CC2640R2F: SNV will become zero value after Power off=>Power ON

Part Number: CC2640R2F
Other Parts Discussed in Thread: BLE-STACK

Hi All,

I use SNV to write some parameter, it is work on power on state by write and read function.

but SNV will become zero value after Power off => Power on,

My setting

1. OSAL_SNV = 2

2. #define BLE_NVID_CUST_START 0x80 //!< Start of the Customer's NV IDs

#define BLE_NVID_CUST_END 0x8F //!< End of the Customer's NV IDs

thank you.

Hi Amors,

What version of the SimpleLink CC2640R2 SDK are you using?

How are you reading the SNV?

Did you follow the SNV code example in the BLE-Stack user's guide?

Hi Marie:

1. SDK version: simplelink_cc2640r2_sdk_2_30_00_28

2. Yes, I follow the sample code to use SNV

uint8_t buf[50] = {0xff};

uint8_t status = osal_snv_read(0x81, sizeof(buf),(uint8_t* )buf);
if (status != SUCCESS)
{
osal_snv_write(0x81, sizeof(buf), (uint8 * )buf);
}

but it still wrong after power off=>power on

Hi Amors,

If you upgrade to the newest version of the SDK, do you see the same issue?

Thanks,
Elin
