The latest FreeRTOS V11 release includes an interesting feature: a heap protector feature, which can help detect memory corruption early at runtime.

Multi-Core Symmetric Multi-Processing (SMP) with FreeRTOS
Maybe you are using a multi-core device in your projects, but have not tapped into multi-core usage yet? FreeRTOS V11.0 is out, and the big news is that it has finally Symmetric Multi-Processing (SMP) integrated into the mainline. This greatly simplifies FreeRTOS usage, as I finally can use the same RTOS for my SMP targets and boards, and I can easily switch between single-core and multi-core applications.
LittleFS File System with MCU Internal FLASH Memory
In many of my embedded projects I need persistent data or storage for settings. If using an SD card, then FatFS is usually my choice for the file system. But if using an external FLASH memory device, then my preferred choice is usually LittleFS: it is a little fail-safe filesystem, designed for micro-controllers, which I’m using with external flash memory devices.
In the case where there is enough MCU flash, or if there is no external FLASH device available in a design, it can use the MCU internal FLASH as storage storage too. This is the topic of this article:
Added Heap Memory Monitoring and Tracking to FreeRTOS V10.5
We all should know it: dynamic memory usage can be dangerous. There can be memory fragmentation, use-after-free, out-of-memory and memory leaks. While I do prefer static memory allocation for embedded systems, using a dynamic memory allocation in some applications is not avoidable or just makes sense.
In one of my lecture modules we develop a ‘Boulder’ game, where the player has to collect underground diamonds and avoid moving monsters:
I’ll show you have FreeRTOS memory usage can be tracked and monitored.
