KDS Debugger Backdoor Key (PEmicro)

I'm using KDS 3.2.0 with a PEmicro multilink and a MK22FN512 MCU.

 

How do I set up the debugger to use the backdoor access key to unsecure the device without a mass erase? Is there a command I can pass in or a setting i'm missing in KDS?

 

 

Thanks,

Hello Matt,

The P&E multilink doesn't support backdoor key function to unsecure.

About the detail answer , you can also check this thread :

And About the use the kientis unsecrity with backdoor , i recommend you refer to this doc :

Alice,

No, I can use the backdoor, I just wanted a way for PEMicro debugger to be able to use the backdoor key to unsecure the device without a mass erase. I do not see anything about the backdoor key in the KDS debugger settings. I know USBDM has an option to use the backdoor key in their standalone programmer.
