一、简介

AD14N 以及 AC104N 部分旧版SDK在运行时有概率会死机，经查验发现这部分SDK内置flash（存放代码的flash）的运行时钟上限在80MHz，导致flash会有兼容性问题。解决办法是降低运行时钟上限。

二、涉及的SDK版本

ad140-release_v1.0.4
ad140-release_v1.0.5
ad140-release_v1.0.6
ac104n-release_v1.0.3

三、涉及的开源版本SDK

ad14n-ad15n-release_V1.1.0
ad14n-ad15n-release_V1.2.0
ad14n-ad15n-release_V1.2.1
ad14n-ad15n-release_V1.2.2

四、解决办法

在 app/bsp/cpu/sh54/clock.c 文件中，将内置flash运行时钟限制在60MHz内即可；
