secure boot imx8mp

Hi all,

We are working on enabling Secure Boot on an i.MX8MP-based device and have made good progress so far. We're using NXP’s Code Signing Tool (CST) version 4.0.0 and following the official NXP Secure Boot guide.

By default, the provided csf_spl.txt and csf_fit.txt configurations use the SRK1, CSF1, and IMG1 keys, which work as expected. However, we want to switch to using SRK2 / CSF2 / IMG2 to sign our flash.bin.

I attempted to modify the CSF configuration files to use SRK2/CSF2/IMG2, but I haven’t been able to get it working correctly.

Could someone please help guide me on the correct configuration for csf_spl.txt and csf_fit.txt to enable signing with SRK2, CSF2, and IMG2?

I’ve attached the NXP guide as well as our current csf_spl.txt and csf_fit.txt files for reference.

Any assistance would be greatly appreciated!

Thank you,
Abhishek
