I am using MK26FN2M0VLQ18 in LQFP 144. The problem is when the power is disconnected and reconnected, sometimes the microcontroller does not start, it stays in a state that I do not know. This case only occurs when I disconnect and the voltage is 1.6-1.7 and I connect power quickly. I think it has to be a problem with the microcontroller reset. The power is 3.3V. I can reproduce the error because we have a backup battery, when the battery is between 1.6-1.7V we connect power and sometimes the microcontroller does not start. I am using Kinetis Design Studio 3 IDE, KSDK 1.3.0 and Processor Expert Software. I have activated the LVD What happens?</SPAN></PRE></PRE></DIV><DIV class=""><PRE class="" data-placeholder="" dir="ltr" style="text-align: left;"></PRE></DIV></BODY></HTML> Fri, 20 Sep 2019 12:00:01 GMT https://community.nxp.com/t5/Kinetis-Microcontrollers/Problem-with-the-Power-on-reset/m-p/953169#M54806 fernandogarcia 2019-09-20T12:00:01Z Re: Problem with the Power on reset https://community.nxp.com/t5/Kinetis-Microcontrollers/Problem-with-the-Power-on-reset/m-p/953170#M54807 <HTML><HEAD></HEAD><BODY><P>Maybe the K26 stays in the EZPort mode which usually is the default?</P><P>Check <A class="link-titled" href="https://mcuoneclipse.com/2016/12/22/disabling-ezport-on-nxp-kinetis-to-solve-power-on-issues/" title="https://mcuoneclipse.com/2016/12/22/disabling-ezport-on-nxp-kinetis-to-solve-power-on-issues/">Disabling EzPort on NXP Kinetis to Solve Power-On Issues | MCU on Eclipse</A>&nbsp;</P><P></P><P>I hope this helps,</P><P>Erich</P></BODY></HTML> Sat, 21 Sep 2019 07:36:49 GMT https://community.nxp.com/t5/Kinetis-Microcontrollers/Problem-with-the-Power-on-reset/m-p/953170#M54807 ErichStyger 2019-09-21T07:36:49Z Re: Problem with the Power on reset https://community.nxp.com/t5/Kinetis-Microcontrollers/Problem-with-the-Power-on-reset/m-p/953171#M54808 <HTML><HEAD></HEAD><BODY><PRE class="" data-placeholder="Traducción" dir="ltr" style="text-align: left;"><SPAN lang="en">thanks Erich.
