pstorage write process failed with s110

[Satheeshkumar]

hi,

i have tried to write data into flash memory, but i can not, i can read the data from memory.

i had followed your instruction as this link

infocenter.nordicsemi.com/index.jsp

and some other solutions like this following thread

devzone.nordicsemi.com/.../

as per above thread i used 30ms delay aslo.

please any one help me,

note:-

i had used RTC1 interrupt with every 5ms for real time clock to generate current date and time.

This my source code,

uint32_t mem_clear(int block_num, int page_num)
{ 
	uint32_t nReturnValue;
	int i=0;
		nReturnValue = pstorage_block_identifier_get(&block_id,block_num,&block_0_id);
			if (nReturnValue != 0)
				{
					return INTIAL_GET_TYPE_WRONG_3;
				}			
			 for (i=0;i<page_num;i++)
		 		{
				 	nReturnValue = pstorage_clear(&block_0_id,1024);
           block_0_id.block_id += 1024;
					 nrf_delay_ms(30);
					 if (nReturnValue != 0)
					 	{							
					 		return INTIAL_GET_TYPE_WRONG_4;
					 	}	 
				}

}

uint32_t read_from_mem(unsigned char *des,int block_num, int size, int offset)
{ 
	uint32_t nReturnValue;
		nReturnValue = pstorage_block_identifier_get(&block_id,block_num,&block_0_id);
		if(nReturnValue != 0)
			{
				return GET_SYSTEM_PASSWORD_BLOCK_ID_ERR;
			}
		nReturnValue = pstorage_load(&des[0],&block_0_id,size,offset);
		if (nReturnValue !=0 )
			{
				return GET_SYSTEM_PASSWORD_FAIL;
			}
		nrf_delay_us(500);
	return nReturnValue;
}

uint32_t write_from_mem(unsigned char *src,int block_num, int size, int offset)
{
uint32_t nReturnValue;	
nReturnValue = pstorage_block_identifier_get(&block_id,block_num,&block_0_id);
		if(nReturnValue != 0)
			{
				return false;
			}

		nReturnValue = pstorage_store(&block_0_id,&src[0],size,offset);
			nrf_delay_ms(30);
		if (nReturnValue !=0 )
			{
				return false;
			}
			return nReturnValue;

}

static void example_cb_handler(pstorage_handle_t  * handle,uint8_t op_code, uint32_t result, uint8_t * p_data, uint32_t data_len)
{
	if(handle->block_id == pstorage_wait_handle) { pstorage_wait_flag = 0; }  //If we are waiting for this callback, clear the wait flag.
	
	switch(op_code)
		{
			case PSTORAGE_LOAD_OP_CODE:
				 if (result == NRF_SUCCESS)
				 {
						 nrf_delay_ms(1);			 
				 }
				 else
				 {
						 nrf_delay_ms(1);
				 }
				 break;
			case PSTORAGE_STORE_OP_CODE:
				 if (result == NRF_SUCCESS)
				 {
						nrf_delay_ms(1);
				 }
				 else
				 {
						nrf_delay_ms(1);
				 }
				 break;				 
			case PSTORAGE_UPDATE_OP_CODE:
				 if (result == NRF_SUCCESS)
				 {
						nrf_delay_ms(1);
				 }
				 else
				 {
						nrf_delay_ms(1);
				 }
				 break;
			case PSTORAGE_CLEAR_OP_CODE:
				 if (result == NRF_SUCCESS)
				 {
						nrf_delay_ms(1);
				 }
				 else
				 {
						nrf_delay_ms(1);
				 }
				 break;
			case PSTORAGE_ERROR_OP_CODE:
						nrf_delay_ms(1);
				 break;				 
		}			
}

Don't use nrf_delay_ms function, it is block MCU by NOP calls. Not saying it's causing the problem but it is definitely not helping (not speaking about the fact that the if-else construction you use doesn't make any sense, you wait 1ms in all the branches...)

[Satheeshkumar]

thanks for replying, ok i will remove 30ms delay and 1ms delay from cb handler. is there any issue on my code other then delay?

pstorage is a pretty old module. Which SDK you are using?

Have you received NRF_SUCCESS with PSTORAGE_STORE_OP_CODE in example_cb_handler() ?

You can have a look here, there are several examples included: devzone.nordicsemi.com/.../
