i.MX28 HAB Secure Boot Chain

Hi,

 

I was successfully able to use the HAB and the Code Signing Tool to sign and to validate the signature of Eboot on i.MX28.

 

The application note AN4555 indicates that "The same library functions can be called from later boot stages to extend the boot chain past the stage immediately after the Boot ROM", using the HAB API.

 

I am interested in extending the secure boot to the OS  and Application.

 

Are there any additional documentation from Freescale on the details of the HAB API and on how to extend the secure boot chain for i.MX28?

 

Thanks for your time and assistance.

 

Best Regards,

Gary
