Thank you @Hqnicolas, 4g32g img did not work for me. I had no debug tool, so I don't know what're the blockers. But I tried to install retroarch in armbian, and load the cores from https://github.com/christianhaitian/retroarch-cores, it works for me.

Thanks for your great works on building armbian on this tv box. I'm also looking for a method where the box could start from usb, some systems like emmuELEC needs to be started from usb... I tried a lot but all failed, I'm a pretty fresh here. I had some stupid questions: 1. Does it support to change boot priority by Uboot? I tried rk Uboot and mainline Uboot, nothing of UBoot info was printed on the hdmi output. The dts file is decompiled from dtb file in one official armbian image. 2. How to flash and boot usb from UEFI?
