Hi,
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
According to the above attachments, it seems that you already enabled the HAB secure boot of the MCU before, so I'd like to know whether the MCU BootUtility tool retains the corresponding key and SRK table.
Have a great day,t

Hi,
Thanks for your reply.
According to your statement, it seems like the corresponding key and SRK table are missing or overlapped, if yes, it's impossible to sign the flashload or application image as the application note shows.
Have a great day,

Could I use some command like "mass erase"?
Hi,
Thanks for your reply.
1) Could I use some commands like "mass erase"?
-- No, I'm afraid that it's impossible to disable the HAB authentication function via some commands.
Have a great day,

But i didn’t change any parameter, just clicking the "Generate Certificate, SRK" button, why the key changing or missing?
By the way, the application note i can't open, does it has name that i can search?
Hi,
Thanks for your reply.
As mentioned before, you already enabled the HAB secure boot of the MCU, then to enter the Serial Download mode, it's essential to assure the MCUBootUtility retains the corresponding key and SRK table, just as the post shows,
Have a great day,
