Hello, I have a question about the S32K CSEC module: 1. For each PCBA, the BOOT_MAC_KEY is same or not? 2. How to write the BOOT_MAC_KEY firstly?

Hi,

1. For each PCBA, the BOOT_MAC_KEY is same or not?

- It depends on your needs, it's up to you.

2. How to write the BOOT_MAC_KEY firstly?

- There's an application note AN5401 which describes this in detail:

See section 4.4 Secure boot and see SW example 4_secure_boot_add_BOOT_MAC_manual.
