1. Error #10413: 指定地址不在已初始化的 section 中

#10413: error specified at 0x86000 does not lie within an initialized section

这个错误表示没有对改地址进行初始化操作，原始cmd文件中是这样定义的：

FLASH_BANK0_SEC6  : origin = 0x086000, length = 0x001000    /* on-chip Flash */

再没有开启ecc功能之前，没有报错，因此这是ECC配置没有成功告诉链接器SEC6是有效的。因此需要再ECC配置中指明FLASH_BANK0_SEC6时ECC要涵盖的区域。对于auto模式，flash数据和ecc地址是自动完成映射的，但是由于我们需要引入错误位，因此改用手动模式，这时就需要再cmd文件中添加ecc的地址，并且在cmd中添加ECC模块的支持算法，修改后的cmd文件如下：

修改之后，如果还是出现这个错误，说明sector6里面没有存入数据，他会认为这个区域没有被使用，所以必须要保证sector6里面被存入了数据。 我将test中的内容存储了一部分在sector6里面

 .text            : >>FLASH_BANK0_SEC0 | FLASH_BANK0_SEC1 | FLASH_BANK0_SEC2 | FLASH_BANK0_SEC3 | FLASH_BANK0_SEC4 | FLASH_BANK0_SEC6,  PAGE = 0, ALIGN(4)

修改完以后，这个问题解决了。

2. 出现错误：C28xx_CPU1: File Loader: Verification failed: Attempted to write past the end of memory at 0x1080000@Program

这个问题说明启用了 ECC，但 .cmd 文件中 ECC 的地址段并没有被程序识别为“有效可写内存区域”。这是因为没有告诉linker，这些段是可以写入的。因此需要在SECTION中添加对ECC区域的映射，告诉它ECC区域可以被使用。并且在cmd文件的最后，添加ECC的算法。

                parity_mask = 0xFC
                mirroring = F021
}

如果还不能解决这个问题，这个时候需要检查自己是否关闭了自动生成ecc的模式。如果没有关闭，两者会产生冲突，也会出现报错。 点击debug位置的黑色倒三角，选择Debug Configurations

在这里一定要注意，选择C28xx_CPU1:

 然后选择界面上的Target——Flash settings，关闭这里的Auto ECC Generation功能：

重新设定以后，上述报错有效解决。

3. 程序运行过程中出现意外中断。由于我在程序中对flash操作的每个阶段设置了提示，我发现程序没有办法正常的运行。这个时候才意识到，我把text段落的一部分存到了sector6里面，但是flash需要再写入数据前进行擦除操作，也就是说在程序运行的过程中，一些有用的数据被删掉了！那程序自然不能正常运行。针对这个问题，我希望通过在sector6中写入一些无用数据，来填充它好让程序认为它被使用了。具体的操作如下：

在cmd文件的section部分指定一个sector6区域的位置：

 my_app_data : > FLASH_BANK0_SEC6, PAGE = 0, ALIGN(4)

 这个操作意味着，my_app_data中的内容只能被放入到SEC6中。然后在主函数中告诉编译器把 myData 的数据放到指定的段 my_app_data 中：

#pragma DATA_SECTION(myData, "my_app_data")

再定义需要写入的数据，这些数据随便写入就行： 

const uint16_t myData[10] = {
    0x1234, 0x5678, 0x9ABC, 0xDEF0,
    0x1357, 0x2468, 0xAAAA, 0x5555,
    0x0F0F, 0xF0F0
};

这里特别要注意需要使用const对数据进行定义。

我最开始写的是 uint16_t myData[10]，然后又出现报错1，说sector6没有被使用。我查了一下，应该是因为编译器 优化掉了这个数组（我后续没用到它）。然后建议我改成volatile，但是会出现：error #10392-D: cannot generate ECC for "my_app_data" in memory range FLASH_BANK0_SEC6; objects may only have load data in this range. 

我查了一下他们的定义，volatile是变量，告诉编译器这些数值会被修改，在烧写是放入data段，在运行的时候装载。编译器不会允许这样的变量存放在ecc区域中。因为flash的数据写入必须进行擦除，每次写入都要进行擦除后才能修改数据，因此把一个可变变量直接写入会出现报错。但是const代表常量，是不会被修改的，就是一个只读变量，所以flash允许它写入。可以把ECC区域理解为‘只读区域’。

通过上述修改，整个代码终于可以正常运行了！！！！
