pstorage reading other values than writing

[Patriko]

Hi!

Maybe I'm doing something wrong (very possible), but for example, when I want to store array of 3 uint8_t values I use:

uint8_t dataToStore[3];
dataToStore[0] = 11;
dataToStore[1] = 22;
dataToStore[2] = 33;

retval = pstorage_store(&block_handle, dataToStore, 3 , 0);
	if (retval == NRF_SUCCESS)
	{
			// Store successfully requested. Wait for operation result.
	}
	else
	{
			// Failed to request store, take corrective action.
	}

and when I want to read it from the memory to variable I use:

   retval = pstorage_block_identifier_get(&persistant_memory_handle, 0, &block_handle);
	if (retval == NRF_SUCCESS)
	{
		uint8_t           dest_data[3];
		 //Request to read 3 bytes from block at an offset of 0 bytes.
		retval = pstorage_load(dest_data, &block_handle, 3, 0);
		if (retval == NRF_SUCCESS)
		{
                         // here dest_data should be: 11, 22, 33 but it gets different values.
		}
		else
		{
				// Failed to load, take corrective action.
		}

Received value is always different than stored. What can be the reason?

Read this:

Block size and offset in load, store and update shall be a multiple of word size (4 bytes).
