I want to install NetBSD on PINE64 RockPro64. I flashed arm aarch64 netbsd image on my flash drive, plugged it into my RockPro64, also plugged monitor via HDMI-VGA adapter and keyboard via usb port. I powered my board on and... Nothing happend. Not even boot agent showed up on the monitor.
I'm assuming there is a problem with the HDMI-VGA adapter. So I have two options: make NetBSD work with the adapter or do a headless installation.
Unfortunately, I have never used NetBSD before, so I don't know how to do it. I have some experience with Linux, however.
