imx8mmevk - Enabling the secure boot support in U-Boot - Unable to find defconfig & Kconfig files

Hello Team,

Am trying to implement and verify secure boot on imx8mmevk.

with reference to i.MX8M family Secure Boot guide using HABv4, we need to enable secure boot support in U-Boot by doing two tasks.

  • Defconfig: CONFIG_IMX_HAB=y
  • Kconfig: ARM architecture -> Support i.MX HAB features

Unfortunately am unable to find those files in my build-env.

Currently we are using yocto project for building images.

- I looked under dir /meta-imx/meta-bsp/conf/machine for editing machine file. It didn't worked? What am I missing here?

Hello,

  It is needed to add "CONFIG_IMX_HAB=y" to Your defconfig file  (imx8mm_evk_defconfig).

Regards,
Yuri.
