I have a problem with the proper launch of Waveshare 7 LCD HDMI (C). I use Armbian in the latest version. The display is detected only after the system has been fully started. Then I can connect the display and fully use it. At the start of Nanopi, nothing appears on the display. I have to unplug HDMI and USB power each time and reconnect after booting the system. I think it's the drivers' fault in u-boot. How to fix it?
I apologize for my poor English.
