BLE and flash write problem

[air]

Hello,

I'm using nrf51822/s130/sdk12.1.0. Before adding BLE code there's no problem in writing inner flash. In main I just added below ble_app_uart codes(not modified).

1. ble_stack_init();
2. gap_params_init();
3. services_init();
4. advertising_init();
5. conn_params_init();

• S130 writed already.
• I use flash area : 2K Bytes area from 0x30000(page 192).

After that reset occurs when writing inner flash. I don't know why. I have to use BLE. How should I do?

thanks,

I add my code.

static void eraseFlashPage(uint32_t * page_address) { // Turn on flash erase enable and wait until the NVMC is ready: NRF_NVMC->CONFIG = (NVMC_CONFIG_WEN_Een << NVMC_CONFIG_WEN_Pos);

while (NRF_NVMC->READY == NVMC_READY_READY_Busy)
{
	// Do nothing.
}

// Erase page:
NRF_NVMC->ERASEPAGE = (uint32_t)page_address;

while (NRF_NVMC->READY == NVMC_READY_READY_Busy)
{
	// Do nothing.
}

// Turn off flash erase enable and wait until the NVMC is ready:
NRF_NVMC->CONFIG = (NVMC_CONFIG_WEN_Ren << NVMC_CONFIG_WEN_Pos);

while (NRF_NVMC->READY == NVMC_READY_READY_Busy)
{
	// Do nothing.
}

}

static void writeFlashPage(uint32_t * address, uint8_t value[]) { uint16_t i;

// Turn on flash write enable and wait until the NVMC is ready:
NRF_NVMC->CONFIG = (NVMC_CONFIG_WEN_Wen << NVMC_CONFIG_WEN_Pos);

while (NRF_NVMC->READY == NVMC_READY_READY_Busy)
{
	// Do nothing.
}

for(i=0; i<PAGE_PARAMETER_SIZE; i++)
{
	*(address + i) = value[i];
}

while (NRF_NVMC->READY == NVMC_READY_READY_Busy)
{
	// Do nothing.
}

// Turn off flash write enable and wait until the NVMC is ready:
NRF_NVMC->CONFIG = (NVMC_CONFIG_WEN_Ren << NVMC_CONFIG_WEN_Pos);

while (NRF_NVMC->READY == NVMC_READY_READY_Busy)
{
	// Do nothing.
}

}
