How to reference PM generated partitions from device tree?

[Jeffrey Haynes]

I'm trying to set up a FAT FS on external flash on the 5340 DK.  It looks like the correct way to do this is to include a "zephyr,flash-disk" compat disk in my device tree, like this:

	chosen {
        nordic,pm-ext-flash = &mx25r64;
    };

	msc_disk0 {
		compatible = "zephyr,flash-disk";
		partition = <&external_flash>;
		disk-name = "NAND";
		cache-size = <4096>;
	};

Unfortunately, this doesn't work as my mutli-image build partitioning is owned by the PM.  So despite the fact that this partition exists in the final build, it can't be referenced here.  Is there a workaround for this or better approach?

EDIT: To be clear, I do not want to delete the partition node (which is what every single example does), I want to reference the PM-generated partition.

I don’t want to use a SD card. Are you saying there is no way to reference PM generated partitions from the device tree?  If you don’t know the answer, please consider reassigning this to someone who may be able to help.

Hi,

Could you provide your devicetree, prj.conf and overlay files?

Hi, we are keen on getting an answer to the same question.

Did you find a solution?

I don’t think so but I’ll go back and look when I get a second. I ended up abandoning that feature for now.

Hi,

For reference, please have a look at partition manager documentation. Partition manager supports partitions in external flash memory using regions. For more information about partitions in external flash, please refer to external flash memory partitions.
