But still
1.display port switched off after booting
2.build in ethernet isn't working and usb2 ports isn't working
-
When I add more stuff to device tree it started to run on full speed
It is 2.5x faster then rock 5
-
I was able to boot
with this branch
https://github.com/jhovold/linux/tree/wip/sc8280xp-v6.2-rc8
and with microsoft dev kit patches on top of that
https://github.com/shawnguo2/linux/commits/devkit-dt-6.2-rc5
and this kernel command line
clk_ignore_unused efi=novamap earlycon=efifb console=efifb
build in ethernet don't work as not all usb-c ports are active
so you will need to connect usb-c ethernet to usb-c ports on the side
for speed
Cpufreq-info show 3GHz but device is running as on lowest freq(800MHz) as that is my experience with running benchmarks

Some UEFI is able to start only signed GRUB/KERNEL
Are there any support this this?
I found that for that purpose suse has some signed shim

Surface pro X is same hw as windows dev box 2023

@balbes150 Can you explain how UEFI is working on arm?
Is it passing some dts or how the linux kernel know what drivers should it start ?

UEFI can be way how to boot it maybe

As ubuntu 22.04 has realy up to date compiler. Is it possible to force armbian to use local copiler? linaro gcc compiler is 8.x but gcc in ubuntu 22.04 is 11.x.
Is it possible to force armbian to use local compilers?
Or can armbian update gcc to 11. x ??

Because we are downloading one package from there.
https://github.com/armbian/build/pull/1982And is it safe to mix ubuntu and debian repos?
-
Why armbian put debian.list to ubuntu package list (/etc/apt/sources.list/debian.list)?
I am on ubuntu so I don't understand why should I have mix of debian and ubuntu packages

work from The-Going is only for source package
-
I mount this one on Hikey970
I can only recommend!
-
I just try 5.7rc1 build of linux kernel for odroid c2
And armbian can't create linux kernel package
It looks like some problem in https://github.com/armbian/build/blob/master/patch/misc/general-packaging-5.6.y.patch

I can take a look, but did you use armbian with some hand-compiled things or another image of sort?
PURE ARMBIAN
sudo BETA=yes EXPERT=yes ./compile.sh
and choose your RK3288 board
and as OS choose ubuntu 20.04
and then server
and then instal gnome
apt install ubuntu-desktop
everything should run out of the box
for the first time we should have working ubuntu gnome with gpu accleration on many boards
lima and panfrost is working JUST fine

Are you monitoring the voltage of your board? What board do you use?
How about other clocks like 500MHz?
What kernel are you using? Good luck.My board is some HDMI dongle like device with RK3288
but is is powered from micro usb
Kernel version: 5.5.11
I didn't modify kernel dts files
so I didn't add 500Mhz
-
I am testing RK3288 with ubuntu 20.04 (gnome) btw NICE
And I have some problems with panfrost and I am looking for anybody with RK3288 device that can confirm or not same behavior.
Problem is that when I switch GPU to 600MHz
sudo bash -c 'echo "userspace" > /sys/class/drm/card1/device/devfreq/ffa30000.gpu/governor'
sudo bash -c 'echo "600000000" > /sys/class/drm/card1/device/devfreq/ffa30000.gpu/userspace/set_freq'
and when I run glmark2-es2 or glmark2-es2-wayland
I start to see https://pastebin.com/NuYqHdxH in kernel.log
So I made bugreport(https://gitlab.freedesktop.org/mesa/mesa/-/issues/2693) for panfrost and they think that problem is in low voltage on gpu
as everything is fine on 400MHz
So anybody can try?
just build ubuntu 20.04 for your RK3288 device
sudo BETA=yes EXPERT=yes ./compile.sh
server build should be fine
and then apt install ubuntu-desktop
ubuntu 20.04 has almost latest mesa so everything work just fine

Where do you think they came from and why are not yet in the mainline?
It seems nothing out of advanced functions really works atm.
But at least we are now attached to the mainline + patches.Which needs maintenance attention if we want to move on faster..mainline rules All amlogic boards are also on mainline
mainline u-boot will be also fine. it should work I think
so some users can try lima drivers on odroid c2
and if anybody want arm opengl es drivers on odroid n2
And as always mainline kernel has better stability.
Btw what about passing coherent_pool=4M to kernel. Any plan to add it? I saw your post

Wasted 10+ h and I am not satisfied with the outcome - multimedia features are not working, something is still missing. But N2 seems stable - rebuilding images and enabling nightly images at master branch (5.5.>) https://github.com/armbian/build/pull/1748why?
multimedia like HDMI audio or video decoding or what?
good source of kernel patches are here
https://github.com/superna9999/meta-meson/
or khadas
https://github.com/khadas/fenix/tree/master/packages/linux-mainline/patches/5.5-rc2
-
Are there any reason @Igor why armbian use @balbes150 's repo for kernel?
for current and dev
As I hope that N2 or g12b has pretty nice support with mainline kernel and u-boot
armbian use mainline for g12b so what was the reason for this change.
I really like idea what armbian use for some other boards odroid c2 for example
mainline kernel + patch-set

all usb ports working
cpufreq don't
