SDK 9.0.0 S130 softdevice + Flash write

Question

Hi. I try to fusion 's130_nrf51_1.0.0_softdevice' and 'flash write'. I checked flash write. but when i implement flash write with s130 softdevice, it is not working. If i remove the flash_page_erase(); and flash_word_write();, it is working.

uint8_t flash_data[200]={0};

static void flash_read() { uint32_t * addr; uint32_t pg_size; uint32_t pg_num;

pg_size = NRF_FICR->CODEPAGESIZE;
pg_num  = NRF_FICR->CODESIZE - 1;  // Use last page in flash

	addr = (uint32_t *)(pg_size * pg_num);

	printf("%x\r\n", addr);
	for(int i=0;i<20;i++)
{
	addr++;
	flash_data[i] = (uint8_t)*addr;
	printf("%d\r\n", flash_data[i]);
}printf("\r\n");

}

void uart_error_handle(app_uart_evt_t * p_event) { if (p_event->evt_type == APP_UART_COMMUNICATION_ERROR) { APP_ERROR_HANDLER(p_event->data.error_communication); } else if (p_event->evt_type == APP_UART_FIFO_ERROR) { APP_ERROR_HANDLER(p_event->data.error_code); } }

Why not ? softdevice and flashwrite aren't use it in together? Please help me ..
