帮我看看这是什么原因没有下载成功？

KEIL刚装上不久，还没有玩熟。出现了Error: Flash Download failed - "Cortex-M3"这个提示，应该找哪里原因呢？

这是编译下载例程WIFI_LINK时出现的。

相关设置：
1、targate

2、debug

3、Utilities

4、下载前与下载后，只有在BOOT拨到低时才出现的串口情况，

我在0X0800C0000那里下载，怎么会提示

Contents mismatch at: 08040000H (Flash=00H Required=07H) !

呢？

我也碰到这个，好像是ZI-data太大了，不知道是不是

问题解决了。整片擦除后就好了。
