I guess there's something wrong in the function. The BCW can be changed back to 0 only by next reprogramming, it's definitely not done by MCU itself.&nbsp;</P> <P>Regards,</P> <P>Lukas</P> Tue, 08 Jul 2025 10:30:58 GMT lukaszadrapa 2025-07-08T10:30:58Z https://community.nxp.com/t5/S32K/HSE-Secure-Boot/m-p/2128548#M50579 <P>Hi all:</P><P>I would like to ask a question to you.</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="ask.png" style="width: 999px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/346125i35DCD5BB11943EDD/image-size/large?v=v2&amp;px=999" role="button" title="ask.png" alt="ask.png" /></span></P><P>After I configured BOOT_SEQ = 1 using function <EM><STRONG>HseMid_SecureBoot_EnableSeq</STRONG></EM>(as shown in the figure above), and then powered on the device again, when I read the chip memory, I found that BOOT_SEQ was not set to 1.</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Temple_0-1751617259071.png" style="width: 400px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/346126i361B1F13020CB6DB/image-size/medium?v=v2&amp;px=400" role="button" title="Temple_0-1751617259071.png" alt="Temple_0-1751617259071.png" /></span></P><P>How to keep BOOT_SEQ as 1 and make sure that my secure boot will get start？</P><P>Thank you for your reading.</P><P>&nbsp;</P> Fri, 04 Jul 2025 08:27:07 GMT https://community.nxp.com/t5/S32K/HSE-Secure-Boot/m-p/2128548#M50579 Temple 2025-07-04T08:27:07Z https://community.nxp.com/t5/S32K/HSE-Secure-Boot/m-p/2130080#M50672 <P>Hi&nbsp;<a href="https://community.nxp.com/t5/user/viewprofilepage/user-id/251650">@Temple</a>&nbsp;</P> <P>Does function&nbsp;HseMid_SecureBoot_EnableSeq really update Boot Configuration Word?
