我用KL25开发板遇到了一个问题:我连接板上的USBDM口时电源灯不亮,我用万用表测量了下板上只有2.2V下载程序的时候也下载不了,我尝试了 Flash Programmmer -ARM 解锁 但是在解锁的时候还是不成功。---------------------------
USBDM - Target Connection Failure
---------------------------
Connection with the target has failed.
Please cycle power to the target.
Retry connection?
---------------------------
是(Y) 否(N)
---------------------------
---------------------------
Programming Error
---------------------------
Programming of the target flash failed!
Reason: BDM has no connection to target
---------------------------

FRDM开发板都板载OpenSDA调试器,可以正常解锁的。
