iMX6UL U-Boot 2019.04 doesn't boot from flash if not signed

We have ported our module to the new 2019.04 U-boot and have seen that our u-boot will not boot from NAND when SECURE_BOOT is enabled. But it will boot from RAM using uuu tool.

 

Why is it now necessary to sign the U-boot with this new version?

In the previous version we used 2017.03 that was not necessary using the same configuration

 

Is the HAB events checked during boot and if that fails u-boot will not start?

 

Best regards,

Hello,

 

  Please let me know more details about the issue.

1.

   The following U-boot release is used, correct?

uboot-imx - i.MX U-Boot 

 2.

 U-boot configuration:  CONFIG_SECURE_BOOT=y

 i.MX 6UL fuse SEC_CONFIG[1] =0 (open)

 

3.

  Uboot does not boot from NAND and it boots if  CONFIG_SECURE_BOOT=n

Have a great day,

Yuri.
