I downloaded image from here:

and the official sites says it is 5.10 kernelDebian Buster Desktop (Linux 5.10),
but when i mounted this raw image, the kernel header is 4.4.194.
And where to download the real debian image with 5.10 kernel?

You can skip that and move to Rockpi 4 - Armbian

As the official image it is so “weird”…armbian is a good choice, thanks…
