Simple Multicore Core to Core Communication Using FreeRTOS message buffers [The STM32H745I demo in the FreeRTOS download provides a worked example of the control buffer scheme described below.] In this post I describe how to implement a basic and light weight core to core communication scheme using FreeRTOS Message Buffers, which are lockless circular buffers that can pass data packets of varying sizes from a […]Read more…

Ensuring the Memory Safety of FreeRTOS Part 1 FreeRTOS is a real-time operating system designed for resource-constrained devices, including devices in the Internet of Things (IoT). Because these devices are resource-constrained, they do not provide all the hardware mechanisms richer operating systems utilize to protect the system from external adversaries. On such small devices, security depends on simpler memory protection and execution privilege level hardware, […]Read more…
