SDK12.3 use fs_erase and fs_store

[Mr.Wu]

I am using SDK12.3 and the Flash Storage module to store some data in Flash. I frequently need to update some of these data basing on received commands.

When I use "fs_erase", it has been cycling at "power_manage ();"

fs_callback_flag = 1;	        
ret = fs_erase(&fs_config, fs_config.p_start_addr, NUM_PAGES, NULL);
    	if (ret != FS_SUCCESS)
    	{
    		bsp_indication_set(BSP_INDICATE_FATAL_ERROR);
    	}
    	while(fs_callback_flag == 1)
    	{
    		power_manage();
    	}
    
    
        static void fs_evt_handler(fs_evt_t const * const evt, fs_ret_t result)
    {
    	if (result != FS_SUCCESS)
    	{
    		bsp_indication_set(BSP_INDICATE_USER_STATE_1);
    	}
    	else
    	{
    		NRF_LOG_INFO("fstorage command successfully completed\n\r");
    		fs_callback_flag = 0;
    	}
    }

if i commented out

while(fs_callback_flag == 1)
        {
            power_manage();
        }

this is Complete code

	NRF_LOG_INFO("Erasing a flash page at address 0x%X\r\n", (uint32_t)fs_config.p_start_addr);
//	fs_callback_flag = 1;																																				
	ret = fs_erase(&fs_config, fs_config.p_start_addr, NUM_PAGES, NULL);												
	if (ret != FS_SUCCESS)
	{
		bsp_indication_set(BSP_INDICATE_FATAL_ERROR);
	}
//	while(fs_callback_flag == 1)
//	{
//		power_manage();
//	}
	for(uint8_t i=0; i<4; i++)
	{
		data[i] |= (p_data[i*4+0] << 24);
		data[i] |= (p_data[i*4+1] << 16);
		data[i] |= (p_data[i*4+2] << 8);
		data[i] |= (p_data[i*4+3] << 0);
		NRF_LOG_INFO("Writing data (0x%X) to address 0x%X\r\n\r\n", data[i], (uint32_t)fs_config.p_start_addr + (i*4));
//		fs_callback_flag = 1;
		ret = fs_store(&fs_config, fs_config.p_start_addr + i, &data[i], 1, fs_evt_handler);      					
		if (ret != FS_SUCCESS)
		{
			bsp_indication_set(BSP_INDICATE_USER_STATE_1);
		}
//		while(fs_callback_flag == 1)
//		{
//			power_manage();
//		}
	}
	
	for(int i=0; i<NUM_PAGES_SN; i++)
	{
		flash_data[i] = *(fs_config.p_start_addr + i);
		NRF_LOG_INFO("Reading from flash address 0x%X (hex):0x%X\r\n\r\n", (uint32_t)fs_config.p_start_addr + (i*4), flash_data[i]);
	}

log print show：The write data and the read data are not the same

Have you made sure you put fs_sys_event_handler(sys_evt); inside sys_evt_dispatch() ?

You can have a look at an example here: github.com/.../fstorage_example_simple

[Mr.Wu]

I am sure，

    err_code = softdevice_sys_evt_handler_set(sys_evt_dispatch);
APP_ERROR_CHECK(err_code);

static void sys_evt_dispatch(uint32_t sys_evt)
{
	fs_sys_event_handler(sys_evt);
	ble_advertising_on_sys_evt(sys_evt);
}

[Mr.Wu]

My code is the reference to this link

[Hung Bui]

If you simply test the example in the link , would it work ?
