  1. Stories and reasoning we put to our work is often not that visible. Here is my Link project, which is partly AI implemented communication system to test various transport and security measures. It's built with buildroot and all other details can be found here: codeberg.org/resiliencetheatre

  4. After countless trials, books, web searches, and some brutal advice from my Bukowski AI, I finally built a custom IoT hotspot from scratch using Buildroot 😎

    No more pre-packaged garbage. I filter insecure connections myself. Total control 💪🏻

    The first prototype works... mostly 😆

    Now comes the real torture: testing and refining 🫩

    Maybe I'll even try to sell this thing 🤑

  5. Does anyone know how to report errors to https://db.gcve.eu/? Just their info@ mail? I looked up CVE-2026-6042 and CVE-2026-40200 there because I was annoyed that the NVD database (which #Buildroot uses for automated vulnerability checks) still didn't have them correctly labeled with the CPE (so automated tools can't identify the package is vulnerable).

    Result:
    CVE-2026-40200 is correctly labeled (good!), while CVE-2026-6042 is not (different vendor/product). Mistakes happen, an organization that's trying to run as serious vulnerability DB really needs to provide an obvious "report errors here" mail address (or other means, but really… mail). ​:neocat_glare:​ #CVE #GCVE

  6. Training code for embedded Linux development resilience. Resulting communication system with selectable one-time-pad for codec2 based fullduplex or symmetric crypto for push-to-talk usage.

  7. Compiling yet another Buildroot image I’m 99% sure will fail… but at least this time the soundtrack is Sunshine by Alice in Chains, so the suffering feels poetic ❤️

  12. Trying to build a GUI Linux distro with Buildroot. Just Buildroot. No Debian, no Arch. Just pain 🫩

    Xorg? Black screen. Wayland? Sounds like a fantasy novel. Kernel panic? Oh yeah, got that too 🫨

    But I will make this work, because minimalism deserves a desktop 🤟🏻

  13. Some of these dongles actually work on #zeST. But:
    - with an outdated stable release of #Buildroot from 2024.
    - with an outdated #Linux kernel from 2023.

    So older devices may be working, newer devices absolutely not.

  14. After way too many attempts, I finally got a custom GRUB2 EFI bootloader built with Buildroot showing a splash image at boot on real hardware 🎉

    The secret? insmod gfxterm_background + font in the right path.

    Simple in theory, painful in practice 🤕

  19. So, Infix OS has been upgraded to 2026.02 LTS well in time for our 26.03 release. We've actually been tracking it since -rc1, so this was more of a formality to rebase and rerun our regression tests. Mattias (lazzer) worked relentlessly on this, while still managing to do a ton of other things as well.

    Looking forward to our next release, hopefully my BPi-R64 porting work will be done by then as well 🤩

  20. Next challenge at #BashLab: build an AI assistant for creating live OS with #livebuild.

    I already built one for #Buildroot and one for #Pentesting.

    Problem: no solid PDFs for live-build, only the official HTML docs with tons of links.
    Now I need to feed the entire site into my RAG.

    Time to scrape, structure, and index 🤟🏻

  21. Working on a Buildroot OS with kernel 6.18 + PREEMPT_RT on an Intel AX210 WiFi (iwlwifi QuZ firmware). With dynamic preempt everything works, but RT causes firmware init errors and the device disappears. Maybe bleeding-edge RT kernels aren’t always the best choice. Curious if others hit similar issues or found workarounds. Open to discussion.

  22. Today we finished another huge milestone for our little operating system. Another release of a completely open and free system based on Linux.

    A task that just twenty odd years ago would have been extremely hard to pull off. We’ve managed to do it for three years now, and with a small yet highly skilled team.

    Automation, and designing the architecture for automation with YANG, really is the key to our success.

  23. Milestone unlocked 🚀

    Built a custom Linux system with Buildroot + PREEMPT_RT on x86_64, fully functional and minimal, supported by a local AI assistant with RAG, trained on official docs: no hallucinations, only grounded answers.

    Real-time Linux, reproducible builds, full control.

    This one feels big.

  24. A request came in to add iperf3 3.20 to BashCore.

    iperf3 is a solid, widely used tool for real network performance testing (TCP/UDP, throughput, jitter, loss...).

    I started using it recently while working with Buildroot, and it fits BashCore’s minimal approach very well.

    It will be available soon in upcoming BashCore releases 😉

  25. Update after longer run (~10M cycles): max jitter reached 55 µs 👌🏻

    Plugging in AC power caused a localized spike on a single RT thread (51 µs), while others stayed stable.
    Classic ACPI / power-state event: bounded, localized, fully recoverable.

    Determinism preserved under real hardware events 👊🏻

  26. Built a custom RTOS with Buildroot + Linux 6.12 RT. Tested on an old Celeron dual‑core over SSH, Wi‑Fi on, and stress‑ng running.

    Max jitter: 39 µs (!)

    Same hardware, same kernel on Debian 13 RT in “clean lab” conditions… also 39 µs.

    Real‑world vs lab, same result. Buildroot wins in determinism 🏆

  27. 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 👊🏻

  28. 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: 118us

    The kernel isn't even stable yet, but this real-world performance is already production-ready. We are ready for the future of #RTLinux. 👊🏻

  29. 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. 🐧⚙️

  30. Built a custom Buildroot distro for #Raspberry Pi 4 running:

    Linux 6.12 PREEMPT_RT, Wi‑Fi, #NordVPN, #Tor + #Proxychains, #macchanger, #nftables, #nmap, #netcat, #watchdog.

    A real‑time, stealth, weapon‑grade network appliance.

    Minimal. Fast. Untraceable. Mine 👊🏻

  31. A year ago I was experimenting with Debian netinst and live-build, trying to understand boot, init, and live systems.

    Today BashCore is a set of minimalist Debian-based live ISOs (CLI/GUI, optional PREEMPT_RT).

    In 2026 the focus shifts to Buildroot: reproducible systems, RT Linux, and minimal OS design for real workloads.

    Happy New Year to everyone!

  32. Spending my Xmas holidays in the best way possible: deep diving into my custom BuildLab! 🛠️🐧

    Running Debian 13 (via live-build) on one USB stick, compiling Buildroot projects onto another. 4 days of uptime and it’s smooth as silk.

    Currently practicing with RTOS for x86 and Real-Time Linux (PREEMPT_RT) for Raspberry Pi. There’s nothing like the smell of fresh cross-compiled firmware in the morning! ☕

  33. Just fired up my new RTOS Linux 6.12 RT build with Tor, ProxyChains, and Lynx. 🚀

    Opened dnsleaktest.com and... surprise!

    I’m showing a Swedish IP! 🇸🇪🧑‍💻

    Unfortunately, I'm not in Sweden, but hey, who can complain? The build works flawlessly!

  34. @itsfoss
    ##LFS, #Gentoo, #Yocto, #buildroot , I could go on. Incidentally, what is that appliance/PCI card/etc. running?

  35. 🚀 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 zero

    This #RPi4 is now a deterministic beast. 🐧🛠️ 64-bit RT Linux at its best!

  36. Just built a custom x86 Real-Time OS with #Buildroot! 🚀

    Boasts a blazing-fast 2-second boot on QEMU, now ready for bare metal. This #RTOS is super lean on RAM & CPU, perfect for embedded & low-latency apps.

    Thrilled with the #LinuxRT kernel (6.12.57-rt14)! Check out the screenshots for proof.

    What a journey!

  37. VICTORY! 🏁 After a long battle with kernel patches and expert modes, the BashLab has officially spawned a #RealTimeLinux system! 🐧⚙️

    Running Linux 6.1.158-rt58 on #QEMU via #Buildroot. From 'urban legend' to PREEMPT_RT reality. Never underestimate the power of a clean Ext4 partition and the Expert Mode! 🤓🎒 #EmbeddedLinux #LinuxKernel #RTOS #OpenSource #Hacking

  38. My journey to a #RealTimeLinux kernel for #AMD64 on Buildroot continues!

    Many failed experiments with different kernel/RT patch combos (6.18, 6.12, 6.1), but learning a ton about patching & Buildroot quirks. Still stuck on enabling CONFIG_PREEMPT_RT, but feeling closer to the breakthrough!

    My portable #BashLab is ready for more. 🤓

  39. Built a custom Raspberry Pi 4 RT OS using Buildroot.

    Manually downloaded the Raspberry kernel (6.12.61) and PREEMPT_RT patch (6.12.57), applied locally and produced a bootable SD.

    It works.

    No GUI, CLI tools only, deterministic boot and real-time behavior.

    Learning by doing 🤓

  40. Just learned there's a whole middle ground between a dynamic kernel and full RT. All this time I thought it was binary: either “YOLO scheduling” or “monk‑level determinism”. Turns out Linux ships with a surprise third option. The more you know… and the more you recompile.

  41. 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. 🚀

  42. 🤞 My #RaspberryPi 4 kit just arrived and the first build is already crunching on my i7/32GB host.

    Booting #BuildLab OS from USB via #Ventoy, compiling #Buildroot on a second USB.

    Fingers crossed for the first sdcard.img soon!

    #Linux #Embedded #OSBuilder #DevLife #NerdMode #raspberrypi

  43. 🤟🏻 Built a full #sdcard.img for #RaspberryPi in 28 minutes with #Buildroot using BuildLab, my new portable live OS booted via #Ventoy.

    1800 packages, XFCE, QEMU, libvirt, full toolchain, debug + network stack.

    #BuildLab isn’t a system to use, it’s a system to build systems. A clean, reproducible embedded lab always in my pocket 👊🏻
