I have issue with using v88 mars android box with Armbian Focal xfce kernel 4.4.194 (legacy). Installation to nand with multitool every time progress and finish without problem. Also rk322x-config and armbian-config progress without problem. But when I start apt-get upgrade after successful apt-get update system crashes from X to terminal with many kernel messages (see image). Power adapter is original 5V 2A. I reinstalled system few times and it was always without problem. sudo rk322x-config su
