Hi @Shealtiel ,

  Which secure boot mode you want to use?

  HAB authentication, HAB encryption, or BEE?

  Seems you are using the HAB operation, if this method, I highly recommend you use our SEC tool:

https://www.nxp.com/design/design-center/software/development-software/mcuxpresso-software-and-tools...

  This will help you do the signed operation, it also provides the log, and you can refer to that log to do the correct operation.

  From your log, it report the myBinfile, seems your previous operation have issues.

If you want to use the cmd method, you also can refer to my post:

Wish it helps you!

Best Regards,

Kerry

Hello,

When we create the secure boot image and click on write image button will it burn the fuses with the appropriate configuration??

How can I manage in the second attempt without configuring the fuses?

Thanks,

Hi @Shealtiel ,

  Which mode you want to use? if you are used the unsigned mode, it won't burn the fuse, but, if you choose the BEE, HAB related operation, it will burn the fuse.

 To the secured program, it will help you to burn the related fuse, to the second secure program, it won't burn the fuse anymore, just download the app.

 So, it is totally determined by your usage.

Wish it helps you!

If you still have question about it, please kindly let me know.

If your question is solved, please help to mark the correct answer, just to close this case, thanks.

Any new issues, welcome to create the new case.

Best Regards,
