Want to boot linux in this old tv box

Incomplete hardware info. Open the housing, make a hi-res photo, and post it, so users could read the chip labels.

It's probably an Allwinner H3 device, so moved to that subforum.

You mean USB boot on an Android TV box? I doubt the boot loader will support that. Can't you use a TFF card?

You could try the OrangePiPC Debian image. I find the 6.18 kernel works well on my H3 OrangePiPC. https://armbian.com/boards/orangepipc
