IMXRT106x bootloader

Dear sirs,


I read an paragraph in processor reference manual which says:


"The ROM bootloader provides an API for the user application to boot from a new updated application safely after In-Application Programming (IAP) or re-enter serial downloader mode for image update. See more details in the next section."


Then, it is explained how to send ROM into boot mode using API: "runBootloader (&arg);"


One part of the "arg" is boot image selection (0, 1, 2 or 3). Can someone please explain to me what does this image selection refer to? Is there a way to store 4 different images to flash memory, and this is the way to tell ROM which one of them to boot after reset? If yes, where can I find information about this feature?


Than you,
