Multiple secure boot

    Dear sirs,

our idea is to save several boot images in Flash (FlexSPI NOR) and to start one or the other under certain conditions.

This project is working fine, however, we're wondering if it is possible to make these boot images safe.

So, the question is whether it is possible to save in Flash (and run as XIP) different boot images with different security (as example one for each image).

hello,

What about "different security"? If for different Key it is possiable. It will can't if for secure encryption boot it is not possiable. One may refer to the information as the link.URL:.

    Hi fangfang‌,

it seems that NXP-MCUBootUtility is a great tool.

However, it requires image_enc.zip file and it's not possible access to it outside of China.

We're wondering if you can upload it somewhere else.
