IMX95 Processor
Explain about the below screen shots

IMX95 NXP Processor need Cortex-A core image and Cortex-M core image
Explain breif about the Building an image supporting secure boot

For our processor need both Cortex-A core image and Cortex-M core image or only Cortex-A core image ?

Currently i executed successfully only Cortex-A core image?

If your answer is Yes both we need to use ?

Hello,

The App note for the secure boot using AHAB for the i.MX8X is available at the following link: https://www.nxp.com/docs/en/application-note/AN12312.pdf

And you can refer to the security reference manual after request in the following link:

All the information applies as well for iMX95.
