Just confirming that I can close this case. Seems like you and Vidar sorted it out in another case of yours: RE: program crashes on nvs sample

Best regards,

Simon

Simon,

I'm pretty sure this isn't what I need since it's reading raw flash instead of a register. I'll reach out to Vidar directly.

Hi Keith

Vidar uploaded an example project (and the necessary changes) in his reply with the NVS functions nvs_read() and nvs_write(). SInce the project was made for NCS 2.1.1, some changes will likely be necessary for NCS 3.1.1, but the general idea of enabling NVS in the .conf and calling the functions in the main.c file should be the same.

Best regards,

Simon

Hi Simonr,

Have you been able to find an answer to my Question?

Thank you

Hi Simonr,

I should be able to use the UICR.CUSTOMER[] register the Vidar references in that ticket. I was able to write and read from that register using nrfjprog on the command line. However, I can't figure out how to read that register in my C program. Is there an example of that, where it is clear how to specify the register address? thank you

Hi Keith

Please check out this ticket where my colleague Vidar explains how to add NVS to your project. Let me know if you run into any further issues.

Best regards,

Simon
