mfgtool + secure boot

We are in the process of enabling high assurance boot on sabresd boards and in the process, we have updated the uboot for supporting hab and signed the uboot image for flashing on the device.

We used mfgtool for flashing and it worked fine until we updated and signed the uboot. After updating uboot, flashing by mfgtool, the board doesn't bootup either with signed uboot image nor the unsigned uboot image. Is there any configuration change that has to be done in the mfgtool to support uboot modifications or do we have to rebuild the mfgtool src for making the secure uboot to work.
