Kinetis KL05 secured ? How to unlock with USBDM ?

Hello everybody, and particularly PGO,

 

I have already posted in Kinetis category on the forum, but no one seems to use the USBDM there ! Here is my problem :

 

I have just bought some KL05 devices from Freescale and try to program them with an USBDM (based on "USBDM_SWD_JS16CWJ.pdf" schematic), but it seems that the devices are secured when they are new.... ?

 

With the standalone ARM programmer published by PGO I get a warning saying that the device is secured ("ARM Programmer - Device is Secured.PNG"), I click "Yes" to mass erase the microcontroller but then it fails ("ARM Programmer - Erasing Failed.PNG").

 

With CodeWarrior 10.4 I get a warning saying that the device is secured ("CodeWarrior - Device is secured.PNG"), I click "Yes" to mass erase the microcontroller but then it fails ("CodeWarrior - Problem occurred.PNG").

 

Do you know how to unlock the KL05 devices ? It will be really great if it is possible to do it with the USBDM... if not, maybe with another tool ... ?

 

I'm using the last USBDM version.

 

Thanks for your feedbacks,

 

Best Regards,

Joel Guittet
