I am trying to use the dek_command in the i.MX6UL, but I am getting some errors:

 

=> dek_blob 0x80800000 0x80801000 80

RNG: Instantiation failed with error ffffffff

RNG: Instantiation failed with error ffffffff

RNG: Instantiation failed with error ffffffff

RNG: Instantiation failed with error fffffffd

RNG: Failed to instantiate RNG

RNG instantiation failed

 

Encapsulating provided DEK to form blob

Allocation of page 0 in partition 1 failed 0x1

I add the following U-Boot configuration options:

 

#define CONFIG_SYS_FSL_SEC-COMPAT 4

#define CONFIG_FSL_CAAM

#define CONFIG_CMD_DEKBLOB

#define CONFIG_SYS_FSL_SEC_LE

 

Is the configuration correct? How could I debug/fix those errors?
