Flash Data Storage read problem

[Shivanand]

I am new to nRF,

Unable to read data using flash data storage example.

When ever i try to read it

throughs error and processor enters into error handler and hangs there indefinitely.

Help will be appreciated.

Thanking You.

We are not mind readers: we don't know what you've done, therefore we can't tell you why or where it's wrong!

Are you familiar with any other microcontroller(s)?

Are you familiar with 'C' programming in general?

Have you started by using the provided examples, studying them, and understanding how they work?

Am aware of c/c++ and microcontroller(s), am sharing code snippet for your reference

void read_config_data(device_config *configuration)

{

    ret_code_t rc;

    fds_record_desc_t desc = {0};

    fds_find_token_t  tok  = {0};

    rc = fds_record_find(CONFIG_FILE, CONFIG_REC_KEY, &desc, &tok);

    if (rc == FDS_SUCCESS)

    {

        /* A config file is in flash. Let's update it. */

        fds_flash_record_t config = {0};

        /* Open the record and read its contents. */

        rc = fds_record_open(&desc, &config);

        APP_ERROR_CHECK(rc);

        /* Copy the configuration from flash into m_cfg. */

        memcpy(&read_config, config.p_data, sizeof(m_cfg));

        /* Close the record when done reading. */

        rc = fds_record_close(&desc);

        APP_ERROR_CHECK(rc);

    }

}

And how does that compare to the examples?

Where does the error occur?

What error is it?

How to properly post source code:
