能识别芯片，但是到最后一步下载的时候出错了，弹出下图那个提示框。我的下载模式没选错，芯片我是64K的，选的是128K的，因为列表中看不到64K的，不过我之前选的128K的也没影响。

是不是软件装的有问题，报错但是程序是否下载成功，我下载Cortex-M0+的时候也会报错，试试使用J-Flash下载H ...

用J-Flash我也试过了，还是不行。应该不是MDK下载的问题，我有一块板子成功了，是可以用MDK下载的。下面是J-Flash出错的代码，您看看：

是这样的，我做的这款板子当时没有预留SWD接口，只留了一个串口下载接口，但是串口好像经常有问题，于是我就飞线连在了arm仿真器上了，接线应该没什么问题
