"Device is secure. Erase to unsecure?" on KL27Z Freedom Board

[Anjali]

I am using KL27Z freedom board. It was working fine before, but suddenly I started getting an error "Device is secure. Erase to unsecure?" and also the controller temperature is too high. Please note that I am using MCU expresso ide. I found one solution to resolve this in eclipse. Any help would be really appreciated.

Regards,

Anjali.

Hi Anjali,

Please check if there is the hardware damage. Normal lock issue will not cause temperature rise too high.

If it's not a hardware issue, you can try the attached guide.
