no GPC问题，无法调试。
我按照GDK7-Startup-new这个PDF步骤。
1：windbg调试器(我安装了19041 sdk，带了windbg)。
2：fastdci文档。
2.1：安装驱动。
2.2：安装NDB，登录。
2.3：复制、解压两个压缩包。
2.4：调试主机与被调试主机成功连接，USB设备正常识别。
2.5：修改保存ndb.cfg文件。
开启调试：选择了DCI OPEN，最终显示以下信息。

我点击中断，显示00:10:12#JTAG:Unable to perform operation because there are no GPC threads in this domain。如果被调试主机不开机，显示的信息都是一样的，我是哪里没设置对吗。
屏幕输出如下：

OPENIPC里也是有信息的。被调试机器开关机，也是能接受到事件。
