Where is the golden copy stored in the device in page 296 and 297 of UG1085?

Jump to solution

Hi experts,

 

I guess this might have two answers?

 

A ) This golden copy of the SHA3 hash for BootRom code(Either PMU or CSU) should be in eFuse or BBRAM

B ) This golden copy of the SHA3 hash ....should be somewhere in PMU or CSU?

 

A or B, or other answer?

 

Cheers,

Zumeng

 

Any updates, please, thanks~

Any updates?

 

The same question for the family key for zcu102?

We have the the following definition for the family key in page 263 of UG1085

"The family key is a constant AES key value hard-coded into the devices"

 

Do you mean we can just ignore where is the family key, because CSU know where is the family key is enough, and

it is not visible for user for security.

 

Cheers,

Zumeng
