Hi, I used the pstorage example mentioned here and got it to work to an extent. A snippet of my code is :
retval = pstorage_init();
if(retval != NRF_SUCCESS)
{
// nrf_gpio_pin_set(PSTORAGE_ERROR_LED_PIN_NO);
}
param.block_size = 128; //Select a block size of 800 bytes
param.block_count = 16; //Select 50 blocks, total of 40 pages (~40 kbytes). Each page is 1024 bytes....
param.cb = example_cb_handler; //Set the pstorage callback handler
retval = pstorage_register(¶m, &master_handle);
if (retval != NRF_SUCCESS)
{
//nrf_gpio_pin_set(PSTORAGE_ERROR_LED_PIN_NO);
}
//Get block identifiers
pstorage_block_identifier_get(&master_handle, 0, &block_0_handle);
pstorage_block_identifier_get(&master_handle, 1, &block_1_handle);
pstorage_block_identifier_get(&master_handle, 2, &block_2_handle);

Using the code above, I'm able to clear up to 40 pages of data and can write/read but but I have an issue. I have cleared 40kb, however if I change the param.block_size to anything more than 128, or the param.block_count to anything more than 16, the wait flag remains set so my handler is never called. If I remove the while loop connected to the handler, the data written is 0. This issue restricts me to 2048 bytes or 2 pages but I obviously need to use 40. I tried using different values over 128 for param.block_size and over 16 for param.block_count but all combinations resulted in the same problem. Is there any issue that could be causing this?? And how do I fix it??? Thanks for any help :)
