dek blob in linux

_andev_ — Thu, 25 Jun 2015 13:40:06 GMT

Hi,

I've been using the dek_blob command in the u-boot 2015.04. I would like to know if there is

some tool to replicate the dek_blob uboot command but in linux. I would like to be able

to do a binary blob from a key in order to integrate all the board setup process in the

MFG tools.

I've found the caam_blob_gen example from imx6 platform SDK but I'm not able to

compile it, no yocto integrated and the recommended toolchain from sourcery codebench

lite is not yet available! Any SDK update planned?

Thanks!

Looks like there is no Linux tool, providing “dek_blob” (uboot) functionality.

As for SDK example, I hope the following helps

“Build the key blob generation utility with the Platform SDK”

https://community.freescale.com/docs/DOC-105304

Have a great day,
Yuri

Hi Yuri,

I don't have access to the link you've set. But the Platform SDK is built with a toolchain from sourcery, but this toolchain

is no free anymore. See the README.pdf from the Platform SDK package and try to find the Sourcery CodeBench Lite 2012.09-‐63

Another problem is that the SDK generated must be executed as a all, you can't get only the key blob generation utility and

run it in your linux image...

It's a shame don't have this feature in a command line utility in order to automatize the crypted uboot deployment with MFG tools...

Thanks, but the platform SDK is not the solution for the other points I've set...

I've been able to get the toolchain other way and generate the platform SDK, that's the reason

I know that the platform SDK key blob generation utility is not useful for me
