Hello,
I'm trying to get verified-boot working using u-boot 2016.03 on an imx6.
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.
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
