Device is secure problem

[yusupkhan]

Dear All,

Sometime we try to program newly assembled board using the Multilink we get this error inside CodeWarrior:

"Device is secure. Erase to unsecure?"

We are using MKL16. Some boards are working fine and some boards are showing error("Device is secure. Erase to unsecure?").

How to recover from this problem?

Matter is very urgent. Guide us.

Hi Yusup,

That message shows up as well if you connect to the wrong board/device, see https://mcuoneclipse.com/2012/05/28/device-is-secure/ .

Did you accidentially secure your device? As long as you do not have the 'disable mass erase' bit set, you always can erase it to unsecure it, see https://mcuoneclipse.com/2012/11/04/how-not-to-secure-my-microcontroller/  and https://mcuoneclipse.com/2014/06/22/preventing-reverse-engineering-enabling-flash-security/ .

I hope this helps,

Erich
