GT King Pro-Ubuntu 21.10 Impish Indri Firmware with Panfrost-5.14.15 Kernel

Hi @darkstar,

Not sure this will interest you.

FYI, the kernel-5.15.33 by @ophub and/or @unifreq https://github.com/ophub/kernel/tree/main/pub/stable does not require the chainloader u-boot.ext to boot on GT King Pro.

Hi JFL,

Did you try it on my impish firmware?

Hi @darkstar,

I have only tried it on @ophub firmware (Jammy) with kernel-5.15.34-flippy-71+o. Installed on a USB and it works. It can boot without u-boot.ext and it can boot from any of the USB 3.0 Port or on USB OTG port. It reboot and shutdown normally. It uses uInitrd and zImage. https://github.com/ophub/amlogic-s9xxx-armbian/issues/236. Different from Manjaro-Arm method.
Kernel-5.15.34-flipply-71+o can also boot with the chainloader u-boot.ext on USB OTG Port only just like what we are used to.

The kernel package is very different from the usual linux-image-xxx-xxx.deb format that I know. For example 5.15.34.tar.gz , it have the following files:

boot-5.15.33-flippy-71+.tar.gz
dtb-amlogic-5.15.34-flippy-71+o.tar.gz
header-5.15.34-flippy-71+o.tar.gz
modules-5.15.34-flippy-71+o.tar.gz

It is not in the format that I am familiar with how to install on your impish firmware or on Khadas-Vim3-Gnome-Focal firmware.
Edit:
Hi @darkstar,

To update the @ophub kernel the command is:

sudo armbian-update 5.15.34

"armbian-update" is a bash script located in /usr/sbin

"armbian-update" bash script can be found here:

https://github.com/ophub/amlogic ... sbin/armbian-update

Question: if I copy this armbian-update bash script to /usr/sbin on another linux firmware (example khadas-vim3-gnome-focal) it will be able to install ophub kernel?

Hi @darkstar,

Update on ophub kernel-5.15.34-flippy-71+o. it should also work on your Impish firmware.

Installed this kernel on http://dl.khadas.com/Firmware/VIM3/Ubuntu/SD_USB/VIM3_Ubuntu-gnome-focal_Linux-5.16-rc2_arm64_SD-USB_V1.0.10-220108.img.xz firmware and it boot up without u-boot.ext.

First copy armbian-update bash script to /usr/sbin
and copy ophub-release to /etc folder without this file "armbian-update" will not proceed. Can manually create one to trick the bash script:
I actually copy from ophub Jammy firmware and edit it to reflect "focal" and Kernel_Version='5.16-rc2'
cat /etc/ophub-release
VERSION_CODEID='ubuntu'
VERSION_CODENAME='focal'
FDTFILE='meson-g12b-gtking-pro.dtb'
UBOOT_OVERLOAD='u-boot-gtkingpro-rev-a.bin'
MAINLINE_UBOOT='/usr/lib/u-boot/'
ANDROID_UBOOT='/usr/lib/u-boot/'
SOC='s922x-reva'
PACKAGED_DATE='2022-04-03'
KERNEL_VERSION='5.16-rc2'
K510='1'
After "sudo armbian-update 5.15.34"

khadas@Khadas:~$ cat /etc/ophub-release
VERSION_CODEID='ubuntu'
VERSION_CODENAME='focal'
FDTFILE='meson-g12b-gtking-pro.dtb'
UBOOT_OVERLOAD='u-boot-gtkingpro-rev-a.bin'
MAINLINE_UBOOT='/usr/lib/u-boot/'
ANDROID_UBOOT='/usr/lib/u-boot/'
SOC='s922x-reva'
PACKAGED_DATE='2022-04-03'
KERNEL_VERSION='5.15.34'
K510='1'

I think this file seems like second stage bootloader.

UBOOT_OVERLOAD='u-boot-gtkingpro-rev-a.bin'

Hi @darkstar,

Based on my experience, it does not use the second stage bootloader.  The initial boot up screen does NOT have the usual second stage boot loader verbose, the available RAM now show 3.26GB (just like Manjaro-Arm Bootscript) and you can boot up on any of the USB 3.0 Ports not only on USB OTG Port.

I rename the second stage bootloader to u-boot.ext-backup so it is NOT in use and it boot up.  If I switch back to linux-image-amlogic-mainline kernel I need the second stage bootloader u-boot.ext or lese it will NOT boot.

The ophub-release file is generated based on which image/firmware you use from ophub firmware.  I use gtkingpro-reva firmware.

From ophub:
At present, the kernel of 5.15 has a TEXT_OFFSET patch, which is the same as 5.4 and can be used without u-boot. The simple understanding is that it is the same as the previous 5.4.

you dont need to change anything, just follow instructşons on first post.

Thanks for the advice. Finally, I started the device. For now, I have two questions: 1 / How to extend the system partition because I have about 200mb of free space, even though the usb drive has 64gb? The output sound is not working or not active. The sound from the bluetooth device is there. 2 / How to activate the sound on hdmi? the adapter / audio output device is not visible.

You can use "gparted" or "disks" utility to increase the partition.

Thank you. Partition widened but no sound via HDMI. Can you advise something?

check your g12_sound.sh settings.  If looks like this then uncomment the OLD CONF and Comment Out NEW CONF :
