I bought this TV set-top box the other day in order to install armbian and install klipper for a 3d printer, however, my board is a little different from others and when I try to flash through multitool, the red indicator lights up and flashes yellow, I bought a set-top box with 1 GB of ram because this is enough for a Klipper (RK3228a, 1gb ram, 8gb memory), I hope very much for your help!
