Along with a log it might be beneficial to know a few other things.

When the stream freezes, do you have control of LibreElec with a keyboard, mouse or a remote control device or are they frozen too? That is, do you have to remove power from the Raspberry Pi to revive LibreElec?

When the stream freezes, is there any activity of the green OK/ACT LED on the Raspberry Pi? That's the SD card activity indicator. Any toggling of that light-emitting diode shows that there is some process still running. LibreElec isn't completely frozen.

If you have an Ethernet connection to the Internet, take a look at the two LEDs at the RJ45 connector on the Raspberry Pi. The yellow 10M/100 indicator is probably on showing a valid connection. Is the green LNK LED flashing? That indicates some data transmission in progress.

PS: If you use a MicroSD XC card, that could be the cause of your crashes.

I just checked. It is an HC card.

As suggested I have run a series of tests on my Raspberry Pi 3 hardware. The memtester tests showed no errors over 5+ loops (condensed below).

The power supply also passed.

LibreELEC:~ # vcgencmd get_throttled
throttled=0x0

My power supply is a Canakit Model DCAR-052A5 that is rated at 5 VDC output at 2.5 amperes. Using a Fluke 8022A multimeter, I measured 5.05 VDC at the Raspberry Pi. That is within the range of 4.75 to 5.25 VDC required by the computer.

It is unlikely that the hardware is a problem. I have been using this configuration since February of 2017 through several iterations of LibreElec (and probably some versions of the earlier OpenElec).

This freezing problem is new to me. I don't recall seeing this behavior until LibreElec version 8.95.003 or perhaps 8.95.002.

I have italicized freezing because it might be a misnomer. On the surface it looks like LibreElec has frozen or locked up. The stream stops. The software is unresponsive to a remote control and to the USB-attached keyboard. Communications with LibreElec is not possible with FTP. On the other hand, I have noticed that the Raspberry Pi's SD Card Activity indicator continues to flash. Something's going on in there.

I see this behavior only during a program stream. It seems that the buffer runs out of program material and playback stops. LibreElec closes its ears to the outside world but is busy doing something. Unfortunately it is too occupied to write a crash log. What changed in this 8.95.xxx series?

Please check your MicroSD card.

I have a SanDisk Ultra 32 GB Class 10 SD card in my Raspberry Pi 3. I removed it from the Raspberry Pi and copied the image to a backup directory on my Linux desktop computer. Then I ran a badblocks read/write test on the SD card.

# sudo badblocks -o ./badblocks.list -w -s -v -b 4096 -c 16 /dev/sdd
Checking for bad blocks in read-write mode
From block 0 to 7791743
Testing with pattern 0xaa: done

Testing with pattern 0xff: done
Reading and comparing: done
Testing with pattern 0x00: done
Reading and comparing: done
Pass completed, 0 bad blocks found. (0/0/0 errors)

There were no reported errors and the badblocks.list file is empty.

(Also, for what it's worth, the MD5 check sums for the LibreElec image on the SD card and the image backed up to the Linux machine matched.)

Finally I restored the LibreElec image from backup to the SD Card, placed it in the Raspberry Pi and booted the device. LibreElec 8.95.003 is running again.

It appeared that I was having the same problem as kevtuning. He didn't step up with a log as suggested by Da Flex so I tried to provide one.

Shall I move my installation up to 9.0.0 now or leave it at 8.95.003 for further diagnostics?

Shall I remove the modified cache settings from my advancedsettings.xml file?

...the next step is activating log level 1 and reading kodi.log for errors.

In an attempt to track down this freezing problem, I modified my /storage/.kodi/userdata/advancedsettings.xml file to enable debug logging.

<advancedsettings>
<loglevel>1</loglevel>
<cache>
<memorysize>73400320</memorysize>
<readfactor>20</readfactor>
<buffermode>1</buffermode>
</cache>
</advancedsettings>

Today my stream of a television program stopped at about 4 minutes, 50 seconds from the start. I couldn't use the Yatse remote app on my tablet computer to do anything with LibreElec. The keyboard attached to Raspberry Pi USB port also did not work. The only way I could revive LibreElec was to remove DC power from the unit. When I plugged the Raspberry Pi's power supply back in, LibreElec booted as expected.

Then I went to the desktop computer on my local area network to open the /storage/.kodi/temp directory on LibreElec. I found the new kodi.log file there but a crash log was apparently not created.

Next, in LibreElec, I went to Settings > LibreElec > System > Submit Log > Upload Latest Kodi crash log. That file pasted successfully and what little there is can be found at http://ix.io/1zma.

Then I tried to upload the latest full Kodi.log suite created since the power-cycle reboot. That failed three times with the error message, Failed to Paste Logs, Try Again. (It might be that a 4.6 MB log is too large.)

Finally I rebooted LibreElec and once again tried Settings > LibreElec > System > Submit Log > Upload Latest Kodi log. This time it was successful. You can see that log here: http://ix.io/1zme.

I restarted the television program I was watching and it finished without further interuption.

Can you see anything in the logs that might lead to freezing or the inability to create a crash log?

System Information

Internet Source: Frontier Communication DSL line through a Netgear D2200D gateway. The LibreElec is fed from a port on the gateway over powerline network using a pair of TP-Link 200 MBps modems.

Raspberry Pi 3 Model B, Micro-SD Card - 32 GB

LibreElec Version 8.95.003 9.0

I agree with bluenote. There exists some fraction of us for which the auto update has not worked for a while. I've been running LibreElec 8.2.2 on my Raspberry Pi 3. After version 8.2.3 was announced and the canary period passed, I would periodically reboot the device. The automatic update to version 8.2.3 never happened. (I verified that my configuration was set to wait for network connectivity before booting.)

After a few days, I downloaded the update file to my desktop computer and transferred it to the Raspberry Pi's update folder to do the manual update. When I rebooted the Raspberry Pi, version 8.2.3 installed as expected. If my memory is correct, I had to manually update 8.2.2 also.

It looks like LibreElec version 8.2.1 is available on the Download page.

You can disregard this posting. I found that the cable I was using was miswired. The description on the Amazon Website was correct for the Raspberry Pi but the cable I received had the video and ground conductors reversed! Be wary of any cables manufactured by HDE.

I am attempting an installation of LibreELEC on a Raspberry Pi 3, Model B. I have tried both version 7.0.3 (LibreELEC-RPi2.arm-7.0.3.img.gz) and 7.95.2 (LibreELEC-RPi2.arm-7.95.2.img.gz). Each was installed using the LibreELEC.USB-SD.Creator.Linux-64bit.bin software.

Both installations appear to boot and I get some audio effects when hitting the USB-attached keyboard's arrow keys, for example. I see the red power LED on the Raspberry Pi with occasional flashes of the green LED. The network LEDs indicate a good connection there.

In both installations, I have no composite video. There is no HDMI device attached. All my attempts to get the video working have been unsuccessful. The cable appears to be good. (I actually see some crosstalk in the video when the Raspberry Pi emits those tones during boot.)

I have held the shift key down during boot. No video.

I have hit the numeral '4' key during boot. No video.

I edited the SD card's config.txt file on my desktop computer and added these two lines:

sdtv_mode=0
hdmi_ignore_hotplug=1

I did not change this commented-out line:

# hdmi_force_hotplug=1

Still no video.

On a side note, I tried to go in through SSH and that was blocked:

ssh [email protected]
ssh: connect to host 192.168.1.43 port 22: Connection refused

I can connect through Samba over the local network in a browser with:

smb://192.168.1.43/

but that doesn't do much except confirm that the connection is live. I can show the directory structure.

Attempts to connect through PuTTY are also blocked.

The Installing LibreELEC on the RPi page states, "...connect the RPi to your TV and power it on. If all went well you will end up directly at Kodi." What if it doesn't work? Is there a troubleshooting procedure somewhere?

What's the method to get the analog video output to work?
