Toon2 unusable since Januari 1st

Post by Tomm1ed »

I've got a rooted Toon2 running 5.49.19 (was running 5.49.16 when issue started and update did not solve) which rebooted by itself on January 1st around 22:00 CET and since is not controllable from the touchscreen.
It looks like qt-gui is the issue since it is using almost all CPU:


top - 03:10:56 up 7 min, 1 user, load average: 1.58, 1.29, 0.66
Tasks: 117 total, 2 running, 115 sleeping, 0 stopped, 0 zombie
%Cpu(s): 94.1 us, 5.6 sy, 0.0 ni, 0.0 id, 0.0 wa, 0.0 hi, 0.3 si, 0.0 st
KiB Mem : 505180 total, 191556 free, 209780 used, 103844 buff/cache
KiB Swap: 0 total, 0 free, 0 used. 277972 avail Mem
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
3491 root 20 0 363824 152596 40180 R 92.4 30.2 1:48.70 qt-gui

Rebooting the Toon does not help and updating to latest version didn't either.
Disk space seems ample as well:
df -h

/dev/root 480.3M 196.6M 258.7M 43% /
devtmpfs 214.2M 0 214.2M 0% /dev

/dev/mmcblk3p5 27.0M 437.0K 25.0M 2% /mnt/persist

Installed apps from Toonstore:
- afvalkalender
- buienradar
- doorcam
- wifiqr

Does anyone have any idea how to fix or recognize this issue?

Hi,
I see a similar case: https://toonforum.nl/d/539-toon-2-hangt ... r-mogelijk

Maybe a logging of the qt-gui information can provide what is happening:
In /etc/inittab change the qtqt line to this (so comment the original line and add the one with output to log file). Then restart

Code: Select all

qtqt:245:respawn:/usr/bin/startqt >/var/log/qt 2>&1
#qtqt:245:respawn:/usr/bin/startqt >/dev/null 2>&1
After restart try to follow the /var/log/qt/ log file (for example: tail -f /var/log/qt) and while it is hanging try to understand from the log what is causing that.

can you also try to manually remove the custom apps one by one from the qmf/qml/apps folder, just to check if one of these is the culprit

Sorry never got the email that my post was live. I saw several errors relating Doorcam so I removed it and that did not help at all. Disabled qt logging and went back to sleep and when I woke up my Toon was fully operational again and I have zero clue what caused it but am happy to be able to use it again :P

See my other message, I did remove DoorCam because of a repeating error:
file://qmf/qml/apps/doorcam/DoorcamTile.qml:22: SyntaxError: JSON.parse: Parse error
but that did not appear to fix things because also after removal I kept experiencing a frozen interface (no animations, no response to touchscreen, no screen sleep and the 100% CPU of qt-gui)
Some hours later (I think I got up around 10:00) the issue had resolved itself somehow.
