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:

icf文件使用路径:工程右键/options/linker
2.确认App没问题后,bootloader中跳转前,关闭所有初始化的外设,关闭所有开启的中断

1.因为APP修改icf重新设置了地址。在这种情况下,直接仿真实验没有问题。我修改icf ROM地址为0x08000 0000,直接下载不通过bootloader也没问题。
2.关外设和中断我试试(我看到ST官网程序貌似并没有关外设和中断的操作)
2、向量地址的修改
评分

我确认了下boot,没有用到中断。外设开了如下:
// Enable GPIOA, GPIOC and USART1 clock
RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA | RCC_APB2Periph_GPIOC
| RCC_APB2Periph_USART1, ENABLE);
// Enable USART2 clock
RCC_APB1PeriphClockCmd(RCC_APB1Periph_USART2, ENABLE);
试了下,关了这几个外设后还是不行。
1.工程配置你是指icf这个文件吗? 我修改的已经和boot的跳转地址一样了,都是#define ApplicationAddress 0x8002000
2.向量地址是指哪个文件,在哪修改?是指NVIC_SetVectorTable( NVIC_VectTab_FLASH, 0x0 );这个吗,如果是的话,#define NVIC_VectTab_FLASH ((u32)0x08002000),也重定义了
IAR7.6
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
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
错误的icf文件是哪来的?
