How to set the EXPORT_CONTROL fuse of i.MX6

[yuuki]

Dear all,

In Booting of i.MX6, an error may occur in CAAM.
This error occurs in RNG.

I attach an error log.

I would like to try it with CAAM disabling.

The following is indicated to the reference manual.
"When CAAM is disabled (i.e. when the EXPORT_CONTROL fuse is blown) then encrypted boot is not available."

I looked for description of EXPORT_CONTROL fuse.
However, I was not able to find this.

Would you teach the address and field of this Fuse?
And would you teach how to have burned this Fuse?

Best Regards,
