Not easily, it is in protected storage.
For details, see the Amazon u-boot source code, start with the implementation of "Erase All" command.
What you can do is copy the image running in memory.
Which is what "Erase All" copies to the protected area of flash.
Yes, u-boot is the bootloader used in the Amazon builds.
You need to be more clear **which** copy of u-boot you are writing about (there are two, the first that runs and bist, which runs on command).

What do you mean by: "modify something cool" ?
And why do you need to work with the binary image rather than build from the Amazon posted source code?

Note: You should be able to find posts here from people who **have** re-built u-boot with added features.
