Tool/software:

I'm using CC2340r5 and SDK 8.4

I'm using OAD project ,in this I want to store some 20-30 bytes data in NVS ,given custom_NVS configuration as below

When I build and run only the application, I am able to read and write data correctly.
However, after updating the firmware using uniflash with mcuboot, persistent and application using below address

and also using (SimpleLink Starter app), reading and writing returns junk data.

Kindly let me know if the address I am using is correct or not.

Hi,

If you are defining a new NVS region, please ensure that it does not overlap with any other flash regions on the device. Please add the region to the linker file as this will help catch this. An additional point to consider is that if you only need to store 20-30 bytes, then I would highly recommend leveraging the osal SNV region instead of creating a new region and using an entire sector. The BLE5-Stack already reserves some of the flash for bodning and pairing information. Part of this region is reserved for user information if desired. The following User's Guide section details how to write/read from it:

Best Regards.
