应该是在工程配置里面,有一项是起始地址。我没有IAR,你找一下配置中的。应该是在MCU这一项。 ...
IAR options/linker是有配置起始地址的选项,我已经设置了。现在的感觉所有的设置都正确,但不运行,只有在iap程序中跳转至应用程序前初始化一个引脚才能正常启动,这就比较奇怪了 最好还是要找到原因,这个不是解决问题的办法。楼主弄一个最简单的工程,只有串口打印,bootloder不要开启任何中断。测试一下。看一下是不是开启了其他的中断,我们也用了很长时间的bootloder,也没发生类似的问题。 安 发表于 2018-2-7 14:54

我知道这样是不行的,目前我的工程仅翻转IO电平,已经是最简单了。没有别的思路可以进一步测试 问题解决。
所用的icf有问题,未初始化一部分stack。正确的icf文件如下:

错误的icf文件是哪来的? IARoption->linker->edit项里面的vector table和memory regions设置正确。
NVIC_SetVectorTable( NVIC_VectTab_FLASH, 0x0 );
这个API宏不要改,只更改第二个参数,偏移量
