Why does my Raspberry Pi keep hanging up?
The problem is that Raspberry Pi suddenly hangs (no response the keyboard nor mouse, and I’m also not able to ping) after 2-3 days and thus we have to reboot it forcefully. What could be the reason for it to hang?
What does the OK light on Rasberry Pi mean?
You should see flashing of the OK light for ~20 seconds. If that helps, plug in cables one at a time to identify which is interfering with boot. Confirm the USB cable is properly seated in the power slot. The red power LED does not necessarily mean it is fully connected.
Why is the green light on my Raspberry Pi not flashing?
When flashing/blinking the green LED should be as bright as the red LED. The Raspberry Pi cannot find a valid image on the SD card. Turn the board over to check that the card is inserted correctly; the insertion force is much larger than for some laptops.
Why does my Raspberry Pi keep saying black frame?
Figure 2: The strange blank/black frame error. The blank/black frame is a particularly strange problem — frames are being read from the video stream, they are just not being decoded and displayed properly. After your Pi reboots, try re-executing your Python script.
Why does my Raspberry Pi hang on SSH?
So clearly something is sort of working, but I am a bit stumped as to why ssh just hangs. Any ideas? The raspberry pi is very remote (as in a 4 hour drive away in a secluded location with no personnel), so I cannot diagnose locally. And restart sshd (sudo service sshd restart).
Is there any way to recover a Raspberry Pi?
The only way to recover the Raspberry Pi again is to unplug and then plug the power. After the reboot, neither syslog (syslog/messages/kern.log/auth.log or mpd.log) do not report anything. The system is being graphed in Cacti at 5 minute intervals.
What to do if your Raspberry Pi freezes?
The Pi hangs only when playing music, on the 2nd day of uptime. What has been done to eliminate the issue (didn’t help anything of the listed): The mpd is being stopped and started nightly by a cron script. The music files are being played from USB HDD.
How many Python programs are running on Raspberry Pi?
I am running four Python programs 24 hours/day on the Raspberry Pi. Three programs out of four are like background services, which consume at the maximum 2.4% CPU and around 1.2% memory each. The fourth Python code is a pygame application that is displayed on a 1920×1080 screen, which consumes about 50% CPU and 2.4% memory.
Why is my Raspberry Pi 2 not working?
Turned out to be a problem with the power management in the wifi dongle: If you overclocked, double check that and maybe set a lower frequency. One does not simply set “Turbo” or “Pi2” as an overclock in raspi-config.
Is it possible to overclock Raspberry Pi 2?
If you overclocked, double check that and maybe set a lower frequency. One does not simply set “Turbo” or “Pi2” as an overclock in raspi-config. I’ve experienced this with extreme stress testing and a serious overclock.
