最近做一个stm32的板子，但是老是下载不进程序

最近做了一个stm32的小项目，但是不知道为什么老是下载不进程序，下载程序的时候老是提示“Could not stop Cortex-M device! Please check the JTAG cable”，点完确定后，出现另一个提示”Error: Flash Download failed - Target DLL has been cancelled“.而且JLINK还一直闪红灯，不知道为什么。

以上就是编译后的信息。原理图已用附件形式上传了！还望哪位大神能够帮忙解惑，都忙活三天了，百度上的方法也不好使！

这问题没遇到过，是不是编译软件的某些地方需要设置，比如芯片选型

检查NRST复位线连好了没有

最后的 DEGUG 里边要设置，添加flash 容量的。

这个在下载之前就添加了，但是还是不能用，不知道为什么

是不是数字的大小端没有设置好，看提示内容一直都是这个！

检查一下复位线的连接。

你这个并没有参照有关文件来画的吧 JTAG这个地方，9脚有没有问题呢。启动方式有没有问题。
