NRF_UICR->CUSTOMER equivalent on nRF53

[Sebastor]

Hi,

I'm porting firmware between nRF52 and nRF53 platforms. What is the equivalent of NRF_UICR-> CUSTOMER on nRF53 to keep data like serial number etc.

Thanks

Hi,

That would be this. Note, that it's only the nRF52832 that has multiple word Customer registers, all other ICs in the nRF52 series and the nRF5340 has a single word Customer register.

Hi,

Yes but it is in the network core. Can I access this data from the app core? I'm going to use Key Management Unit to store customer data.

[Jared]

Is this for storing keys? The peripheral has dedicated registers for this in the UICR? Could you elaborate?

[Sebastor]

I just need to store some customer data (serial number) in UICR, and have access to it from the application core. The solution you provided -> this is available only for the network core, so my idea is to use KMU instead.

Hi,

I see. Yes, you're correct, those registers that I linked earlier is for the network core. I agree, the KMU is probably your best option on the nRF53 series. I should probably have recommended that from the beginning :)
