Nightly build of 28-07.

After starting downloads (transmission in docker), video output stops. Samsung tv indicates that resolution is not supported.

Libreelec and docker still seems up & running.

Setup:

RPi4, original power supply, wired internet, external ssd (Samsung SSD T5 500GB), single HDMI cable connected, boot via external USB thumb drive.

Logs:

This is most likely caused by this issue: HDMI screen turns off when sustained high CPU usage on all cores · Issue #1598 · raspberrypi/firmware · GitHub - video output stops working when RPi4 overheats.

Make sure your RPi4 is properly cooled (eg heatsink or fan, if you use a case try without it) and/or avoid high workloads until that's fixed.

Thanks for testing! I could reproduce that here and have informed the RPi devs.

Thanks a lot for the logs, I could reproduce the issue now on my Pi 400 and it seems to be a RPi firmware issue.

Can you try updating the firmware files on the FAT partition of the SD card?

Download start4x.elf and fixup4x.dat from here GitHub - Hexxeh/rpi-firmware: Firmware files for the Raspberry Pi , rename them to start.elf and fixup.dat, respectively, copy them over the files on the SD card.

This fixed the issues on my Pi 400, no errors in the log and the (USB) keyboard worked, too.

so long,

Hias

Can you please post logs, both from 9.95.5 and 9.97.1?

ssh in and run "pastekodi" or use the log upload function in LE settings, then post the URLs.

Sorry, but this is not going to happen.

Not only would it be a lot of work (we had to rework kernel/initramfs build process in LE10 for kernel 5.4/5.10 which would all need to be backported) but it would also put us in the same boat as RPiOS with kodi 18 - broken HEVC playback.

See these unresolved issues:

Kernel 5.10 - RPI3 - Kodi 18.x does not play HEVC videos anymore · Issue #4112 · raspberrypi/linux · GitHub

Kernel 5.10 - Kodi does not play HEVC videos anymore · Issue #4380 · raspberrypi/linux · GitHub

We released LE10 RC1 last weekend and the final release is around the corner so just use that - like many other RPi4 users already do.

so long,

Hias

Can you test with the latest nightly from here Index of / ?

If it doesn't work, reproduce the issue, then ssh in, run "pastekodi" and post the URL. Also please post which TV you are using, and if it's connected directly or via an AVR.

Nightly builds (24th and 25th) directly gave issues; reverted back to your build and no issues for now.

I'm not proficient in retrieving log files.

If you could point me to a guide I can share them and provide feedback on the nightly builds.

What kind of issues did you have?

Info on how to get log files is in our wiki: https://wiki.libreelec.tv/support/log-files

I would like too but am using both HDMI Ports, so until that is fixed in the nightlies it‘s a no-no for me

Fair enough. We also hope that's fixed in the RPi kernel soon.

Quote from ApexDE

So, with the next RC the mentioned OOM fixes will be included?

Yes. We wouldn't mind though getting some feedback with current nightly testing

Hias

Quote from Martvdh

Is this change also included in the RC1?

No, it will be in the next release. Please test with nightlies for now.

OOM killer issue should be fixed in latest nightly builds - please read the additional info here RE: Cant play 4K MKV files without crashing and test with the nightly.

so long,

Hias

We've switched the kernel to 64bit, the latest nightly build (currently 20210724) from Index of / already includes this change.

Please test with the official nightly builds instead of my older testbuild.

Note: there's a known bug in the kernel ATM, RPi4 won't boot if both HDMI ports are connected (eg if you use an AVR on the second HDMI port) - this should hopefully be fixed soon.

Also the latest builds enable 4kp60 output by default - if your TV supports 4kp60 but your cable isn't up to spec you may get no signal on TV. In that case add hdmi_enable_4kp60=0 to the end of config.txt to disable 4kp60 support

Just record the stream and see if you can reproduce the crash with the recorded file, then try to narrow it down to a short (30 seconds or so) snippet and upload that somewhere. This will also remove the PVR addon out of the equation.

Lots of us devs don't use or even have access to a PVR setup at all and we really need a short sample to look into such issues.

so long,

Hias

ghtester that crash log looks like it's something else, never seen that though.

If possible try to reproduce it with a small, local file and then upload that somewhere so we can try to reproduce and analyse the issue as well - PVR addons, corrupted streams etc add lot of points where things go wrong, that's not something we can easily look into.

In general always use the log upload function in LE settings or the "pastekodi" / "pastecrash" scripts as they also include the journal, config.txt and other settings that are important to us, in addition to just the kodi (crash) log. More often than not the kodi (crash) log alone is not enough to kmow what went wrong.

so long,

Hias

ghtester please always post "pastekodi" and/or kodi crash logs if you run into issues - as mentioned in the sticky in this forum - otherwise we have no idea what's going on.

RPi4 has a known issue of the OOM killer kicking in which will be resolved by switching to a 64bit kernel - see here RPi4: switch to 64bit kernel by HiassofT · Pull Request #5507 · LibreELEC/LibreELEC.tv · GitHub - if you had provided a "pastekodi" log I would know if it's the same issue or a different one.

With the milhouse build the firmware couldn't read the edid either but it seems it fell back to a safe 640x480 mode and also provided a 1920x1080 mode.

Please test the latest nightly with a known good HDMI cable (eg the one you used with the monitor) and your projector.

If that still doesn't work you can add the following parameters to cmdline.txt as a workaround, that should give you 1920x1080p60 output:

drm.edid_firmware=HDMI-A-1:edid/1920x1080.bin video=HDMI-A-1:D

so long,

Hias

MikeKL thanks!

I could reproduce the issue, the new kernel hangs during boot if two HDMI devices are connected (checked that here with two monitors).

It's a bug in the kernel, the same thing happens on RPi OS with the latest rpi-update kernel. I've opened a github issue here RPi4/kms: boot hangs if two monitors are connected · Issue #4465 · raspberrypi/linux · GitHub

Until that's resolved stick to the previous nightly build or leave the second HDMI unconnected.

so long,

Hias

samba working but ssh not is odd, nothing changed in that area. Are you sure it's enabled and worked with the previous build?

I'd recommend rolling back to the previous build, connect both the TV and the AVR and then grab the edid of both devices, then I'll see if I can reproduce the issue here.

run

cat /sys/class/drm/card0-HDMI-A-1/edid > edid-tv.bin
cat /sys/class/drm/card0-HDMI-A-2/edid > edid-avr.bin

and then upload the edid-tv.bin and edid-avr.bin files (put them into a zip so the forum software allows attaching it).

EDIT: ah, and please post pastekodi and modetest from the previous build, too.

so long,

Hias
