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

See this post, it's for nRF54, but the same methods apply to nRF91 as well.

Hi,
is that enough to write

CONFIG_TFM_PARTITION_PLATFORM=yin prj.conf and callsecure_read_word(intptr_t ptr)uint32_t
As mentioned in the post I linked to, you would also need to modify the tfm_read_ranges.h

This is the APPROTECT register.
Could you explain what you are trying to achieve ?

Hello Sigurd.
I was using 2.7.0 and moved to 2.9.0 because in the site somewhere (I will look for this quote later and attach) it was written it was easier to read ucir without modifying tfm_read_ranges.h
My client wants to save some data unique for every board in production.
They must be read only.
They must be programmed using nrfjprog as I mentioned before

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