The bootloader will erase the existing application to make room for the update image (single bank) if there's not enough free flash to perform a dual bank update.

It is falling back in dfu mode.

This is happening only when updating BL.

When I updated APP, it worked fine.

Sorry, I misread the question then, I thought you were attempting to upgrade from SDK 15 to SDK 17 through DFU. Thanks for clarifying.

[quote user=""]application is not getting started after that. how to debug this ?[/quote]

First thing I would check is if the device falls back to DFU mode or not (i.e. see if it advertises or not). Next you may try to start a debug session with the bootloader or application project to try figure out if execution gets stuck somewhere or if it's simply entering an endless boot loop.

Hi,

I am not updating BL developed in SDK 15. I am updating only BL.

I have flashed SD + APP + BL developed in SDK 17. And tring to update only BL developed in SDK 17.

The same has done with SDK 15 which is working (mentioned to convey procedure that I am following is correct)

But I assume the new app and bootloader based on SDK 17 is using the new Softdevice API? That means you have to update the SD+BL in one go followed by the new application to keep API compatibility at each step of the update.

Thanks for your reply.

I am not updating SD. Only updating BL.

The above question asked was completely different.

I have mentioned same developed in SDK 15 and BL updating is working fine.

This chip does not have enough flash to support a major over the air update from SDK 15 to 17. Please see my answer in your other post for more details: https://devzone.nordicsemi.com/f/nordic-q-a/75098/is-it-possible-to-update-soft-device-in-nrf52810-through-dfu-ota
