IMX8M Mini secure boot

[filipvuko]

Hi everyone,


I'm trying to wrap my head around building yocto image with secure boot for IMX 8M mini. So far researching google has lead me to a lot of 404 links and other dead ends. Can you please provide me with some guidance? 

Thank you

Hi,

You can refer to <10.9 Automated image signing for secure boot in i.MX application processors> from the Linux User Guide: i.MX Linux User's Guide (nxp.com.cn)

What kind of security features are there on imx 8m mini and plus? 

For example:
HABv4?
CAAM? 
etc...
