RE: I want to perform firmware updates from an SD card for firmware created with the nRF5 SDK.

[quote user=""](1) Can firmware updates be performed with MCU Boot even if the firmware is created not with nRF Connect SDK but with nRF5 SDK?[/quote]

No, that will not work with the SoftDevice (assuming youare making a Bluetooth product).

[quote user=""](2) How do you calculate the positions (addresses?) of image_1, primary slot, and secondary slot, as mentioned in the thread above?[/quote]

We do not have any example of using an SDK card a slot 1, but this is perhaps a generic question. Generally, the secondary slot needs to be as large as the primary slot. As it needs to hold the application as well. You can see that it always is in the SDK examples, and in the nRF Connect SDK, these slots are automatically calulcatd by the partiton manager. None of this is relevant for a nRF5 applicatin, though.
