CCS连接测试如下The controller cannot monitor the value on the EMU[1] pin.
The controller cannot control the timing on output pins.

CCS调试错误如下CORTEX_M4_0: Error connecting to the target: (Error -2062 @ 0x0) Unable to halt device. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 7.0.100.0)
用MDK能扫描到芯片ID。
实在解决不了了？希望哪位有类似经历的大佬给点解决思路，谢谢。

看提示The controller cannot monitor the value on the EMU[1] pin，应该是你画的板子有线没有连接到单片机的引脚，你查查pcb板吧，应该是有没有连线的情况，不行用飞线接起来，试试吧。

项目用开发板很正常呀，撸码的与画板子的分开，撸码的可以先撸起来，画板子的硬件没有问题的时直接换个板 ...

程序是用开发板调的，也画了自己的板子准备用在项目上，结果下不了程序，很尴尬啊。电源电压3.246V，晶振也起振了。

那就要看看你硬件了！最小系统查查看了！

查了，我怀疑是不是芯片FLASh锁了，不能下载程序。
