Loop after fs_store freeze the code

I'm using 51822 QFAC, SDK11 S130 2.0.0.

I'm able to write to flash using fstorage_write() below.  But the problem is whenever I put a for loop after I call fstorage_write(), the code will totally freeze.  If I put the for loop before fstorage_write(), everything is ok. What is problem with this? thanks a lot!

 

void fstorage_write(uint32_t fdata[], uint16_t arraySize, uint8_t const offsetPage )
{
    static uint32_t data[256];
	for(int i=0;i<arraySize;i++){  
		data[i] = fdata[i]; 
	}
    
    fs_erase(&fs_config, (uint32_t)(fs_config.p_start_addr+offsetPage*256), 1); 
 	while(fs_callback_flag == 1)  
 	{ 
    	app_sched_execute();
    	power_manage(); 
	}
	
	fs_store(&fs_config, (uint32_t)(fs_config.p_start_addr+offsetPage*256), data, 256);
	while(fs_callback_flag == 1)  
 	{ 
    	app_sched_execute();
    	power_manage(); 
	}
}

myFunc(){
    fstorage_write(myData, size, page);
    
    for(int i=0;i<size;i++){    <====== a for loop after fstorage_write freeze the code!
        myData[i] =0;
    }
}

Thank you Jorgen for the reply!

It's a hardfault, later I found that it may be related to UART. Since I use UART to print out the values, if I remove printf after fstorage_write(), it looks like working for now. If I put printf with a loop (no matter inside or outside), it just get stuck before the loop.
