您好！

我正在开发基于"slaa721 MSP430FRBoot -主存储器引导加载程序"的引导加载程序。

该文档在 第2.2.3章中指出、在  FRAM 器件中、所有中断都可以被重新编程、并且提供的脚本为我生成了以下.cmd 代码：

    // App reset from _App_Reset_Vector
    RESET                   : origin = 0xf3fe, length = 0x0002
}

但是、我的应用程序似乎无法调用任何 ISR。

一旦我将位置更改为默认值 ：0xFFA2 - 0xFFFE、一切都可以再次正常工作。

MSP430FR23x_Datasheet 文档、第6.3章还规定 IV 必须在0xFF80 - 0xFFFF 范围内。

我缺少什么吗？
