I am assuming you are using NVS_write?

A status of (-4) is NVS_STATUS_INV_OFFSET

This is all documented here:

NVS.h File Reference (ti.com)

I recommend that you use the nvsinternal example as a starting point:

nvsinternal (ti.com)

Hi Siri,

I am using FlashProgram() following is the AP decryption:

https://software-dl.ti.com/simplelink/esd/simplelink_msp432e4_sdk/1.60.00.10/docs/driverlib/msp432e4/html/group__flash__api.html#ga3dca804ebcefe3819eb4178efa4ac294

I don't see error code 4 in this description in this link as well.

Thanks,

Bhasker

I do not understand. You state that you are using the CC1312R7 device, so why are you referring to the simplelink_msp432e4_sdk?

You need to use the simplelink_cc13xx_cc26xx_sdk_

Sorry that was quick google search link, I am using simplelink Sdk only:

FlashProgram() function is defined in following flash.c file, provided by simplelink SDK.

simplelink_cc13x2_26x2_sdk_5_20_00_52_s/source/ti/devices/cc13x2x7_cc26x2x7/driverlib/flash.c

Please note that we do not recommend customers to use driverlib directly. Driverlib is meant to be used by our drivers only, and then you should use the driver.

Please use the example as I linked to as a starting point.
