As long as you do not have the 'disable mass erase' bit set, you always can erase it to unsecure it, see <A href="https://mcuoneclipse.com/2012/11/04/how-not-to-secure-my-microcontroller/" title="https://mcuoneclipse.com/2012/11/04/how-not-to-secure-my-microcontroller/">https://mcuoneclipse.com/2012/11/04/how-not-to-secure-my-microcontroller/</A>&nbsp; and <A href="https://mcuoneclipse.com/2014/06/22/preventing-reverse-engineering-enabling-flash-security/" title="https://mcuoneclipse.com/2014/06/22/preventing-reverse-engineering-enabling-flash-security/">https://mcuoneclipse.com/2014/06/22/preventing-reverse-engineering-enabling-flash-security/</A> .</P><P></P><P>I hope this helps,</P><P>Erich</P></BODY></HTML> Fri, 19 Aug 2016 05:54:20 GMT https://community.nxp.com/t5/Kinetis-Microcontrollers/Device-is-secure-problem/m-p/540696#M33117 BlackNight 2016-08-19T05:54:20Z Re: Device is secure problem https://community.nxp.com/t5/Kinetis-Microcontrollers/Device-is-secure-problem/m-p/540697#M33118 <HTML><HEAD></HEAD><BODY><P>Thank you Mr.Erich.
