NAND boot problem after enable SECURE_BOOT in uboot

Using IMX6UL EVK with IMX6UL chip in open mode I can boot from NAND without any problem

but only if CONFIG_SECURE_BOOT is not enabled in uboot.

 

if enable CONFIG_SECURE_BOOT in uboot then booting from NAND no longer works,

I get no output. (Device is in open mode so booting should work even if image is not signed ...)

 

This same uboot image (with CONFIG_SECURE_BOOT) boots just fine when loaded via USB ...

 

Have also tried burning the signed uboot image to NAND and still nothing on the output.
