Analysis and Implementation of Migrating Real-Time Embedded Operating System FreeRTOS Kernel Based on S3C44B0 Processor

摘要

Stack overflow is an essential part of FreeRTOS operating system migration problem on S3C44B0 processor. This paper analyzes the structure of FreeRTOS system's real-time kernel and the architecture of S3C44B0 processor, and studies stack structure model on S3C44B0 processor running on FreeRTOS operating system. An execution strategy is described to solve the problem of stack overflow and interrupt error when FreeRTOS system is migrated to S3C44B0 processor. Result perseveres and proves the correctness of migration strategy. The principle and method of migration presented in this paper has practical engineering significance.
