I have a Raspberry Pi 4 (8GB) loaded with the latest arm64 testing image. Everything has been stable so far. When looking in Cockpit, I noticed that the system is reporting 2.8GB of total system memory. Running ‘free -m’ via ssh reports the same.
I’ve confirmed that the image loaded is 64-bit. Is there something I need to do to make the full 8GB (or 7.XGB) available?
