I used BalenaEtcher to Flash Both images below.
U-Boot to SD-Card at https://yadi.sk/d/_rQgn_FosYuW0g/U-BOOT/U-BOOT-ARMBIAN/20201004

It seems I cannot boot when I have the USB stick with the SD card in the box, so I put in the SD card, hold down the reset button and then plugged in the power in the box, waited 30 secdonds, nothing happened, then I released the button and Linux system started to do a lot of stuff.
I will try to do the same again and when Linux system do its stuff I plug in the USB quickly to see what happens.
Can I put Both the Uboot and Armbian Image on the SD Card and if that works, what shall I change in any setting file if so?
I apologise for all these questions, I have read through a lot of forums and I am so close now (I think)!
Thanks in Advance!
