Hi All, I successfully completed activity of High assurance boot as per steps mentioned in below link https://variwiki.com/index.php?title=High_Assurance_Boot&release=RELEASE_DUNFELL_V1.2_VAR-SOM-MX7 Now I want to create automate all steps mentioned in above link using yocto. First I started with U-boot, and I enabled SECURE option in mx7dvar_som_defconfig but I got following error

cp: cannot stat '/home/VARI_YOCTO_DUNFELL/var-fslc-yocto2/build_fb/tmp/work/imx7_var_som-fslc-linux-gnueabi/u-boot-variscite/1.0-r0/git/mx7dvar_som_defconfig/u-boot.img': No such file or directory

When i manually compiled kernel u-boot-ivt.img is created instead of u-boot.img. And cp didn't get this file in that folder. What are changes required u-boot recipes so that instead of u-boot.img it will copy u-boot-ivt.img

@dpatil89 There is no reference from NXP or Variscite to automate secure boot for imx7. If you want to impliment it yourself, you can use meta-variscite-hab as a reference, which supports Variscite's imx8/8x/8m family of SoMs.
