tms320f280049 烧录程序运行问题

你好：

   我使用官网例程flashapi_ex1_program_autoecc，在CCS中debug程序到launchxl f280049c demo板中，程序可以运行并调试，并已确定程序烧录到flash中。当我把demo板断电重新开启时，程序无法运行

Green Deng：

你好，这本来就是个操作flash的例程，你是怎么判断程序没有运行的呢？

Carl Li：

回复 Green Deng:

我在程序中加入LED5灯亮的代码，在第一次debug时，灯是亮的，当我重启demo板时灯没有亮。我用uniflash查看flash memory，看到代码已烧录到flash中

Susan Yang：

回复 Carl Li:

您是不是将LED的代码写在了 Example_CallFlashAPI();之后？

测试代码如下，可以断电重新上电后闪烁

你好：
你给的例程我试了，是可以的。但是我现在想把我的代码放在bank1中运行，修改了cmd文件就把入口地址从0x080000修改为0x090000，测试结果没有闪烁。不知道是不是我配置有问题，还是入口地址不能修改？
谢谢！
