nRF52832 two applications in memory after secure buttonless DFU update

[IstvanS]

Hello! Is it normal, that there are 2 applications in memory after secure buttonless DFU update? Please see screenshot of memory map:

I used SDK version 16. Shouldn't the old app have been removed and replaced by the new one?

Thanks!

Yes, in that case it's effectively free, so I think the illustration is fine. If you just added those few lines of clarification to the documentation, it would be perfectly clear.
