This process is well integrated in yocto, from what I remember activating the fitimage is relatively easy: - in your machine.conf - declare KERNEL_CLASSES += "kernel-fitimage" and KERNEL_IMAGETYPE = "fitimage" - in your u-boot defconfig (configs/yourboard_defconfig - enable CONFIG_FIT=y - in your config include/configs/your_board.h change the script to boot your fitimage I hope this helps, Regards, Mathieu > -----Message d'origine----- > De : yocto-boun...@yoctoproject.org <yocto-boun...@yoctoproject.org> > De la part de Srinivasan, Raja Envoyé : August 8, 2018 2:51 PM À : > yocto@yoctoproject.org Objet : [yocto] uBoot, kernel and device tree > files > > All > > > > We are using rocko.on variscite var-som-mx6. > > In order to increase the security of our system (during a system > upgrade), we are looking to merge uImage (kernel image) and the device > tree file into 1 file.
