FreeRTOS software system based on Chinese Micro-Control Unit

With the rapid development of the Internet of Things, China’s integrated chip industry has made great progress. A large number of micro-control unit (MCU) enterprises have emerged in China. GigaDevice Semiconductor Inc. develops particularly rapidly. In this paper, GigaDevice’s GD32F450 is used to build a Free Real Time Operating System (FreeRTOS) software system. RTOS can make the programming of embedded systems simpler, more flexible and more efficient. In addition, in case the application partition is destroyed in the process of running, mirror application partitions A and B are used in this system. The bootloader decides to load A or B, and repairs broken partitions automatically if needed. The Two-Level Segregated Fit (TLSF) algorithm is used to optimize the memory management.
