"nrf_shd_ble_enable" function error code 4(no memeory for operation)

[hariss]

Board was created using nrf 52832.  The program is being created using S132 in .sdk 14.2.0

Copy and use the contents of the " ble_app_beacon " from the sample furnace code.

In the " nrf_sdh_ble_enable " function used in " ble_stack_init ", Returns error code 4 " NRF_ERROR_NO_ MEM ".

The trace shows a change in the value of the " p_app_ram_start " variable in the " sd_ble_enable " function. The entered memory has an address of " 0x20001368 " and the variable value appears as " 0x200023a0 ".

Can I get some advice on this?

The source below is :

//main.c

static void ble_stack_init(void)
{
    ret_code_t err_code;

    err_code = nrf_sdh_enable_request();
    APP_ERROR_CHECK(err_code);

    // Configure the BLE stack using the default settings.
    // Fetch the start address of the application RAM.
    uint32_t ram_start = 0;
    err_code = nrf_sdh_ble_default_cfg_set(APP_BLE_CONN_CFG_TAG, &ram_start);
    APP_ERROR_CHECK(err_code);

    // Enable BLE stack.
    err_code = nrf_sdh_ble_enable(&ram_start);    //return error 4(NRF_ERROR_NO_MEM"
    APP_ERROR_CHECK(err_code);
}

//nrf_sdh_ble.c

ret_code_t nrf_sdh_ble_enable(uint32_t * const p_app_ram_start)
{
    // Start of RAM, obtained from linker symbol.
    uint32_t const app_ram_start_link = *p_app_ram_start;

    NRF_LOG_DEBUG("RAM starts at 0x%x", app_ram_start_link);

    //input value = 0x20001368, *p_app_ram_start = 0x200023a0, app_ram_start_link = 0x20001368
    ret_code_t ret_code = sd_ble_enable(p_app_ram_start);
    if (*p_app_ram_start != app_ram_start_link)
    {
        NRF_LOG_WARNING("RAM starts at 0x%x, can be adjusted to 0x%x.",
        app_ram_start_link, *p_app_ram_start);

        NRF_LOG_WARNING("RAM size can be adjusted to 0x%x.",
        ram_end_address_get() - (*p_app_ram_start));
     }

     if (ret_code != NRF_SUCCESS)
     {
         NRF_LOG_ERROR("sd_ble_enable() returned %s.", nrf_strerror_get(ret_code));
     }

     return ret_code;
}

Hi Hariss,

In Segger Embedded Studio:

• Right click the project -> "Edit Options.."

• "Select "Common"

• Select "Linker" then go into "Section Placement Macros"

 

• Then change the RAM_Start and RAM_Size
