It has been unsecure. Can you provide some support？</P><P>SREC:</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="ZEROOO_0-1696744147344.png" style="width: 400px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/243976i21A479F652A5C80D/image-size/medium?v=v2&amp;px=400" role="button" title="ZEROOO_0-1696744147344.png" alt="ZEROOO_0-1696744147344.png" /></span></P><P>debugger:</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="ZEROOO_1-1696744196112.png" style="width: 400px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/243977iD3D0BA1D9FBBACB6/image-size/medium?v=v2&amp;px=400" role="button" title="ZEROOO_1-1696744196112.png" alt="ZEROOO_1-1696744196112.png" /></span></P><P>&nbsp;</P> Sun, 08 Oct 2023 05:50:08 GMT https://community.nxp.com/t5/S32K/S32K144-backdoor-problem/m-p/1735258#M27634 ZEROOO 2023-10-08T05:50:08Z https://community.nxp.com/t5/S32K/S32K144-backdoor-problem/m-p/1737107#M27744 <P>In winidea, you need to configure the following two things to modify the security zone correctly.
