贴回来一百多片板（MCU是新的），其中有一块板试了各种方法都解不开（MKL25），后为想了想，估计是人品问题
 
 
KL系列锁的情况比较少，有可能还有一种原因是在第一次下载的时候时序不稳定，误擦写了芯片内部security那部分的内存造成了锁定，不过这个是很偶然了，有的时候到最后真的是拼人品，呵呵

这个是我的错误信息，有空给我看看啊。
感觉是没有连接上芯片，至于原因就不知道了。
不知道理解对不对啊

你用的那款芯片？如果使用Jlink的话，可以尝试一下按住Reset脚，然后点击下载按钮，会弹出解锁窗口~

KL25, 按住Reset脚，没有出现解锁窗口啊。

楼主你好，我用的是jlink，K60，调试过程中锁定，后用Jflash-ARM解锁，重新烧写当时出错的程序时继续锁定，又用你说的按住RESET同时download方法解锁，但是就是这个程序一直这样：进入debug后提示***JLink Error: Can not read register 15 (R15), while cpu is running,后续好多这样的提示好多寄存器不能读
这个程序之前是能够正常烧写的，虽然运行起来确实不是我要的结果，其他之前能够正常运行的程序都是能正常调试下载的，楼主你能帮我解释下哪些原因会造成这种结果吗?谢谢！
哦，还有，我用的是KEIL

那种情况应该是没有正确进入调试模式，你可以判断一下是不是我上面提到的第五种原因。还有一个也可能是你程序的问题，对0x400~0x40F地址内存进行了读写，这个你可以通过编译生成的.map文件里面的内存分配查看一下~

谢谢！我还没确定原因，不过我把程序重新复制并编译通过后就能下载了，好奇怪的说...

晕，好吧，呵呵，那是不是工程设置的问题？不过可以了就好，恭喜~

好文章，谢谢！

能够下载后我又调试了下发现程序中确实有访问保留地址的部分，改正后没再出现过这个问题啦。哈哈 谢谢！
