CC2640R2F: Using NVS drivers in ProjectZero

Hello Sean,

Sorry for the vagueness of my initial post. I'll list the steps I took to add NVS to a stock project_zero.

First  I made sure to include the driver, and initialize a handle, attrs, and params objects near the top of project_zero.c

#include <ti/drivers/NVS.h>

// NVS handle, params, and attrs objects
NVS_Handle nvsHandle;
NVS_Attrs regionAttrs;
NVS_Params nvsParams;

Next I added the NVS config structures into the CC2640R2_LAUNCHXL.c file so that I had a region of the flash reserved for NVS

/*
 *  =============================== NVS ===============================
 */
#include <ti/drivers/NVS.h>
#include <ti/drivers/nvs/NVSSPI25X.h>
#include <ti/drivers/nvs/NVSCC26XX.h>

#define NVS_REGIONS_BASE 0x1B000
#define SECTORSIZE       0x1000
#define REGIONSIZE       (SECTORSIZE * 4)
#define VERIFYBUFSIZE    64

static uint8_t verifyBuf[VERIFYBUFSIZE];

/*
 * Reserve flash sectors for NVS driver use by placing an uninitialized byte
 * array at the desired flash address.
 */
#if defined(__TI_COMPILER_VERSION__)

/*
 * Place uninitialized array at NVS_REGIONS_BASE
 */
#pragma LOCATION(flashBuf, NVS_REGIONS_BASE);
#pragma NOINIT(flashBuf);
static char flashBuf[REGIONSIZE];

#elif defined(__IAR_SYSTEMS_ICC__)

/*
 * Place uninitialized array at NVS_REGIONS_BASE
 */
__no_init static char flashBuf[REGIONSIZE] @ NVS_REGIONS_BASE;

#elif defined(__GNUC__)

/*
 * Place the flash buffers in the .nvs section created in the gcc linker file.
 * The .nvs section enforces alignment on a sector boundary but may
 * be placed anywhere in flash memory.  If desired the .nvs section can be set
 * to a fixed address by changing the following in the gcc linker file:
 *
 * .nvs (FIXED_FLASH_ADDR) (NOLOAD) : AT (FIXED_FLASH_ADDR) {
 *      *(.nvs)
 * } > REGION_TEXT
 */
__attribute__ ((section (".nvs")))
static char flashBuf[REGIONSIZE];

#endif

/* Allocate objects for NVS and NVS SPI */
NVSCC26XX_Object nvsCC26xxObjects[1];
NVSSPI25X_Object nvsSPI25XObjects[1];

/* Hardware attributes for NVS */
const NVSCC26XX_HWAttrs nvsCC26xxHWAttrs[1] = {
    {
        .regionBase = (void *)flashBuf,
        .regionSize = REGIONSIZE,
    },
};

/* Hardware attributes for NVS SPI */
const NVSSPI25X_HWAttrs nvsSPI25XHWAttrs[1] = {
    {
        .regionBaseOffset = 0,
        .regionSize = REGIONSIZE,
        .sectorSize = SECTORSIZE,
        .verifyBuf = verifyBuf,
        .verifyBufSize = VERIFYBUFSIZE,
        .spiHandle = NULL,
        .spiIndex = 0,
        .spiBitRate = 4000000,
        .spiCsnGpioIndex = CC2640R2_LAUNCHXL_GPIO_SPI_FLASH_CS,
    },
};

/* NVS Region index 0 and 1 refer to NVS and NVS SPI respectively */
const NVS_Config NVS_config[CC2640R2_LAUNCHXL_NVSCOUNT] = {
    {
        .fxnTablePtr = &NVSCC26XX_fxnTable,
        .object = &nvsCC26xxObjects[0],
        .hwAttrs = &nvsCC26xxHWAttrs[0],
    },
    {
        .fxnTablePtr = &NVSSPI25X_fxnTable,
        .object = &nvsSPI25XObjects[0],
        .hwAttrs = &nvsSPI25XHWAttrs[0],
    },
};

const uint_least8_t NVS_count = CC2640R2_LAUNCHXL_NVSCOUNT;

I also made sure to add the define statements for the NVS region name mapping in Board.h

#define Board_NVS0              CC2640R2_LAUNCHXL_NVSCC26XX0
#define Board_NVS1              CC2640R2_LAUNCHXL_NVSSPI25X0

After adding this code I have no problems with building or debugging, but adding NVS_init() into the ProjectZero_init() function causes my device to not advertise at all. This setup for the NVS is the same as what I used in my empty project, at it also seems to be the same in the stock nvs example project. Let me know if this is enough information to help.

Hi,

I'm also facing the same issue. How to add FEATURE_OAD in the stack project's preprocessor symbols. I had done as shown in above image but still its hanging.

Hi Sean,

I had attached the debugger but i cant find anything, After receiving data i'm storing in to NVS and updating to advertisement data (Local Name) and it starts the advertising the updated Local Name but the scan response data is disappeared (shown in screenshots).
