  • 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 […]

  • 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, […]
