摘要: 本文介绍了一种基于Cortex-M内核的MCU自动化测试方法,该方法依托V93000型自动测试系统(ATE),通过SWD接口向待测的MCU烧写不同的程序,并开展相应的功能测试。此方法有效解决了MCU筛选测试过程中,程序需要在线重复配置加载的难题,实现了测试全程无需外部人工干预,所有程序的重复配置、加载与测试验证环节均由ATE自动控制完成。应用该方法可优化MCU芯片筛选环节的测试验证流程,显著提升了MCU测试验证的整体效率。

Abstract: This paper presents an automated testing method for MCUs based on the Cortex-M core. This method utilizes the V93000 automatic test equipment (ATE) to burn different programs into the MCU under test via the SWD interface, followed by corresponding functional test. It solves the program of repeated online configuration and loading of programs during MCU screening and testing, that is, no external manual intervention is required throughout the MCU testing process, and the repeated program configuration, loading and test verification are all controlled by the ATE. The application of this method optimizes the test and verification flow in the MCU chip screening process and greatly improves the efficiency of MCU test and verification.

Key words: MCU, testing, Cortex-M core
