RTOS Task Execution Order with Equal Priorities: This question has puzzled many beginners. Today, I will briefly describe it with examples. What is RTOS Task Priority? In an RTOS, each task is assigned a priority. Among all ready tasks, the task with a higher priority executes first. When we create a task, we need to … Read more
Hello everyone, I am the Intelligence Guy~ During the development of RTOS, you must have encountered the issue of priority inversion, where a low-priority task is preempted by a higher-priority task due to shared resource access. This contradicts the real-time performance of a preemptive kernel. The core of solving the priority inversion problem in RTOS … Read more
We previously introduced how to configure OpenWrt to operate in a one-armed routing mode (OpenWrt Configuration One-Armed Routing Mode), and later discussed iStoreOS based on OpenWrt (Deploying iStoreOS on VMware ESXi to Turn It into a Router), which we flashed onto the VMware Edge 620 (VMware Edge 620 Magic Operation: Flashing iStoreOS to Become a … Read more
