Hello,
we're using secure boot on imx6ul. Everything works as expected. The only problem is, that I need to reset board when the image verification fails.
I use hab_rvt_authenticate_image() in u-boot to verify loaded firmware image. When the image is broken, or the signature is even missing the board stops, which is actually almost what we want. But we need also the board to reset automatically.
Is there any option how to force the board to reset on an error in HAB in U-Boot?

Hello,
I meant, that the required functionality is not supported by U-boot directly,
customers can implement it themselves as reset via watchdog.

Hello,
It is needed to add such feature as reset at HAB authenticate to U-boot manually.
Please refer to U-boot / Linux BSP documentation how to rebuild U-boot.
Have a great day,
Yuri

Hello,
could you be more specific about the documentation? I went through few pdfs including HAB4_API, i.MX Linux Ref. Manual and HAB CST User Guide but found no clear clue.
Thank You
