Hello everyone, I am a new Armbian user and don't have much experience with installing Armbian (both hardware and software operations). I have an old TVBox with an RK3399 chip as shown in the attached picture. Although I have spent time searching the Internet about installing Armbian on this hardware, all my efforts have come to a dead end. So I ask for help from you to install Armbian on this hardware of mine. Thank you very much. Wishing you a Merry Christmas.
