        The ST meta layers and Octavo SDK’s ship with a boot.scr.cmd with an interesting warning to the developer:

        https://github.com/octavosystems/osd32mp1-build-tools/blob/master/files/ssbl/boot.scr.cmd

        I have reviewed the script and of course it runs correctly from a Yocto dunfell build. The configuration changes don’t make any sense and am ready to disregard the warning. I assume the message is for U-Boot loaders that support multiple boards such as “osd32mp1-red” and “osd32mp1-brk” where the board / target is set dynamically. What is ST asking for us to change?

          Carlos,

          I think the warning is more about security rather than functionality. The features in the script can be used to inject malicious code such as a device tree overlay that should not be applied on a production level product. The suggestion is to use hard coded paths in u-boot bootcmd to setup boot.

          Best,
          Neeraj
