device is secured

[vinkar]

Hello Friends,

I unfortunately managed to secure my device (kl04 chips). I have seen quite a few articles in which it states that the Code Warrior IDE warns the user if he is about to make such an error ( or via the component inspector). I am not using the processor expert so I guess I cannot use the component inspector.

Also, how can I unsecure my chip.

I am using the PE Multilink Universal.

Hello Vinod:

How did you notice your device is secure?

The way to unsecure a Kinetis device is with a Mass Erase. However, if your KL04 is secured, CodeWarrior should ask you to erase it (a message box saying "Device is secure. Erase to unsecure?), and clicking on "Yes" usually solves it. Do you see that message?

If this does not work, try with the "Always mass erase on connect option", in the connection settings, as in the attached picture.
