What parts of UICR.OPT[] are available?

[loquat]

I work nRF54L15 with NCS311.

I want to save application's parameters on UICR.OPT[].

But it looks like somewhere in OPT is used by the bootloader.

What parts of UICR.OPT[] are available?

Hi,

We are working on reserving a part of UICR.OTP for customers that we guarantee will never be used by Nordic firwmare (like bootlaoders). It is not finalized yet, but I expect it will nok take long. Please see this pull request.

OK.Thanks.

Can I make more space available to users by reducing CONFIG_PM_PARTITION_SIZE_PROVISION?

Hi,

In principle yes, but that will leave less room for bootloader provisioning data. Also, for future proofing I would recommend that you stay within the region that is about to be reserved for customer use as that way you will be guaranteed that there is no potential conflict with future SDK updates.

May I ask what type of data you want to store there as 32 4 byte words words is not enough? Could it be that some of this data could make sense in other locations?

OK.Thanks!!
