Hello,

  In the secure close mode, it is possible to load an image, at least to check it.

But it is not possible to run unsigned image. Boot ROM does not allow to run

unsigned U-boot; further responsibility for verifying and running applications

under U-boot belongs to the U-boot. 

Have a great day,
Yuri
