Using FreeRTOS on ARMv8-M Microcontrollers
[Also see the page that describes how to set ARM Cortex-M interrupt priorities when using FreeRTOS.] ARM introduced TrustZone to the Cortex-M series of microcontrollers with the ARMv8-M architecture. TrustZone is an optional security extension that enables two security domains within a single processor. Cortex-M cores (including the Cortex-M33 and Cortex-M23) that include TrustZone use […]
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 […]
