I recently bought two Raspberry Pi 4 8Gb.
Both were set up the same to do the same task. I have them plugged into a TV and continually show a web page with a map that tracks our council’s vehicles. I am using the latest version of Chromium.
I am connected to WiFi and have a wired keyboard and mouse plugged in and a HDMI adapter.
One Pi is behaving itself very nicely and the other is constantly freezing. On average it happens after about 20 minutes, but sometimes as short as one minute.
By freezing I mean the keyboard and mouse stop working and the screen doesn’t update. This is easy to tell as the clock gets stuck at the time the Pi froze.
In case it was a software issue I copied the SD from the working Pi on the freezing Pi. Problem continued.
I then swapped the SD cards and the problem continued on the bad Pi. It didn’t move with the SD card. That eliminated the SD card or software as a cause.
I have now swapped the power supplies in case that is the problem but logging something here in the meantime (as the bad Pi is off site).
Any thoughts or suggestions would be appreciated,
