Thank you.

I did this, but without the struct and addresses in the mdk it is all a little bit hacky. It would be good if this would also be accessible from a non-secure via spm in the future without modifying the nrf-sdk code (like it is already possible for FICR INFO).

For now everything works for me, i just wanted to report the issue so a fix is incorporated in future connect sdk releases.

Hi,

My apologies for this inconvenience! Thank you for reporting this issue in the mdk ficr struct. I will report this internally.

[quote user=""]3. The spm does not allow access to SIPINFO in FICR via spm_request_read(), see https://github.com/nrfconnect/sdk-nrf/blob/main/subsys/spm/secure_services.c#L88 [/quote]

If the range is not per your requirement, I would recommend that you modify this specific file to ensure that you can read the specific area from non-secure region.

Kind regards,

Håkon
