Writing to the flash during the on air run time!!

[Ahmed Gadallah]

Hi guys,

I am new to Nordic and I am using the evaluation kit "pca10001".

I have managed to run the LED BUTTON example which was declared in application note "nAN-36"

Now, I am trying to write to the flash via the soft device APIs like:

1- sd_flash_page_erase(uint32_t page_number) 2- sd_flash_write(uint32_t * const p_dst, uint32_t const * const p_src, uint32_t size)

For sorrow, it doesn't work!!

I have tried to debug the problem but it seems that, the processor halts or may be waiting for something!!

here you are the code that I have used as an application:

---

/***********************************************************************************************************************/ /********************************************Defines****************************************************************/ #define FLASH_START_PAGE 255 // The page that I would like to start writing at. #define FLASH_PROG_START_ADD ((uint32_t *const)(FLASH_START_PAGE * 1024U))

/***********************************************************************************************************************/ /*****************************************Functions**********************************************************/

/**@brief Function for flash write on air. */ static void flash_write(uint32_t *const p_dst, uint32_t const *const p_src, uint32_t size ) { uint32_t err_code;

err_code = sd_flash_write(p_dst, p_src, size);

APP_ERROR_CHECK(err_code);

} /***********************************************************************************************/ /***************Main Application/

/**@brief Function for application main entry. */ int main(void) {

uint32_t data[] = {0x0000, 0x1111, 0x2222, 0x3333};
uint32_t    err_code = 0;
uint32_t *  	p_evt_id;
	
// Initialize
leds_init();
timers_init();
gpiote_init();
buttons_init();
ble_stack_init();
scheduler_init();    
gap_params_init();
services_init();
advertising_init();
conn_params_init();
sec_params_init();

// Start execution
timers_start();
advertising_start();

err_code = sd_flash_page_erase((uint32_t)FLASH_START_PAGE);

if( NRF_SUCCESS == err_code ) {

	flash_write(FLASH_PROG_START_ADD, data, 4);
	
  }
	
else
 {
        // error erasing
            nrf_gpio_pin_set(LED_1);
 }
	
	
// Enter main loop
for (;;)
{
    app_sched_execute();
    power_manage();
}

}

/**

Need your advice.

Thanks in advance.
