最近调试程序的时候老是出现Full Chip Erase Failed! 用的是J-link 上网查找了解决办法 比如芯片解锁 试过了还是不行，换了芯片前几次可以下载 大概5次以后就不行了 我用的是STM32F207 求指教
把BOOT0/BOOT1都置1以后显示是这样的：
Connecting ...
- Connected successfully
- Unsecure chip ...
- Chip unsecured successfully
- Erasing affected sectors ...
- ERROR: PC of target system has unexpected value after blank checking. (PC = 0xE09BE096)!
