使用keil5下载STM32H7的程序时报错：

相同的工程下载正点原子的开发板一点问题都没有。
网上搜了一下，有说是复位电路设计有问题，有说是芯片型号对应错误，有说全片擦除一次就好了。以上都试了，查了，都没解决我的问题。
还有说把verify关掉就好了，确实是关掉不报错了，但是程序还是没法正常运行
我使用st官方的软件读取了一下flash内部的数据，发现在报错的位置数据都变成0xff了，而且也不是以sector为单位的，多试了几次出现0xff的位置也不固定，但一段一段长度还挺固定的。
使用st官方软件直接烧写hex文件可以正常运行。但是不行啊，我需要用keil debug程序，还得继续查。
最后发现原因是packs需要更新，正点原子的芯片和我采购的芯片可能不是同一批次，所以会有些不同，而旧版的DFP库的烧写策略影响了正常使用。
但是很坑的是，我在keil内置的packs install里面看不到需要更新
误认为当前是最新版，其实还要去官网下载http://www.keil.com/dd2/Pack/#/eula-container
安装上就好啦~
完成！
