I bought FRDM-KL26Z and connected Jlink by cutting SDA (J8 open). It was not successful. LED indicator of Jlink was saying "reset is active on the target". I checked the reset pin of target MCU. It was only 0.9V (/w and /wo Jlink connection). With this, I guess there is something wrong in the board hardware.</P><P>Below is the capture from MCUXpresso IDE.</P><P>Could you advise ?</P><P>Thanks and regards, Daewoong</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="daewoong_0-1612702108689.png" style="width: 400px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/136709iC8682C571547D248/image-size/medium?v=v2&amp;px=400" role="button" title="daewoong_0-1612702108689.png" alt="daewoong_0-1612702108689.png" /></span></P><P>&nbsp;</P><P>&nbsp;</P> Sun, 07 Feb 2021 12:50:40 GMT https://community.nxp.com/t5/Kinetis-Microcontrollers/FRDM-KL26Z-MCU-in-reset-state/m-p/1227575#M59545 daewoong 2021-02-07T12:50:40Z https://community.nxp.com/t5/Kinetis-Microcontrollers/FRDM-KL26Z-MCU-in-reset-state/m-p/1227578#M59546 <P>Hi,</P> <P>Try as follows:</P> <P>1.unplug board&nbsp;</P> <P>2.press "NMI"</P> <P>3.plug-in</P> <P>4.Download</P> <P>&nbsp;</P> Sun, 07 Feb 2021 14:39:40 GMT https://community.nxp.com/t5/Kinetis-Microcontrollers/FRDM-KL26Z-MCU-in-reset-state/m-p/1227578#M59546 nxf58904 2021-02-07T14:39:40Z
