sdk12.2 DFU buttonless ble_dfu_init crash

[ypearson]

I'm trying to run the DFU buttonless example however this line crashes the app:

err_code = ble_dfu_init(&m_dfus, &dfus_init);

UPDATE:

Looks like this is causing the crash, which is inside the aforementioned function

nrf_dfu_settings_init();

This file is broken, it needs to be updated from the stock sdk12.2 version.

Thanks for reporting this :) I will report this internally and add it to our known issues list with SDK v12.x.x, found here.
