This technical note shows how to fix lock this OTP area on BORA systems running BSP versions older than [[BELK/BXELK software components#BELK 4.1.2|BELK/BXELK-4.1.2]]
=== ConfigID programming ===

It is possibile to execute these operations only using the devel versions of u-boot with the following commands:
In older BSP, due to a u-boot limitation, this OTP area is not ''really'' locked and therefore it should be possible to overwrite its value, with possible identification errors during updates.
Starting from the BELK/BXELK-4.1.2 release this issue have has been solved.
== Lock OTP area ==
It is suggested to update the systems running ''BSP releases'' ''older thenthan'' BELK 4.1.2 performing the following steps:
