Hi ! I'm wondering why the is_hab_enabled function (see arch/arm/imx-common/hab.c) is reading the fuses rather than the OCOTP shadow registers ? During my attempts at secure boot I realized two things: - by default, if secure boot is not enabled, the HAB rom will block any authenticate code - if the secure boot fuse is not burnt, but the shadow register is written by software before calling the HAB entry point, authenticate works fine.
Since the ROM seems to read the shadow register rather than the fuse, why is u-boot doing differently ? Best regards, Vincent _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
