Hello, just received my Raspberry Pi 4 model B today. Attempted to set up Octoprint. Setup was very simple, loaded the raspberry pi imager and flashed octoprint right from there, properly edited files to enable network connections. However, when I insert my micro SD (bought straight from sandisk) and turn the Pi on, I get 4 slow and 4 rapid green light flashes. Reading around for support and it sounds like an SDRAM error. Is this fixable?
I have also tried loading other systems, such as retropi, with no success.
