器件型号：CC2340R5

工具与软件：

团队成员、您好！

我叫 Vatsal Joshi、我将在 CC2340上开发一个基于 BLE 的应用。

由于产品要求,我们需要在 NVS 部分存储一些用户配置(~4KB )。因此、我们已经配置了0x4000 (起始地址：0x7C000至0x8000)的 NVS 部分。

我们已经创建了示例代码,可以在 SNV 中写入4000字节的数据, 只是为了检查我们是否能够在 NVS 中写入4000字节。在向存储器写入虚拟数据时、该器件允许我们在 NVS 部分中写入多达1800字节的数据、但不能写入比 NVS 部分中更多的字节。

当我们尝试写入数据1.8 KB 时,"osal_SNV_write"无法写入并返回错误0x05。

请查看下面随附的同一代码。

#define READ_WRITE_LEN      200
#define WRITE_ITERATION     20
#define COMPARE_LENGHT      5

//Below given function is write dummy data in the memory. Every iteration it will write data of 200 bytes in the memory. So 200*20 = 4000
//#define BLE_NVID_CUST_START             0x100     //This is defined inside "bcomdef.h"
