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

[jiteshka]

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.
