I am building an secure image for doing a secure firmware update using yocto linux. For that I have to use a signing tool. The signing tool cst tool which I downloaded from digi documents shows extract failure when I build using build command bitbake core-image-base. I followed the instruction provided by digi for building secure image. The instructions followed up are - copying the cst-3.1.0.tgz file in to download folder. Modify local.conf file as per digi documents for secure boot.
Please let me know whether I will get a supported cst tool or older versions of the cst tools. Please share the link for downloading older versions of the cst tools.
Please find the attached snap shot.
