Verify Failed! JTAG speed: 200 kHz 是不是芯片型号选的不对呢，我记得LPC1114在MDK里边有好多个型号，不行的话就一个一个试吧 擦除和写入操作都已成功，只是校验出错了，楼主换个板子试试，或者象2楼建议的，降低JTAG速度再看一看。 TCK(pin 9)low, but should be high,please check the hardware；
终究是因为lpc1114之前调试时将加密位使能，导致LPC1114不能下载程序，不能调试，也没有运行。
解决方法：
在烧写程序前P01口接GND！然后再下载，调试，OK。 快乐的小娃 发表于 2014-2-17 14:01

楼主是用ISP方式擦除的吗？ 不好意思，之前忘记回复了，已经解决，可能因为下载线太长的原因，降低频率之后，好了~谢谢~
