View source for BELK-TN-011: Lock OTP Areas

== Introduction ==
As described on [[ConfigID_management_(BELK/BXELK)|ConfigID management]] page, these information are stored inside a general-purpose OTP area of the SoC.

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 ===
All Bora SOMs are shipped with ConfgID and UniqueID programmed and locked. The OTP lock ensures that nobody can change this data (unattempted code execution, etc).

It is possibile to execute these operations only using the devel versions of u-boot with the following commands:
<pre>
configid som_configid <16 byte code>
configid som_uniqueid <32 byte code>
configid som_lock 0
</pre>
