Where to find and how to flash Linux on a tv smart box?

Question

linux

There is such a player on android. I don't have a monitor to hook it up and set it up somehow. Is there any way to reflash this prefix to some kind of ubuntu in order to connect via ssh and not use the monitor at all (raise some kind of ftp there, for example)? If necessary, I can solder to the uart and set up / run something through the adapter, just tell me what and where. Suddenly someone was doing something like this.
Allwinner a20 processor, there are two usb and a slot for an sd card

Answer 1

Try with Debian following this instruction https://github.com/ssvb/sunxi-bootsetup/releases/t...
Without a monitor, you can display the console via uart.
Or something from this linux-sunxi.org/Bootable_OS_images

Theoretically, you can roll armbian for a board with the same SoC. If there is a slot for a memory card, then fill it up and try to turn it on with the card inserted, maybe it will boot from it.
