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
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
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.
