I had a quick go at it with the other version of multitool and it had the same outcome. I have no reason to doubt it is indeed a rk3228a because it can reproduce 4k h265 files without much of a hiccup. I actually have another board that has an rk3128, but judging from entries on this forum, I'll have a hard time flashing anything to it.

I've soldered pins to those pads and I don't think they're transmitting anything, the middle pin is GND and the other two are at 3.3V when on. The serial adapter doesn't return anything on putty either. I'm going to try the "experimental" multitool, I'm still a noob and have yet to figure out how to get the dtb or original firmware, I'll look into it. The wifi chip is a Rockchip RK915A. I've seen some videos where people connect a usb male-male cable and use it to communicate with the board, maybe I need to do the same?

This is the board, I'm not sure about where to connect the serial adapter as I don't see any obvious UART pins.

I've been trying to get armbian to work on a rk3228a tv box but after flashing multitools on a sd card with balena etcher I insert it into the slot and it just refuses to boot, the status led just stays red and nothing happens. What is going wrong?
