Mainline kernl for OrangePI 5 Max after upgrade to Trixie

[enx1998]

Hi all,
I update DietPi from Bookwarm to Trixie and I install vendor kernel. Is it possible to install mainline kernel?
How can I install it?

Thanks, ENx

[MichaIng]

sudo apt install linux-{image,dtb}-edge-rockchip64

Or here mainline Linux images: https://dietpi.com/downloads/images/DietPi_OrangePi5Max-ARMv8-Trixie_mainline.img.xz

Probably onboard WiFi does not work because of a missing driver.

Thank you very much @MichaIng,
I managed to install the edge mainline kernel, but I need zfs and I realised that the version currently available on Debian Trixie (2.3.2) requires kernel version 6.14 at most, so I cannot use the edge mainline kernel.
Is the current mainline kernel not compatible with OrangePi 5 max?

Ah right I remember that ZFS always lags behind support for latest Linux releases. Then an LTS kernel is needed. NPU driver will be missing and less VPU/GPU support, but no problem for a headless system:

sudo apt install linux-{image,dtb}-current-rockchip64

One hint: Be careful when uninstalling kernel packages, they tend to remove the /boot/dtb symlink to the versioned device tree directory. Hence after removing/purging a kernel package, even if a different one is still installed, verify that /boot/dtb points to the correct /boot/dtb-6.x.y-foo-bar directory, matching the Image and initrd.img symlinks. When installing a kernel package, however, all 3 symlinks are generated/updated correctly.
