I have a Raspberry Pi 3 Model B +. I want to install Screenly-OSE-. I have a problem with the image. I use the Zip image.https://github.com/Screenly/screenly-os ... SE_4GB.zip. I formatted my 16 GB card. The image is written with Etcher (Win 10 Version) on the card.
Unfortunately, the red LED flashes red for a very short time. The green SMD LED flashes briefly. On the HDMI connection is only a color pattern to see. My LAN connection is not recognized. The Raspberry is not in my existing network. What am I doing wrong. The Raspberry is usable with operating system from https://www.raspberrypi.org/. The LAN socket is recognized and I can control my Raspberry with Putty. I probably did something wrong with the Screenly Image. I can not make SSH settings. What can I do. I'm happy about the help. Thank you.
