将程序烧写至外部FLASH后,发现并不能启动起来,链接JTAG后检查发现程序一直在boot28.inc中循环,并没有跳至main函数,这是什么原因

你好,从外部flash启动的话相应的启动地址等等也需要更改,不知道你对程序有做过相应修改吗?
你好,你是通过哪个外设外扩flash的?对应的boot mode pin有没有修改?以及,cmd文件具体是如何修改的?
我是直接用zone7,外扩的flash,从外部flash启动应该不需要修改pin脚吧?

目前看不是程序没跑起来 而是进不去中断,在主程序内的程序都是正常运行的,但是中断的程序就是进不去,但若是连上仿真器,全速运行,又是没问题的。
这个是哪不对了
