Is S905W still supported? Tried on MXQ Pro (newer variant with S905W) and got not booting or boot very slow. Simple iptv addon does not seem to work, I’m getting “Creating simple iptv addon 0%”, black screen every few seconds and finally after 2-3 minutes system freeze, not reacting to anything

It’s not be removed from the officially supported devices wiki yet. Have you tried a clean install. Maybe you have a corrupted SD card.

Clean install on new sd card

This is a great update. The lip sync/stuttering issues are no longer, it’s now basically perfect. Extremely impressive version.

Anyone experiencing wireguard problems lately?

10

I’ve had intermittent nordvpn issues which uses wireguard but seems to be improving.

11

well, I had it running well. But somehow a few days ago after a nightly update over the wireguard conection (can’t call date exactly) I seem to be unlucky. wg0 is ready and connected but no internet over wireguard any more. Tried some things like disabling corelec firewall, tried some iptable commands found over google but it won’t work again. Tried another wireguard to connect to another server but that also didn’t help. Stuck here.

I’m having this in kodi.log:

The governor is set to performance as it always was.

EDIT:

CoreELEC:~ # cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors
ondemand performance
CoreELEC:~ # cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
performance

So it doesn’t seem to be a kernel issue, the governors are there.

Not sure, just ignore it.
It was reworked on Amlogic-ne but I think it will never be fixed in Amlogic-ng.

The “error” does happen on close the file? There is no argument at all:

You have the folder /sys/devices/system/cpu/cpu4... as well?

14

It is on GT King Pro (S922X rev.b), so the cpu clusters are A53 (cpu0,1) and A73 (cpu2,3,4,5).

P.S. Nevermind, I forgot that I use custom script like this, which probably can cause the issue:

CoreELEC:~ # cat .config/autostart.sh
echo "0" > /sys/devices/system/cpu/cpu0/online
echo "0" > /sys/devices/system/cpu/cpu1/online

I disable the “LITTLE” A53 cores, because I’ve found out the device to be noticeably smoother when it is using the “big” A73 cores only.

This fixed DVD playback on my Odroid N2 so thanks!
