Hi,
i have built the image for rpi4 using openembedded-core and meta-openembedded but i found that by default its taking the kernel which is linux-raspberrypi which is 4.19.x or 5.4.y but i want to change the kernel to the vanilla,5.5.6 from the mainline.
Can someone guide me on how i should proceed with ??

Hi Pankaj,

You can use the linux-stable recipes in meta-kernel
(https://gitlab.com/openembedded/community/meta-kernel) to achieve
this. We don't have recipes for 5.5.y as it's already EOL but there
are recipes for 5.6.y. I'll be adding the recipe for 5.7.y very soon.
There will likely be a little integration work to do to get this
working with a Raspberry Pi, I've already done that for raspberrypi3
(as you can see in the readme for the meta-kernel layer) but other
models are currently left as an exercise for the reader. Patches are
welcome :)

You could also look at the linux-yocto recipes in openembedded-core.

Thanks,

Thanks for response..You have provided the link ,But i want to build specifically for 5.4.3 only ,where i should change in the existing file so that i will be able to build the image for same since i am very new to yocto can you help me out ??

Why do you want to use an old patch release in the 5.4 series? You
should be using the latest patch release in a stable series so that
you've got all the bug and security fixes.

Thanks,
