Query on S32K144 CSEc module and secure boot

Hi,

 

I have few queries on CSEc module and secure boot. Can you please help me to understand below queries.

 

Query 1:

 

From below diagram I see PRAM(memory to store secure keys) is of 128 Bytes.

   Is this memory extendible and configurable ?

   What is the maximum number of keys we can store in this area ?

   What is single secure key size in bytes?

Query 2:

To enable secure boot for certain memory region, I know we use BOOT_MAC_KEY_VALUE.

What key should we use if multiple memory regions need to be secured, whether it is same BOOT_MAC_KEY_VALUE ?

 

Query 3:

Once we enable secure boot(FTFC->FCSESTAT->BOK is 1), how to prove the secure boot concept ?, please guide me the steps.

 

Thanks

Mohan
