I'm trying to install LibreElec on FriendlyARM NanoPi M4 RK3399 but I'm not seeing anything boot. When powering the device nothing happens - no LEDs, no HDMI output. I used the official release from https://releases.libreelec.tv/LibreELEC-RK33…anopi-m4.img.gz ( I went a couple of releases back as well -no change). via LibreElec USB Creator.
I am certain that the device is functional - it was running Armbian just before and I've also successfully installed DietPi. Help is appreciated! Thanks in advance
