[SlimDevices: Unix] piCorePlayer 6 and watchdog timer?
Every few weeks my pCP 6.0 + Pi touchscreen device freezes. Is it possible to use the Pi's hardware watchdog to force quick, automatic recovery? FWIW I'm using a 3B+.

Thanks. I may give this a try -- the diagnostics shows the bcm2835_wdt kernel module is being loaded, so it seems it should just be a matter of making sure startup kicks off a script that repeatedly touches /dev/watchdog. owner of the stuff at https://tuxreborn.netlify.app/ (which used to reside at www.tux.org/~peterw/) Note: The best way to reach me is email or PM, as I don't spend much time on the forums. *Free plugins:* AllQuiet Auto Dim/AutoDisplay BlankSaver ContextMenu DenonSerial FuzzyTime KidsPlay KitchenTimer PlayLog PowerCenter/BottleRocket SaverSwitcher SettingsManager SleepFade StatusFirst SyncOptions VolumeLock peterw's Profile: http://forums.slimdevices.com/member.php?userid=2107 View this thread: http://forums.slimdevices.com/showthread.php?t=113247 ___ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix

Huh, so the watchdog timer wouldn't help there. Nor, I guess, would daily restarts of Squeezelite. But how would you recommend restarting jivelite? Just 'sudo killall jivelite' and let /opt/jivelite/bin/jivelite.sh respawn it? How stuck does jivelite get? ISTM it should be pretty easy to modify it to do something like "touch" a RAMfs file periodically, and then the jivelite.sh shell script could notice if that file was too old, indicating a hung jivelite process? owner of the stuff at https://tuxreborn.netlify.app/ (which used to reside at www.tux.org/~peterw/) Note: The best way to reach me is email or PM, as I don't spend much time on the forums. *Free plugins:* AllQuiet Auto Dim/AutoDisplay BlankSaver ContextMenu DenonSerial FuzzyTime KidsPlay KitchenTimer PlayLog PowerCenter/BottleRocket SaverSwitcher SettingsManager SleepFade StatusFirst SyncOptions VolumeLock peterw's Profile: http://forums.slimdevices.com/member.php?userid=2107 View this thread: http://forums.slimdevices.com/showthread.php?t=113247 ___ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix
Re: [SlimDevices: Unix] piCorePlayer 6 and watchdog timer?
Jivelite lockup is related to timer variables overflowing in the jive code that occurs every 24 days +20:31 . Affects the radio, touch and controller as well. See 'this thread' (https://forums.slimdevices.com/showthread.php?111650-Spontaneous-turning-on&p=966705&viewfull=1#post966705) for a discussion. To avoid it I use this custom cron command in pcp to restart jivelite twice a month. Code: 30 2 5,21 * * pkill -x /opt/jivelite/bin/jivelite We would need implement a watchdog semaphore in jivelite similiar to 'that in squeezeplay on the hardware players' (https://github.com/Logitech/squeezeplay/blob/public/7.8/src/squeezeplay/src/ui/platform_linux.c#L145) and then run a watchdog daemon at boot in pcp to monitor jivelite and restart as needed.

FWIW, the cron job restarting jivelite has also proved insufficient for me -- several days ago my screen froze so I enabled the scheduled reboot tweak, set to do so once a week. IIRC, when my screen froze most recently the PcP was still responsive enough that I could use the web interface to reboot it. I haven't tried setting up anything like remote syslog so I don't know if the watchdog timer has ever kicked in for real; as far as I know, it's just the Jive UI that's getting messed up, and it has not been frequent enough to motivate me to investigate further. I do kinda wish I'd SSHed in the other day and at least looked around some before rebooting.

Tx - I've enabled the weekly PCP reboot option now too. Yes the UI works fine, just the display is frozen.

If jivelite is frozen and the pcp web interface still works, any logging you enable won't likely help. I've been chasing this issue for years and the only helpful log messages are only written to the console when you run /opt/jivelite/bin/jivelite from an ssh session. I run the screen utility with a 1 line buffer to keep the jivelite ssh session running without needing to keep the terminal window open for weeks at a time. I've narrowed down the crash to the SDL 1.2.15 library and have been testing a pcp7 64bit jivelite build using the yet to be released 1.2.16 for several months without a crash.

Jivelite, Shairport) may need to be reloaded." and I'd guessed that extensions would be reloaded anyway after a reboot after a pcp upgrade. Are you saying that some/all extensions need to be manually *updated* after an in situ upgrade (via the "Patch Update" button)? Is this a commonly known "feature" ?

Yes, both jivelite and shairport are not upgraded automatically. Tinycore doesn't support version info directly, only the extension checksum is used to determine if an update is needed. There is version info available in the repo for extensions, however, it's not downloaded. You can compare the local md5sum files for jivelite with the repository, but it's much easier... to in the jivelite section of the tweaks page there's an update button which will update all jivelite components that are "out of date".

Updating lirc won't make a difference as it only has a fix for irrecord and SDL is bundled in the jivelite extension.
