It's also still there in SDK 17. Should be fixed because it is confusing.

Hello,

Any news here ? It seems that the call in main.c to nrf_bootloader_app_start() is still present in SDK 15.3.0, released in feb. 2019.

Thanks.

Hi,

[quote userid="64696" url="~/f/nordic-q-a/40993/how-does-the-bootloader-load-the-application-in-sdk-15"] how does the application get launched from the bootloader, from nrf_bootloader_init() or from nrf_bootloader_app_start()?[/quote]

The app is launched using nrf_bootloader_app_start() inside the nrf_bootloader_init() function. This behavior is new in SDK 15.x

[quote userid="64696" url="~/f/nordic-q-a/40993/how-does-the-bootloader-load-the-application-in-sdk-15"]If nrf_bootloader_init() is responsible for starting the application, should the call to nrf_bootloader_app_start() be removed?[/quote]

Yes, I think it should be removed. I did some quick tests here, and everything worked fine after I removed it. I have reported this as a bug internally.
