Hello @Marcio Melo,
I'm installing Armbian on Rockchip, Amlogic and AllWinner-powered TV boxes for usage in public schools in Brazil. The Rockchip and Amlogic TV boxes were (relatively) easy to install Armbian, but, as far as I know, Allwinner SoCs are not supported by Armbian and we need to do the heavy lifting to install it on these TV boxes. However, I can't find any tutorial do this. Can you tell us how did you managed to install Armbian on your TV box?
Thank you.
PS: I'm trying to install it on a RedOne TV box powered by an ik316 SoC.
