连接好了打开studio，打开一个文件出现一个框有两个选项
unable to connect to device.this could be caused by reset line circuitry or
disabled debugWIRE interface.make sure that the reset line is free before continuing
选项是 retry debugwire connectio
use spi to enable debugwire inter
选第一个就重复出现上面这个对话框，选第二个出现failed to re-enter debugwire mode.
make sure the reset line is clear.重试 取消
初学，我想知道导致出现的原因是什么？该怎么解决？
