Secure Boot Implementation without Secure Access Files

Is there a way to run a secure boot on an S32k board without the secure access files? If so - how would that be accomplished?

Please allow me to directly paste the reply I gave you for Case 00999901 here.

I may not have understood your question. Please correct me if I'm wrong.
It seems you have a misunderstanding about Secure Access Rights.
Once you obtain Secure Access Rights, it doesn't just provide Secure Boot-related materials; it also grants you access to Secure Resources. I suggest you read the Secure Access Rights FAQs for more information.

Based on your description, it seems you have already obtained Secure Access Rights. In that case, you can search for relevant information by clicking Secure on the S32K3 documentation website and entering keywords. For example input boot:

If you do not have Secure Access Rights, you cannot even download RM00286 HSE-B Firmware Reference Manual - V2.7 [RM758227]. S32K3's Secure Boot uses a boot integrity/authenticity verification mechanism based on HSE (Hardware Security Engine). Without this document, it will be very difficult for you to become familiar with HSE.

Regarding Secure Boot, I also recommend you read the discussion here: https://community.nxp.com/t5/S32K/S32K3/td-p/1735306

Advanced secure boot mode is recommended. This mode offers more regions to be checked, so you can configure it to cover both bootloader and application.
Basic secure boot mode can check one region only.

Best Regards,
Robin
