Hello,
I'm trying to get verified-boot working using u-boot 2016.03 on an imx6.
It would be better to try something more recent, such as 2018.03 instead.
So far I've managed to figure out that I need the following additional config settings: #define CONFIG_DM #define CONFIG_ENABLE_VBOOT #define CONFIG_RSA #define CONFIG_FIT #define CONFIG_OF_CONTROL #define CONFIG_FIT_SIGNATURE #define CONFIG_OF_SEPERATE #define CONFIG_OF_LIBFDT #define CONFIG_FIT_VERBOSE
However, no matter what I do I can't seem to generate u-boot.dtb.
This is expected if your board does not use device tree file in U-Boot.
My understanding is that u-boot automatically generates this u-boot.dtb for the purpose of storing the public key when mkimage signs the fitimage and that this process does not require that I provide a dts file.
However, below are the files that are generated with my current configuration and no u-boot.dtb file is generated.
Additionally, since u-boot produces a u-boot-nodtb.bin, I figured it was reasonable to believe that u-boot.bin contained the device tree however as shown below both u-boot-nodtb.bin and u-boot.bin have an idential hash.
Is there something that I'm missing here? Any advice would be greatly appreciated
Thank you,
Davis

That's the one you need.
If your board does not use device tree you will get a u-boot.imx binary that you can flash into your boot media.
