Hi there,

not sure if I understood your issue. But maybe you want to take a look at Nordic's dev academy, they have a full chapter on it.

If your question is only regarding the use of an external flash as a swap partition, you really just need to add your flash to partition manager through your devicetree and be sure you have your external flash enabled:

/ {
	chosen {
		nordic,pm-ext-flash = &mx25r32;
	};
};

At least this worked for me.
