@Maurizio Finesso Try editing on a linux machine instead of windows. I've seen some windows machines not be able to read the boot partition

Moved to the correct sub-forum

Please open the case and post images of your board so we can see what Ethernet chip you have.

In this case ethernet chip is realtek so it should be supported by armbian kernel? So problem is to find or make a modern DTS for this board?

Hi I'm trying to load the bookworm version on an amlogic S905X tv box that was working pretty fine with the bullseye version. What I'm not able to do is to have the boot partition where I can edit on SD Card. This happens with every of the compressed image file that are available for Amlogic tvbox. Probably I'm doing something wrong but after that I load the compressed file on SD card using Balena Etcher I don't find the boot partition readable in Windows. I'm using same procedure with older image (armbian 20.10 bullseye) that works fine. Please, help me to understand how to create it correctly. I have already look into docs but I don't find a solution.
