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:

https://www.nxp.com/webapp/Download?colCode=AN5401SW&location=null
See section 4.4 Secure boot and see SW example 4_secure_boot_add_BOOT_MAC_manual.
