Dear all,
I found u-boot patch for generating DEK blob.
=> "[U-Boot] [PATCH v5] imx6: Added DEK blob generator command"
Should this be applied to u-boot of which verison?
If someone is known, please let me know.
Best Regards,
George

Hi George,
This patch was made for u-boot 2015, and it is in upstream process to u-boot's master branch. They will be released in the next u-boot release.
There are multiple ways to get it working, you can apply the patch directly you would need the previous the previous patches, and I don't know which are the ones that it depends on.
Or you can clone our custodian branch "u-boot-imx". This is the easiest way, and it will have the latest changes for u-boot and the imx branch
git clone git://git.denx.de/u-boot-imx.git
Or you can try to backport it to previous versions, but that would require more work.

Hi Raul,
this is used to get an encrypted boot with u-boot, right? Where I can find the documentation for a step to step process?
I'm also interested to get the same for the zImage.
Thanks in advance,
Roberto Fichera.
The documentation and tools (CST) for encrypted boot is not available yet.
Sorry.
Have a great day,
Yuri

Dear Yuri,
Is it Really?
I saw the description of Encrypt/Decrypt in the following documents.
=> cst-2.2/docs/HABCST_UG.pdf (HAB Code-Signing Tool User’s Guide Rev. 2.2 10/2014)
Though there is how to use the following functions into the document explanation, is this the function which cannot be used in CST?
=> 5.2.8 Install Secret Key
=> 5.2.9 Decrypt Data

George
