Testing imx6 CAAM and secure booting using HAB

[andreasindoni]

Hi Freescale Support Team,

In Imx6 series processors, I know that the CAAM (in software) is a kernel driver, I want to use it in userspace with openssl.

I have read the documentations https://community.freescale.com/docs/DOC-95700, and  I found that you have to install the module cryptodev to communicate from userspace (with openssl) to kernel space (with CAAM).

I have some questions, I suppose that enabled the CAAM, I installed the module cryptodev, I installed openssl with the engine cryptodev, in this case:

• how do I check if everything works?
• how do I access on settings of secure boot using HAB (you must be done from uboot) ?

Thanks,

Andrea

  As for HAB, please use “i.MX_6_Linux_High_Assurance_Boot_(HAB)_User's_Guide.pdf”

and app note AN4581 "Secure Boot on i.MX50, i.MX53, and i.MX 6 Series using HABv4."
