4 Generate Secure Images
1. Use the following command to sign all images from <meta_build> and validate the signed image:
seccools.py secimage –m <meta_build> -p <chipset> -o <output_dir> -sa
Store the signed images in <output_dir>. If <output_dir> is not given, the default location would be
“<Secimage_dir>\secimage_output”.
In this case, the directory is “common/tools/sectools/secimage_output/8909/”
