VxWorks – the Wind River’s VxWorks and Tornado real-time OS (RTOS), microkernel based, POSIX and ANSI C language compliant. VxWorks is a real-time operating system (RTOS) developed and marketed by the American company Wind River Systems https://archiveos.org/vxworks/ #operatingsystem #rtos

On i.MX8MP, GPIOs are owned by Linux (A53) by default.
If the Cortex-M7 needs them—especially for interrupts—you must release them in the device tree:

• Remove pinmux
• Remove GPIO references
• Disable the GPIO controller if needed

This prevents A53/M7 resource conflicts and ensures real-time reliability.

OK8MP Development Notes | Detailed Method for A-Core GPIO Pin Release

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 👊🏻

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 🏆

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! ☕

#FreeRTOS vs #Zephyr is something I hear a lot. The reality is that they're different tools for different jobs. I've written down some of my thoughts after using them both.

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!

Pech или pyRTOS: вот почему «печка» лучше чем «аналог FreeRTOS»

Pech — это Managed Kernel которая следует концептам Mach 3.0 . В 2025 году безопасность важнее ручного управления тактами. Я использую высокоуровневый рантайм для создания математически безопасной среды , где баги памяти устранены на уровне архитектуры. Это то, к чему сейчас стремятся проекты вроде Microsoft Singularity или современные ОС на Rust. В этой статье я попытаюсь как можно больше перечислить ошибок pyRTOS которые были исправлены в Pech.

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

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. 🤓
