Based on your experience, it looks to me it is way more difficult to get Armbian for s9xxx to boot on GT King Pro compared to balbes150 Armbian image if you choose to use kernel >5.10.

The positive part is with kernel 5.4 it boot without the need for the chainloader u-boot.ext and should have the flexibility to boot from any USB Port on GT King Pro, I suppose.

And you found an alternative Android Firmware for GT King Pro.

Does Panfrost works on kernel 5.4?

I'm back with linux-image-current meson64 v21.8.4 installed from arm64 from @balbes
On the other hand, I cannot start https://oph.mdrjr.net/meveric/po ... 20-odroid_arm64.deb
what modification should be made in extlinux.conf to be able to start it ..
If I use "zImage" I start arm64 5.9.8 from balbes and if I put "image" I start on linux-image-current-meson64 ..?
Edit : How did you install this .deb and especially while being started under the image arm64 of balbes or under the image meson64 ?

Does Panfrost works on kernel 5.4?

I haven't really tested .. I can't say ..

If you are now on balbes and on linux-image-current-meson64 the extlinux.conf:

LABEL Armbian
LINUX /Image
INITRD /uInitrd

Copy the Code

Download meveric-kernel (if you are not compiling any modules yuo might need to install the linux-headers also).

I would suggest you make a copy of all the files related to linux-image-current-meson64 (uImage, uInitrd, Image, vmlinuz, etc) in the /boot partition. This will enable you to quickly switch back if meveric-kernel gives you issue by just renaming these files to their original name or you want to switch between meveric-kernel and meson64 kernel easily.

Then install the with dpkg -i meveric-kernel. This will generate new uIntrd, initrd.img-xxxx, vmlinuz-xxxx. Note, if not mistaken the meveric-kernel does NOT create a new Image (which is the same as vmlinuz).

I think you might have miss this part. Copy the new vmlinuz-5.15.10-arm64 to Image. This should boot.

Linux arm-64 5.15.10-arm64 #odroid SMP PREEMPT Mon Dec 20 03:43:12 CET 2021 aarch64 GNU/Linux

Copy the Code

It might be good idea to "HOLD" linux-image-current-meson64 to prevent it accidently upgrade to current-meson64 v21.08.6.

Edit: You should also use the meson-g12b-gtking-pro.dtb for linux kernel 5.15. It can be found on /lib/linux-image-5.15.10-arm64/amlogic.

Noticed Armbian now have new kernel build like linux-image-edge-arm64 https://imola.armbian.com/apt/pool/main/l/linux-5.15.10-arm64). Wonder if it is the generic kernel for all the arm64 devices like what balbes did in 2020.

Nice, thanks for pointing me this mistake, I rename vmliunuz-5.15.10-arm64 as mImage and edit extlinux.conf for

LINUX /mImage

Copy the Code

so i can start easily by modifying this line in extlinux.conf
LINUX /zImage start kernel 5.8.9 from Balbes
LINUX /Image start linux-image-current-meson64
LINUX /mImage start meveric kernel 5.15.10
Really nice, uInitrd from meveric can start all this "image"..
Thanks for pointing to the right dtb
And really happy about this new armbian kernel linux-image-edge-arm64, have you tested ?
I'm leaving for Christmas for a few days.
I could not do a test at the moment but it looks promising.
Have a good day..

How can I do this cause when I use armbian-config for freeze system, just freeze linux-image-current-arm64 and linux-u-boot-arm64-current ..?

No, I have not tried the new linux-image-edge-arm64, not really sure whether it works with our device. If you test the new kernel linux-image-edge-arm64 let us know whether it works.

Glad that you found a way to switch kernel easily.

Not sure whether armbian-config will work with balbes image. You can also use "sudo aptitude hold linux-image-current-meson64".

Merry Christmas.

Today I tried ophub's 5.4 and 5.10 mainline firmware's, his second stage build "u-boot.ext" for each device works good without problem.
I will use it on my builds, it really seems good enough to run mainline kernel from sd card.

thank you guys for the information.

Hi @darkstar,
Merry Christmas and Happy New Year.

Interesting you managed to boot up ophub's with 5.10 mainline firmware on your GT King Pro. Were you facing the same issue of having of having kernel panic during booting process like what @gtkingpro.ac2n encountered? My GT King Pro is Rev A - similar to @gtkingpro.ac2n.

I will use it on my builds, it really seems good enough to run mainline kernel from sd card.

Good. You found a solution to build images that boot up on SD Card and USB Flash. Looking forward to your new builds.

Hi @darkstar,
Merry Christmas and Happy New Year.

At first boot kernel panic occurred, after second boot it was normal.
I installed xfce desktop and everything was good.
By the way I tried all with sd card, it seems promising.

Good to know ophub's firmware can boot quite reliably on GT King Pro with kernel >5.10.

Wondered whether ophub's kenerl 5.4.y supports Panfrost/GPU Acceleration on GT King Pro as it can boot without the chainloader u-boot.ext. Is there an advantage without the chainloader u-boot.ext?
