Sure, I though both are similar and raised in same query. I will raise it separately.

Thank you for your quick inputs. Please let me know your inputs on below query.

In “ble_app_blinky”, as part of wait_for_flash_ready(), I replaced power_manage() to idle_state_handle(). Is this fine. Whether both are same ?

void wait_for_flash_ready(nrf_fstorage_t const * p_fstorage)

{

/* While fstorage is busy, sleep and wait for an event. */

while (nrf_fstorage_is_busy(p_fstorage))

{

idle_state_handle();

//power_manage();

}

I don't know if SES has a setting to always erase the entire chip. Or to include additional sectors in a partial erase. You'll have to search through the options and/or study the documentation.

Or ask Segger: https://forum.segger.com/

Erasing takes a (relatively) long time, and wears out the Flash - so, in general, one would only do this when specifically necessary.

No.

Hi,

1) Also please let me know your inputs on query 2 in my above post.

2) Yes, I am using Segger Embedded Studio.

Only through below steps I am able to erase entire chip. Is this correct way.

a) Target -> Connect J-Link

b) Target -> Erase All.

But in Segger status I am seeing "Erase". Does not this erase entire Flash.

Thanks & Regards

You mean Segger Embedded Studio?

Segger also has a number of other tools for flashing code

Yes, that is normal behaviour.

If you want to do a full chip erase, you have to do that manually - but remember that will also erase the SoftDevice.
