CC2340R5: Hard fault when integrating NVS driver (SDK version 8.10.00.55)

Tool/software:

Hello support team,

I am trying to integrate NVS module but after initialization, software ends at hard fault.

As seen below, handle returned by NVS_open is also not NULL.

    Hello Rasikraj, 

    From your implementation, I see that you are setting the index of NVS_open() to be zero directly. Have you configured sysconfig to use the NVS driver with a memory index of zero? 

    If you look at the NVS example projects provided, the index is typically a macro defined when adding an instance of the NVS driver, with the index of NVS_open() being the name of the NVS instance in sysconfig. 

    Thanks, 

    David

    Hello David,

    I considered index to be of value 0 by default.

    However, even when it is referenced from sysconfig (and this one also appears to be of value 0), I still get this hard fault.

    Regards.

    Rasikraj.

    Hello David,

    I have further update-

    I was not calling NVS_close() before and seems this was the issue for hard fault.

    If I call it now, seems no hard fault then.

    but this means, when shall application call NVS_close()? Can it be called e.g. just going before sleep?

    Regards.

    Rasikraj.

    Hello Rasikraj, 

    Glad that you are no longer getting a hard fault.  

    NVS_close() can be called before sleep or when the application is done using the NVS. 

    Regards, 

    David
