rock64 how set hdmi hotplug

  • Hello !

    I try to find a way to set hdmi hotplug on my rock64 AND to force a specific resolution to the rock64 also.

    I want to install my rock64 in my camping car, when I plug the power on my camping car, tv power on and the rock64 power on also but it finish to boot before the television. Each time I have to turn off the rock64 and restart it. What I want is that the rock64 boot at a specific resolution even if the HDMI is not plugged.

    On a Raspberry pi it's easy to do, there is a way to do that on a rock64 ?

    Thank you !
