked) and it boots the odroid-arm64 kernel.
Excellent.

(I do notice that reboots don't work though, with both the panfrost and the non-panfrost specific kernel. Have to pull the power cord.)

Yeah, I did the purge thing, that worked as well. The 'dpkg --remove' command doesn't find anything to remove any further.
Excellent!

/me feeling good, running the brand spanking new 5.10.16! Not even a week old

[Bad_bt]

My Odroid N2 worked fine until the 18th, when I ran

Code: Select all

sudo apt update && sudo apt dist-upgrade

that, among other things, updated mali-bifrost-dkms. At the end of the update I got this error:

Code: Select all

Running

Code: Select all

sudo update-initramfs -u

also ended in this error.

This kept happening until the 19th when the kernel 5.10.16 came out, where the output properly ended at:

Code: Select all

Installing new boot.scr.

However, in both of these cases (the day before 5.10.16 got released, and after it got released), I was unable to boot using the 5.10 kernel - Petitboot recognizes Ubuntu 20.04.1, but it ends in black screen. Accessing Odroid via SSH also doesn't work. I managed to boot Odroid using the 5.9 kernel by editing the entry via Petitboot (replacing 5.10 with 5.9). Right now, I'm running 5.9 in Wayland with mali-bifrost-dkms 24.0+202102182345~focal without any issues, but I'm unable to get 5.10 working.

I ran:

Code: Select all

sudo rm -rf /lib/modules/$(uname -r)/updates/dkms/mali_kbase.ko
sudo apt install --reinstall mali-bifrost-dkms

and also (because $(uname -r) returns 5.9.0-odroid-arm64, which is not where the problem is):

Code: Select all

sudo rm -rf /lib/modules/5.10.0-odroid-arm64/updates/dkms/mali_kbase.ko

Code: Select all

sudo apt install linux-image-5.10.0-odroid-arm64

but 5.10 still boots to black screen.

Code: Select all

sudo update-initramfs -u -k 5.10.0-odroid-arm64

doesn't fix things, though it ends without errors.

Code: Select all

sudo update-initramfs -u -k all

doesn't work either, and it makes even 5.9 boot to black screen as well, so I had to restore backups to /boot/

I realize I may have misspoke when I said 5.10 boots to black screen - it doesn't exactly go to black screen, it's more that monitor doesn't receive any input from Odroid and turns off.
5.10 still won't boot as usual, but I had one freak occurence where it DID boot to black screen (monitor displayed black screen, it didn't turn off), SSH worked, Nextcloud server on my Odroid was working etc. But it was just one time. Every other time it behaved as before (monitor doesn't receive input and turns off, SSH doesn't work etc).

5.9 is now stuck at the boot dmesg messages, but SSH works and Nextcloud server works:

@Bad_bt, can you remove the file /etc/initramfs/post-update.d/zz-mali-bifrost and reinstall mali-bifrost-dkms? Back up the /boot/boot.scr before running these commands and reboot.

Code: Select all

Okay, so I ran the first 2 commands and rebooted, after which I could run 5.9 with Wayland. After running the 3rd command, 5.9 got stuck at boot messages but could be accessed via SSH. After again reinstalling mali-bifrost-dkms, I could again run 5.9 with Wayland.
5.10 still can't boot - monitor receives no signal from Odroid and can't access Odroid over SSH.

It might be completely unrelated, but I'll still mention it - about a week ago I followed some steps to turn off swap and set up zram instead:
https://haydenjames.io/raspberry-pi-per ... arameters/
https://unix.stackexchange.com/a/224348
Everything worked fine, booted and rebooted without issues. Then a few days later, issues started happening after updating.

This is the first time I've had serious issues with Odroid. In the past, if mali-bifrost driver didn't work, I still managed to boot in X11.

I checked the log but not found anything wrong, I guess you messed up something while installing and following up the instruction I gave you. You should better to install again to another memory card if it's 5.10 kernel problem or something else.
