i.MX6 UL Manufacturing-Protection authentication

michalhojsik — Fri, 09 Mar 2018 12:34:57 GMT

Hi.

Is there any application note describing the use of the "Manufacturing-protection chip-authentication process" on i.MX6 UL as described in section 6.9.9 of the Security Reference Manual for the i.MX 6UltraLite Applications Processor, Rev. C, 09/2015?

I couldn't find any information about it except those in the Security Reference Manual.

Regards,

Michal

Hello Michal Hojsik,

There is not an App Note or similar document showing the use of the Manufacturing Protection for the i.MX6UL. The closest I was able to find is a patch for the i.MX7 U-boot to support this Manufacturing Protection. Perhaps it can help.

I hope this helps!
