I have assembled a fully working image for RockChip 322x (quad core armv7/32bit) tv-boxes:
These are cheap-*ss devices that usually get dumped into the trashcan, because they have an ancient Android onboard, and they rarely work well.
After many days and the help of the wonderful people at the Armbian board, I managed to assemble a fully working OpenWRT 22.03-rc6 with Kernel 5.16.11.
The filesystem is based on rpi2/model b (armv7-neon), it has a different kernel, full moduleset, and a lot of hardware optimizations.
Cheap and useless as they are, these boards are quite fast as routers, and thanks to OpenWRT now you can have a nice interface and a wealth of software to use!
Download MULTITOOL image and burn it into an SD card, follow instructions for its use here:
Get the OpenWRT image here:
Put it into the SD card (images dir) and flash it!
Follow instructions here:
The box will answer to 192.168.1.1 on its ethernet 10/100 port.
It has an internal wifi, but rarely works and it's disabled by default.
Since those boxes have only one interface, they act like a raspberry 2.
