Hello there, I’m new with Rock PI. Unfortunately, I’m unable to see it booting. Tried Debian, Ubuntu and Armbian image done with BalenaEtcher (also tried by decompress image before flashing). No more luck with eMMC module. The only thing working is that my laptop detect something when OTG connected. Any suggestions? 
Rock PI 4C+ nothing display. Only solid green led
You have serial console? That would perhaps tell something, but if nothing works … this is not a good sign. You tried right images? https://imola.armbian.com/dl/rockpi-4cplus/
@igorp You’re right, wrong image.

Must connect display to the 2k HDMI port (next to USB-C). Now it’s working.
