The world of embedded systems seems to be composed of two types of developers: those who love real-time operating systems (RTOSs) and those that despise them,| Shawn Hymel
Are there any opensource/free Unix like RTOS that can run a virtual machine like QNX Neutrino RTOS (http://www.qnx.com/products/evaluation/eval-target.html)?| Unix & Linux Stack Exchange
Back in October last year, I wrote a bit about why we wrote a new RTOS for CHERIoT. Reading that again, I realise that it had a lot of high-level concepts but missed out on some detail. This time, I wanted to take a closer look at some CHERIoT RTOS features to show that being able to rely on CHERI lets us build them in fundamentally different ways to other systems.| CHERIoT Platform
Blocking occurs every time a program waits in line for something to happen. For instance, the basic Arduino “Blink” example turns the LED on and calls the delay() function to wait for a timeout event in 1000 milliseconds. Then it turns the LED off and calls delay() to wait in line for another timeout event […]| Modern Embedded Software | Quantum Leaps
Is it possible to be agile and do modeling, state-machine design and code generation? You bet! Modern event-driven approach with asynchronous active objects, hierarchical state machine and visual modeling will let you go faster and avoid many bugs by design. Please listen and comment! NOTE: The Agile Embedded Podcast is run by Luca Ingianni and […]| Modern Embedded Software | Quantum Leaps
The Zephyr Project is an open-source real-time operating system (RTOS) focused on embedded and IoT platforms. Zephyr is a Linux Foundation hosted ‘Collaboration Project’, and supports a wide array of devices and architectures. The Raspberry Pi Pico is a microprocessor board developed by Raspberry Pi and is based on their RP2040 chip. The RP2040 is …| www.thegoodpenguin.co.uk
The CHERIoT compartment model is similar to an object-oriented model, where each compartment exposes a set of entry points (analogous to methods) that can be called by other compartments. This works well for compartmentalising a lot of libraries: just expose their public API as compartment entry points.| CHERIoT Platform
