Dear NXP community,
I try to generate a dek blob on a mentioned wandboard imx6qp processor.
So I've written dek.bin on the SD card with a signed u-boot.
After those commands:
load mmc 0 10800000 dek.bin
dek_blob 0x10800000 0x10801000 128
I receive such an output:

Encapsulating provided DEK to form blob
Allocation of page 0 in partition 1 failed 0x1
My device isn't yet closed.
I've found out that icache and dcache shall be OFF for blob generation.
It didn't help me.
I've found out that the signed u-boot can NOT be singed with:
[Unlock]
Engine = CAAM
Features = RNG
This also didn't help.
I've tried combination with signed SPL(+ signed/not signed u-boot), and without SPL. Nothing works.
I use those sources:
git://git.denx.de/u-boot-imx.git
Do you have any idea, what am I missing here?
Why the dek_blob command cannot instantiate RNG?
Best Regards,
