CC2642R-Q1: CC2642 non-volatile memory

Part Number: CC2642R-Q1

Hi Team,

Here're few questions from the customer may need your help:

1) There're about 20K of data stored in non-volatile memory. Is it OK to store so much data?

2) How to check how much memory is being used by the user's own ICALL_malloc allocated memory?

3) In which document is the CC2642 Flash distributed? Include NVS, Bluetooth Protocol Memory Footprint etc.?

Could you help check this case? Thanks.

Best Regards,

Cherry

    The device has 352KB of Flash that should be shared between the non-volatile storage and the binary. So, as long as the binary size is not too large, you can store this amount of data in flash.

    Please refer to the debugging guide and the functiuon ICall_getHeapMgrGetMetrics

    If you are asking about where you can find the source code owning the data stored in NVS, then you cannot really access it as this code is provided as library. I can only tell you the larger part of the NVS flash consumption comes from the GapBondManager.

    If you are asking about details on the data stored, you can refer to the User's Guide.

    I hope this will help,

    Best regards,
