I have a question about implementing the secure boot on the imx8m mini evaluation kit (on eMMC).
I'm using the YOCTO BSP imx-4.14.98-2.0.0_ga and I'm able to build an image for the eMMC.
In my deploy folder I can see the bootloader file "imx-boot-imx8mmevk-emmc.bin".
I looked at the documentation to implement secure boot on the imx8:
To sign my bootloader, I have to edit a CSF file and add the addresses/sizes of the different blocks of my bootloader.
The documentation uses the imx-mkimage build log to get these addresses/sizes. In my case I don't have this build log.
Do you know where to find this bootloader build log ?
Also, do I have to manually sign the bootloader image manually every time or can YOCTO do it for me ?
