Reading UICR

Hello,

is it possible to read UICR at address FF8000 from a non secure application for nrf(160.

If yes, can you provide sample code and CONFIG to enable in prj.conf.

Best Regards

  • As I promised, this is a quote from Ask AI.

    You mentioned that since 2.8.0 it is easier to read UICR register in nrf9160
    Yes, that's correct. According to the nRF Connect SDK v2.8.0 Release Notes, there has been an improvement in reading UICR registers for Trusted Firmware-M (TF-M). Specifically:
    • A possibility to read UICR.OTP registers through platform services has been added.
    • The TF-M version has been updated to v2.1.0.
    This change makes it easier to access UICR (User Information Configuration Registers) OTP (One-Time Programmable) registers in the nRF9160.
    This improvement should simplify the process of reading these registers during runtime for applications using the nRF9160.
