好东西 顶一个

MDK环境用ULINK2解锁Kinetis K60系列芯片：
对于ULINK2、ULINK-ME 和 ULINKpro 调试器, 你必须保证Options For Target — Debug — Settings选项中 Connect 和 Reset Options 项的设置如以下所示:
        Connect项必须设置为under Reset
        Reset项必须设置为HW RESET
保存设置后，尝试重新下载。存储器将会解锁，应用程序将能下载。
以上是KEIL公布的方法，前提是芯片的DEBUG功能没有被禁用。

友联的开发板怎么样？？？

芯片被锁是因为IAR生成的启动代码覆盖了0x0_0400 -- 0x0_040f地址空间，这块区域是用来加密的。
最新的IAR软件已经改掉了这个BUG，不会再出现这个问题了。
