I am a freshman in using this FRDM-KL46Z board and KDS ide.

And I just followed the getting started page step by step in FRDM-KL46Z|Freedom Development Platform|Kinetis MCU|NXP .

But when it comes to run the hello_world demo on the borad, a error occured and I tried everthing but can not slove it.

The problem is connecting OpenSDA. The ide can recognize the OpenSDA on USB1.(I disconnect and connect the usb for several times and the refresh button can recognize). Although I try all the BDM_SPEED in the list , the problem is also occured.

This is my device manager cut in Windows.

The openSDA drive is working normally. (I also tried to install the drive again and 9600 baud or 115200 baud for test but failed)

I sincerely hope someone can help me slove this problem. Thanks!
