I burned a xz compressed image of Armbian Focal onto a good SD card using BalenaEtcher as instructed on the Armbian website. I placed it into my NanoPC T4 - which currently boots from the eMMC, and held the boot button while powering on. It tried to boot - but it kept reporting there was no bootloader file and seemed to be trying to load something from the internet, not the SD card. If I dont press the boot button, it simply ignores the SD card and boots from eMMC. I reburned the SD card several times, and each time it verified fine. Does anyone know what I did wrong?

I spent all day trying to get Tight VNC to work, but I have one of two problems that kept popping up: 1. The screen would use be a black grey screen and the curser was an "x". Useless. 2. The screen seemed to work, but it was not the same screen that was on the NanoPC. That is, my aps where nor even there. I need to share the same user/desktop / not start up a new one. I never had these issues on my Ubuntu system, so I'm at a loss.

Is there a way to share my Armbian screen with another computer, like I can do early with Ubuntu? I have my Armbian machine in one room, and I need to be able to control whatever is running there from my other computer in a different room. I can do this easily with Ubuntu's screen share option. How can I do that with Armbian? Peter

I have a NanoPc T4 that I use to control an astronomical observatory. I successfully installed Focal on an SD card and it boots perfectly. But now I want to know how can I install Arabian onto the eMMC chip? I'm not a programmer, but can follow basic instructions. If this is possible, any help would be appreciated. Thanks!

I just saw this old post, but have a NanoPC T4 and want to use my ASI camera also at USB3 speeds. Has this issue been resolved?
