Hello,

I'm working on a product where I need to control several peripheral via the same SPI (different chip-select pins).

One of the peripherals is an External Flash device, which we want to control via NVSSPI25X.h driver.

I would like to use the NVS_lock() API to prevent tasks writing to the external flash while the same SPI is busy accessing other peripheral devices.

I could not find where is NVS_lock() implemented, although documented for several SDK releases.

Should I use NVSSPI25X_lock() directly? This routine is implemented in NVSSPI25X.c.
When will NVS_lock() be implemented?

BR,

Amit

Hello Amit,

you can use NVS_lock API and it will call the NVSSPI25X_Lock api since it is directly mapped to the function calls. You can see this in the NVS section of the CC1352P1_LAUNCHXL.c

Hello,

It's trivial that NVS_lock(), provided with a handle to some NVS external flash should call NVSSPI25X_Lock().

Could you please point out to where is NVS_lock() implemented?

It's header is in NVS.h as 'extern', but its implementation is not in NVS.c. When calling NVS_lock() the code fails linking.

Is NVS_lock() implemented inside some library?

Amit

Hello Amit,

If you are using internal memory or the external flash form the board it should be externing it from the device specific drivers. They can be found in the folder nvs.

Hello Amit,

Were you able to find this? C:\ti\simplelink_cc13x2_sdk_2_20_00_71\source\ti\drivers\nvs
