Hepl ! How to use rkbin-master
"
"Installation (without SD card, board with eMMC):
If you have no sd card slot and your board has an eMMC, you can burn the armbian image directly on the internal eMMC using rkdeveloptool and a male-to-male USB cable:
Download your preferred Armbian image from Armbian download page and decompress it.
Download the rk322x bootloader: rk322x_loader_v1.10.256.bin
Download a copy of rkdeveloptool: a compiled binary is available in the official rockchip-linux rkbin github repository.
Unplug the power cord from the tv box
Plug an end of an USB Male-to-male cable into the OTG port (normally it is the lone USB port on the same side of the Ethernet, HDMI, analog AV connectors) while pressing the reset microbutton with a toothpick. You can find the reset microbutton in a hole in the back of the box, but sometimes it is hidden into the AV analog jack
Plug the other end of the USB Male-to-male cable into an USB port of your computer
If everything went well, run lsusb: you should see a device with ID 2207:320b
Run sudo rkdeveloptool rd 3 (if this fails don't worry and proceed to next step)
Run sudo rkdeveloptool db rk322x_loader_v1.10.256.bin
Run sudo rkdeveloptool wl 0x0 image.img (change image.img this with the real Armbian image filename)
Unplug the power cord
Done!"...............
