Reading UICR

[Marbro1965]

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

You can just read the register directly. For example, reading out the first entry in the one time programmable memory (Source of registers):
uint32_t reg_val = *(volatile uint32_t *) 0x00FF8108;

That is at least what I used to be able to do with something like the nRF52840. I don't know if the nRF9160 has extra security measures.

Unfortunately does not work in this way.

Thanks
