How to put MCUBoot secondary slot in external QSPI Flash on NRF5340-DK?

[jmp246]

Board: NRF5340-DK

NCS: 2.3.0

I want to use the external flash to store mcuboot's secondary slot. I have based my code on the smp_svr sample and configured it for serial.

I was able to uploaded a image and marked pending (test) via mcumgr cli while the app is running.

But mcuboot never accesses the secondary slot to perform the swap. Leaving the slot as always pending.

I was building it configured for serial.

I was able to implement it in NCS 2.1.3

Based on devzone.nordicsemi.com/.../352191

You need to configure the external flash for the MCUboot child image as well.

See how this is done in our (main branch) nrf/tests/modules/mcuboot/external_flash.

I was able to get the example working and integrate it into an existing app thanks.
