Install latest mainline kernel on RPI3

[peracchi]

Long time away from my PIs…

Yesterday I prepared a SD card with manjaro-arm-installer and after boot used some saved commands to install latest mainline kernel.

Everything goes smooth but after reboot I noticed that I was still on installed kernel.

Commands used:

• remove actual kernel ( 5.15.67-0.1 )

sudo pacman --noconfirm -R linux-rpi4 linux-rpi4-headers

• install latest mainline kernel ( 5.19.3-1 )

sudo pacman --noconfirm --needed --quiet -S       \
  linux-rpi4-mainline linux-rpi4-mainline-headers \
  raspberrypi-bootloader raspberrypi-bootloader-x

What I missed?

You shouldn’t remove your currently running kernel.

If you just install linux-rp4-mainline it will ask if it should replace the normal kernel. Just say yes to this.

PS: Make sure that your boot partition is actually mounted on the system before doing this. There was a bug in the installer, that resulted in the /boot partition missing in fstab. This was fixed in version 1.5.1 of the manjaro-arm-installer script.

Hi @Strit !

How should I add the /boot partition to fstab? I mean, first time experimenting with f2fs, should I do something unusual at fstab?

Below some background info:

Yes. Add the boot partition to fstab, then you can update/install kernels.
