Die letzten Jahre habe ich LibreElec auf einen RPI 3/4 als meine Smart-TV Lösung für meinen großen NoGIS-Fernseher verwendet. Ja, damals musste man in Österreich noch die GIS-Gebühr für den Fernseher bezahlen.
Jedenfalls vor einer Woche begann es mit Ton-und Bildausfällen.
Habe mich erst heute zu einer Fehleranalyse motivieren können. Aus irgendeinen Grund funktioniert es ohne Probleme im Wohnzimmer am 32" Fernseher.

Seit ein paar Tagen ist mein Media-Center Libreelec am Raspberry PI nicht mehr verwendbar. Kein Ton bei Live-TV oder Streaming; alle paar Sekunden wird der Bildschirm schwarz und nach einiger Zeit ist die grafische Benutzeroberfläche aufgrund von Grafikfehlern nicht mehr bedienbar.
Hoffe es ist nur das HDMI Kabel und nicht der RPI selbst. Bei den enormen Preisanstieg weiß ich nicht, ob ich mir nochmals einen Raspberry PI zulegen werde.

I'm having trouble with my #RPi4 again. #Debian updated the Linux kernel a few days ago to 6.12.90 (a security update); since then I've been getting segfaults, and when it reboots sometimes I get a kernel panic.
Not really sure what to do; I could update the image on my SD card.
I've been running Debian Stable for maybe 20 years. This is the first time I've had such problems.

PiStorm/Raspberry Pi 4: emu-genet 3.8 and gic400.library 1.3
Owners of a PiStorm turbo card with a Raspberry Pi 4 have two updates available - the emu-genet network driver for the Raspberry Pi 4B is now available in version 3.8 and the gic400.library used for interrupt handling in version 1.3.

Week-end glande, J'en profite pour refaire mon serveur rasp pi 4.
Après 3 essais :
1- OMV7, que j'ai pété en voulant héberger funkwhale
2- nextcloud en direct sur raspbian, conflit d'accès
3- casaos, modifications compliquéesRetour a OMV8 + docker. Simple, efficace.

Anyone knows why ARM boards don't use simple things like Open Firmware (https://www.openfirmware.org/Open_Firmware.html) instead of the mess they use to boot?

Powered off my #homeassistant #rpi4 today to change the fan.
re-powered ... and NOTHING.
turns out, the SanDisk A2 U3 #microSD is now completely fried.
Can't even be access anymore. SD-card readers just give up completely.Really glad I did not use #hass default backup automation, but regularly pull backups to a separate server with my own script :-)

Restoring took a long while, but went smoothly.

Сеть вместо SD-карты: как собрать минимальный Linux для Raspberry Pi с возможностью загрузки по сети
Когда собираешь и тестируешь свой Linux для одноплатника достаточно долго, начинаешь замечать, что деплой Linux на SD-карту — монотонная повторяющаяся последовательность действий, занимающая ценное время, в которой легко совершить ошибку. К тому же больно видеть, как исчерпывает свой ресурс SD-карта и слот для неё. Часто при embedded-разработке эти проблемы решают при помощи сетевой загрузки Linux. В этой статье я расскажу, как организовать сетевую загрузку для Raspberry Pi и собрать минимальное ядро Linux, поддерживающее сетевую загрузку. Сетевая загрузка рассматривается для Raspberry Pi 3 Model В и Raspberry Pi 4 Model B, которые я далее называю общим термином Raspberry Pi или более ласково — малинка. Основное назначение окружения для сетевой загрузки — ускорение отладки и тестирование пользовательских приложений и программ разрабатываемого дистрибутива Linux. Тема сетевой загрузки довольно многогранна и затрагивает несколько уровней стека — от протоколов локальной сети до особенностей загрузчика Raspberry Pi. Я старался изложить материал максимально просто и последовательно, но если у вас нет базовых знаний о работе локальных сетей (DHCP, TFTP), протоколах TCP/IP или процессе загрузки Linux, некоторые моменты могут показаться сложными. Статья является продолжением моей предыдущей статьи , где я рассказывал, как создать минимальный Linux для Raspberry Pi, который грузится с SD-карты. В свой репозиторий я поместил исходный код Docker-образов, упрощающий сборку минимального Linux и настройку окружения для сетевой загрузки. Надеюсь, что статья сэкономит вам время, которое вы сможете потратить на свой увлекательный проект.

75 MILLION cycles & 24h stress test: PASSED.
Final verdict on #RaspberryPi 4 + #Buildroot + Linux 6.19-rc1 PREEMPT_RT:
Max jitter: 118us (under heavy stress)
Max jitter: 70us (post-stress/idle)Perfect recovery, zero drift, and absolute determinism. This $50 setup is officially outperforming industrial hardware 10x its price. The future of #RTLinux is here 👊🏻

30 MILLION cycles. Max jitter: 118us. Solid as a rock. 🏁
Final report on my #Buildroot + #RaspberryPi 4 setup with Linux 6.19.0-rc1-v8 PREEMPT_RT.
After 8+ hours of torture:
🔥 stress-ng (2x VM workers)
📶 Active SSH over Wi-Fi
📊 Avg Jitter: 14us | Worst Case: 118usThe kernel isn't even stable yet, but this real-world performance is already production-ready. We are ready for the future of #RTLinux. 👊🏻

Built a custom #Buildroot system for #RaspberryPi 4 running the brand new #Linux 6.19.0-rc1-v8 with PREEMPT_RT! 🚀
Real-world stress test:
1M cycles with cyclictest
2x stress-ng VM workers (1GB RAM)
Active SSH over Wi-Fi📊 Results: Max Jitter 118us (Avg 14us).
Pure magic to see this level of determinism on a bleeding-edge kernel before its official release. Stable, lean, and mean. 🐧⚙️

🚀 Rock-solid Real-Time performance on Raspberry Pi 4!
Just stress-tested via SSH a custom #Buildroot (Kernel 6.12.61-v8 #PREEMPT_RT). Even with a massive memory hog running (stress-ng --vm 2 --vm-bytes 1G), the results are insane:
🔹 Avg Latency: 14µs
🔹 Max Latency: 42µs
🔹 Jitter: Virtually zeroThis #RPi4 is now a deterministic beast. 🐧🛠️ 64-bit RT Linux at its best!

Success! 🎉 Just finished building a custom Linux OS for my Raspberry Pi 4 using #Buildroot (raspberrypi4_64_defconfig).
SSH access is fully configured, network is up, and I'm connected remotely! This minimalist embedded system is flying. Time to start the real customization. 🚀

My #RaspberryPi 4B is acting up and I think it's data corruption(?) from not powering off properly when it stopped responding. I really need to buy a switch to shutdown safely...
I formatted the SSD (SMART status seems ok), flashed the latest #DietPi and slowly setting back my services.
This is a great chance for me to actually sort out the messy initial setup of experimenting with #SelfHosting I'm in the process of setting up a #cron job with #rsync, #syncthing & dietpi-backup now. 🤞#Rpi4

I kid you not, just did a moto24 - #raspbian #rpi4 sftp transfer via #termux because #bluetooth could not connect.
Twa's literally faster to type in than wrestle demons of #ui.
There was someone lately as had said that he doesn't like the #cli and good riddance? My dude! Looks like you could never run your fingers over it proper.
Lazy day today. Did an exercise I was putting off. Turns out it was quite simple in the end.
'kay off to bed.. night night..

In other exciting home sysadmin news, I have a problem in the #RPi4 box I use as the router for the local WiFi network: periodically, some clients disassociate, and then can't reconnect. (I don't really know why.) The general solution is to restart #hostapd. But I don't want to do that manually all the time.
I have now set up a service to restart hostapd automatically if it cannot successfully ping one of the other boxes. It runs with a systemd timer. Things seem better now.

Major upgrade today for #Jellyfin. They are changing how their database is used, so the upgrade may run for hours.
Note further that the upgrade requires the relevant partitions to have at least 2G free. On my #Debian #RPi4, I had to increase the size of /tmp in order for the upgrade to proceed.

**Update:** It took about two minutes on my box, after I increased /tmp.

@q7mJI7tk1 I have #Pihole and #unbound both running on an #RPi4 for over a year. Solid as a rock although new domain lookups take much longer the first time. After that they’re cached. About 6.5 to 7.5% of the #DNS queries get blocked. I’m super happy with the setup.

Yall talk about #solarpunk, so here's a glimpse of my new LE setup to raid BBSes at night. And srsly, 15" is more than enough if you know what you are doing 😏
Shoutout to paulie at #20forbeers . I'll get ya that 20 mate, promise honest to godess 🤘

@Mr_Dr_Oink
The #RPi4 includes 2xUSB3.0 ports (color blue). Internally, the Pi 4’s USB 3.0 ports (and also the USB 2.0 ports and Ethernet) are attached via a USB controller which itself is connected over a single PCIe bus. All USB traffic must share that internal link. Throughput is limited in the range of 200-400 MB/s.
The #RPi5 has a single-lane PCIe 2.0 link exposed via a 16-pin FPC (flat flex cable) connector. Devices can be attached via HATs that adapt that PCIe lane into M.2 or PCIe slots.
