Everything has been working perfectly so far. We have now encountered the question of what reactions are possible if Secure Boot fails in early stages of the boot process.<BR />More specifically, what reactions are possible if the Boot-ROM cannot successfully authenticate the bootloader? Can the failed authentication of the bootloader be signaled in some way?</P><P>Thanks!</P> Thu, 14 Aug 2025 11:15:26 GMT matthoe 2025-08-14T11:15:26Z https://community.nxp.com/t5/i-MX-Processors/Secure-Boot-HAB-Possible-reaction-on-Bootloader-authentication/m-p/2152329#M240113 <P>Hi,&nbsp;</P><P>we use an i.MX8 processor and implement Secure Boot based on HAB.
