其中bootloader程序占据sector0~sector1

app1占据sector2~sector8

app2占据sector9~sector15

bootloader运行后检查app2是否有有效的程序代码：如果有则擦除app1区域，并将app2代码拷贝至app1区，然后擦除app2区域，最后跳转至app1运行；如果app2没有有效代码，则跳转至app1运行

CCS项目采用TI ROM提供的FlashAPI代码，项目中包含的库文件为：FlashAPI_F28002x_FPU32_ROM_EABI.lib

操作flash的关键代码如下：

    }
}

调用 Upgrade_EraseSectorOfApp2()函数，擦除Sector9后，在擦除sector10时程序进入ESTOP0

程序跟踪可以看到，调用的Fapi_issueAsynCommand 函数位于 0x3f8ec8

请问擦除后崩溃的原因可能是什么？

还有，如何将TI ROM中的FlashAPI代码放在RAM中执行？

补充一下：

擦除FLASH时，有时候擦除第2个Sector时崩溃，有时擦除第3个Sector时崩溃

同样的代码，之前还有全部擦除成功的情况。

还补充一下，当前测试出问题的工程是实际工程项目的代码加入了bootloader功能。

如果用另外一个简单的测试App程序，则擦除过程没有问题。

2个app工程所用到的擦除代码都是一模一样的，2个App代码均运行于App1区域
