Hi there,
I have a script in FIT image, I want to verify its signature before running it.
When I run "source" command, it doesn't check the signature, only hash at 1.
images {
...
script {
description = "Script";
data = /incbin/("script.txt");
type = "script";
compression = "none";
hash at 1 {
algo = "crc32";
};
signature {
algo = "sha256,rsa4096";
};
};
}
How to make u-boot verify the script before running it? Is it possible to auto run the script when boot a configuration from a FIT image?
Thank you
Cheers,
Andy
