I am using iMX8M Mini .
I haven't found any references to possibility of automatically signing bootloaders and images by Yocto for HAB secure Boot.
But there are manual steps to get offsets and other data from images just build and feed CST tool with them to produce signed images.
Are there Yocto layers implementing this automatically ?
Perhaps not easy but possible, something like this would be very very useful if NXP could incorporate
Hello Antonio Santagiuliana,
The Linux BSP for i.MX does not have recipes that allow for automation of this process and I haven’t seen any similar recipes on the Yocto Project layers outside of our BSP either. This because the process requires several steps that will depend on your configuration and are not easy to automate. Although you may create your own recipes or scripts to automate as much as possible, this is not a trivial task.
My apologies for the inconvenience.
