This article mainly shares the implementation of simple Asymmetric Multi-Processing (AMP) core-to-core communication using FreeRTOS message buffers, taking the STM32H7 (M4 and M7) dual-core processor as an example. 1. Overview The communication … Read more
First, let me clarify that MPU has many meanings, and there are two common ones: MPU:Memory Protection Unit; MPU:Microprocessor Unit; Additionally, some may associate it with modules like MPU-6050. So, please do not confuse MPU. Why Use MPU? If you develop embedded projects that suffer significant economic losses or major accidents due to memory overflow … Read more
In business, “must” represents the minimum requirements for market participation. Today, there are over a hundred open-source and commercial RTOS in the embedded market, most of which lack functional safety certification. Given this, it is clear that RTOS functional safety certification is not yet a “must” today, but perhaps it should be. RTOS is the … Read more
Do you all know if anyone has ever worked on low-power products? Low-power products may seem simple, but to create a good low-power product, especially achieving ultra-low power, is relatively more challenging. Today, we will discuss the design strategies for low power in RTOS environments. Preface: Programming Mindset The design of embedded products is diverse … Read more
