Hi,

I found it

You can use this https://github.com/nrfconnect/sdk-mcumgr/blob/d9adfe78efd71608b77ac88a5b088723a9fbe6ed/cmd/img_mgmt/include/img_mgmt/img_mgmt.h#L209

In combination with hooks such as CONFIG_MCUMGR_GRP_IMG_UPLOAD_CHECK_HOOK (according to the migration guide https://docs.zephyrproject.org/latest/services/device_mgmt/mcumgr_callbacks.html#migration)

Kind regards,
Andreas

Hi,

[quote user="byte"]that a BT boot load is about to start?[/quote]

It's a bit unclear what you mean with this, could specify what you mean by this some more? To my understanding you're referring to either when you start to swap from MCUboot secondary app slot to MCUboot primary app slot or when you're entering MCUboot to upload the new firmware to MCUboot secondary slot.

Either way, the answer should be the same. It should exist something that you can use to get upload status, so I assume there should exist something that you can use for the purpose you describe. I will get back to you

Kind regards,
Andreas

Thanks, do you know if there is a way to get a callback/notification that a BT boot load is about to start? I'd like a user to be able confirm the process on the device before allowing it to continue.

Hi,

If you've not done so already, I recommend that you have a look at https://academy.nordicsemi.com/courses/nrf-connect-sdk-intermediate/lessons/lesson-8-bootloaders-and-dfu-fota/. This course should point you in the correct direction w.r.t doing DFU for only a single core.

Kind regards,
Andreas
