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;
    	}
    }

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

Is the callback triggered by softdevice event ? I don't think it's a good idea to put a loop inside a interrupt handler (callback) to wait for an event. If the event is at the same priority it won't be able to interrupt the loop.

My suggestion is to set a flag after you erase, and the let the loop inside the main loop to wait for that flag of erasing, then you can continue to do store functions after that.

do you have any example to demo this, "set a flag after you erase, and the let the loop inside the main loop to wait for that flag of erasing, then you can continue to do store functions after that", for me have run into the same question, thanks
