最近将一个IAR下的M4的程序移植到M7上，移植之前M4的程序因为没有硬件没有验证过，当修改为所有的参数，编译都正确后仿真时，在下载过程中报了好多的警告——地址数据校验错误，错误如下：
- Thu Jan 24, 2019 07:33:44: Verify error at address 0x000080D1, target byte: 0x40, byte in file: 0x30

然后IAR就报错：
一开始还以为没问题，点击OK继续执行，结果是程序直接跑飞了：
卡在了某个位置。然后问度娘，大概的意思是工程的配置不对，但是试了几个方法都没有凑效。于是自己使用STM32CubeMx新建了一个可以运行的工程，然后比较工程配置，最终发现是因为options->linker->config下的linker configuration file没设置flash的icf文件导致的，见下图：
选择正确的flash的icf后程序运行正常。
