Hi,

I would like to know a temporary way of provisioning SRKH Register(without blowing the fuses) and executing secured boot.

I am aware of SFP SRKH Mirror Registers being mapped to 0x01E80254 location onwards.

 

Question 1:

If we write to these mirror register will they have any effect on fuse array?

 

 

Question 2:

What is the endian-ness of SRKH Register?

 

 

 

Question 3:

During prototyping, can secured boot functionality be tested without blowing fuses?. If so, how?

 

 

Regards,

Rashmitha
