I have a old tv box that I dont want to throw away. It is a MXQ4k the board is a RK3229-BOX V4 with Nand flash. The problem is the when i flash a 4.15 focal image I get the Armbian Os working but when I flash the latest 6.13 I get "Gave up waiting for root file system device". The same hapens when I try to instal Librelec. My knowlege of Linux in general is limited and I am lost. Thanks in advance.
