Use the secure boot, but Is it possible to disable the verification for POC purpose.

As per the imx7 secure boot design, Booting is happening using the root of trust. Is there any way that without using verification I can boot up the board? i.e. Just for the POC, i want to run the "secure boot" SDK/software without verification, I will not be using the signed image.So verification is also not required. Is it possible to do that?

Hello,

   i.MX7 board can be booted even if a boot image cannot pass verification 
correctly - when the i.MX7 is not (secure) closed. But it is not possible to run 
unsigned boot image - by boot ROM - if the i.MX7 is closed.
  If the boot image is correctly signed - it can load and run any image.

Regards,
Yuri.

Thank Yuri,

How to set/make the i.MX7 in non-secure mode?

If the boot image is not signed and i.MX7 is not closed (i.e. non-secure mode) then Does the boot-ROM allow the boot image to run?

 By default (fuse configuration of) i.MX7 is in non secure (open) mode.

Yes - If the boot image is not signed and i.MX7 is not closed (i.e. non-secure mode)
then  the boot-ROM allows the boot image to run.
