Hi List Our project already several years develop for Marvell Armada 3720 board

Recently we decided to implement verified boot. I modified uboot configuration to support FIT image format and verify signature kernel . I compiled uboot and added public key to u-boot.bin I also created signed kernel image and ensured with fit_check_signed it indeed signed. The problem is that Marvell required to use ATF tools and A3700 utils to produce flash image. I applied same command to ATF to make flash image as we used before for non-verified before. ATF made flash image with no glitch, After transferring resulting flash to board, u-boot continues to boot non-signed kernel and iminfo command reports error “unknown image format” on the loaded signed kernel, i.e. it does not recognize FIT partition.

Can anyone help me ASAP? Regards LEV
