Abstract

本申请提供了一种启动引导程序回滚方法、芯片，涉及芯片技术领域，该方法包括：在状态标识为不满足预设条件的情况下，启动只读存储器程序对多个启动引导程序中启动顺序排在第一位的启动引导程序进行校验，在校验通过的情况下，将状态标识调整为满足预设条件；在状态标识为满足预设条件的情况下，对排在第二位的启动引导程序进行校验；目标启动引导程序从两个分区中确定具有活动标识的目标分区；目标启动引导程序确定目标分区中的镜像是否已被成功启动过，如果否，调整排在前两位的启动引导程序的启动顺序，将目标分区切换成两个分区中的另一个分区，将状态标识调整为不满足预设条件，触发芯片重启。本申请能够实现FSBL运行异常时的自动回滚。
