我按照GDK7-Startup-new这里设置的。具体报错如下： 00:28:23#JTGE:JtagMessageEvent:type=1 dbgportid=Failed to establish target connection. The OS was unable to communicate with the debug hardware. The target may need to be power cycled. Error: (Error: 0x0016000e) 00:28:23#JTGE:JtagMessageEvent:type=2 dbgportid=DCI: Device Gone (Target Power Lost or Cable Unplugged)
