Da14580自定义板闪动问题的程序

大家好!
我的名字叫凯文。
我有一个自定义板专门设计da14580和da14580的一个devkit-B。当我试着在devkit上调试da14580的闪烁代码时，它成功运行并且led会周期性闪烁。
但是当我调试闪烁的代码到我的自定义板时，usb附近的devkit上的红色led没有打开，而keil上的命令日志显示如下:

* JLink Info: Reset:通过demcr . vc_coreeset重置后暂停核心。
* JLink Info: Reset:通过AIRCR.SYSRESETREQ重置设备。
SP = _RDWORD (0x20000000)
$ = _RDWORD (0x20000004)

然后我试图找到另一种方法，使用智能代码片段在定制板上闪烁代码。当我在smarsnippets中使用jtag模式时，日志显示如附件页1，当我使用uart模式时，日志显示如附件页2。我有点搞不懂“cpu没有停止”的意思。你能为我的问题提供解决方案吗?
是水晶的组装问题吗?
