I'm with a MK22F512xxx12 connected by SWD with a FRDM-K22F. The Mcu is blocked, I cannot debug or erase.
Do you know how to unlock the Mcu?
Thank's, Best Regards
Hello rémi raynaud,
I can recommend you follow these steps, described here Unsecuring the KL25Z Freedom Board | MCU on Eclipse
also it is discussed at Freedom board - "Device is secure. Erase to unsecure?"
If your problem does not appear, please, let me know.
As I recall, this can be accomplished by typing "unlock kinetis" in the J-link command line.
I've tried to "unlock kinetis" (look at the command line in the screenshot, attached to the post) in the J-link command line but it doesn't change...
Thank's for yours answers
Ok, sorry I missed that.
