Building Linux Kernel with firmware built-in - TREEYA360

Hi, I appreciate the information is there a step by step for how to use the prebuilt kernel?

Here is what I tried with no success on Elementary OS 8 (it’s ubuntu based but maybe this could be a cause?):

I downloaded the stoney-kernel artifcat from the repo

Extracted the files and then preformed the following in the terminal:

sudo mv vmlinuz-6.13.7-chrultrabook-stoney /boot

sudo mv 6.13.7-chrultrabook-stoney/ /usr/lib/modules

sudo kernel-install add 6.13.7-chrultrabook-stoney /boot/vmlinuz-6.13.7-chrultrabook-stoney

/boot/initrd.img-6.13.7-chrultrabook-stoney does not exist, not installing an initrd

sudo update-initramfs -c -k 6.13.7-chrultrabook-stoney

sudo kernel-install add 6.13.7-chrultrabook-stoney /boot/vmlinuz-6.13.7-chrultrabook-stoney

sudo update-grub

I used this post to guide me as I did not know how to use the prebuilt kernels.

I then used guides to get the grub menu to come up so I could select the kernel but that wasn’t working for me so I changed the grub default boot by changing the grub file in /etc/default to the following:

GRUB_DEFAULT='elementary OS 8, with Linux 6.13.7-chultrabook-stoney'

I grabbed the menu item ‘elementary OS 8, with Linux 6.13.7-chultrabook-stoney’ from the grub.cfg item in /boot/grub.

and then running

sudo update-grub

Again and rebooted.

Upon reboot I confirmed it was booting into the kernel using

uname -mrs

I got the following output

Linux 6.13.7-chrultrabook-stoney x86_64

From my understanding it seems to be using the prebuilt kernel

However I have no audio on my chromebook so I am not sure if I am doing the steps wrong, any advice is appreciated.
