Hello,
i am stuck with this, trying to write to flash using pstorage module. Below is my code.
static void pstore_cb_handler(pstorage_handle_t * handle,
uint8_t op_code,
uint32_t result,
uint8_t * p_data,
uint32_t data_len)
{
switch(op_code)
{
case PSTORAGE_ERROR_OP_CODE:
ble_nus_send_string( &m_nus, (uint8_t *)"PS general Error.", strlen("PS general Error.."));
break;
case PSTORAGE_STORE_OP_CODE:
if (result == NRF_SUCCESS)
{
// Store operation successful.
ble_nus_send_string( &m_nus, p_data, data_len);
ble_nus_send_string( &m_nus, (uint8_t *)"STORE Operation Done.", strlen("STORE Operation Done."));
}
else
{
// Store operation failed.
ble_nus_send_string( &m_nus, p_data, data_len);
ble_nus_send_string( &m_nus, (uint8_t *)"STORE Operation FAILED.", strlen("STORE Operation FAILED."));
}
break;
case PSTORAGE_CLEAR_OP_CODE:
if (result == NRF_SUCCESS)
{
// Store operation successful.
ble_nus_send_string( &m_nus, p_data, data_len);
ble_nus_send_string( &m_nus, (uint8_t *)"CLEAR Operation Done.", strlen("CLEAR Operation Done."));
}
else
{
// Store operation failed.
}
// Source memory can now be reused or freed.
break;
break;
case PSTORAGE_LOAD_OP_CODE:
if (result == NRF_SUCCESS)
{
// Store operation successful.
ble_nus_send_string( &m_nus, p_data, data_len);
ble_nus_send_string( &m_nus, (uint8_t *)"LOAD Operation Done.", strlen("LOAD Operation Done."));
}
else
{
// Store operation failed.
}
// Source memory can now be reused or freed.
break;
}
}
static bool pstorage_init_routine( void ){
uint32_t retval;
retval = pstorage_init();
if(retval == NRF_SUCCESS)
{
// Module initialization successful.
}
else
{
// Initialization failed, take action.
ps_error_case = PS_INIT_FAILED;
return false;
}
param.block_size = 0x0040;
param.block_count = 1;
param.cb = pstore_cb_handler;
retval = pstorage_register(¶m, &handle);
if (retval == NRF_SUCCESS)
{
// Registration successful.
pstorage_error_occured = false;
}
else
{
// Failed to register, take corrective action.
ps_error_case = PS_REGISTRATION_FAILED;
pstorage_error_occured = true;
return false;
}
retval = pstorage_block_identifier_get(&base_handle, 0, &block_handle);
if (retval == NRF_SUCCESS)
{
// Get Block Identifier successful.
pstorage_error_occured = false;
}
else
{
// Failed to get block id, take corrective action.
ps_error_case = PS_ID_BLOCK_GET_FAILED;
pstorage_error_occured = true;
return false;
}
return true;
}
- So, having done the above, what i do is i always call the pstorage_init_routine() routine before calling pstorage_store().
Then after what is do is this below to store data.
un_g_retval = pstorage_clear(&base_handle, 64);
if( un_g_retval == NRF_SUCCESS ){
pstorage_error_occured = false;
}
else{
pstorage_error_occured = true;
ps_error_case = PS_CLEAR_BLOCK_FAILED;
return;
}
app_store_data[0] = 'A'; //1
app_store_data[1] = 'n'; //2
app_store_data[2] = 'n'; //3
app_store_data[3] = 'i';; //4
un_g_retval = pstorage_store(&block_handle, app_store_data, 4, 0);
if (un_g_retval == NRF_SUCCESS)
{
pstorage_error_occured = true;
ps_error_case = PS_DATA_WRITE_SUCCESS;
return;
}
else
{
pstorage_error_occured = true;
ps_error_case = PS_DATA_WRITE_FAILED;
}
But what i am facing is, data is not been written and i do not get any error in return.
How i am confirming this, by reading data back. And i read back 0xff from the same. Yes, i have not placed delays anywhere because the event so happened in my application does not read back data immediately after writting. So what i believe is the nrf gets plenty of time after pstorage_store() routine is called.
So what is wrong with my code. Please help me out with it. If this question is duplicate, please direct me to the resolved question.
Thank you.
