Hello,
I'm getting the following error when attempting to perform a DFU. I'm using the Android nRF Connect app.

00> I: Image index: 0, Swap type: test
00> I: Image index: 1, Swap type: none
00> E: Failed to open flash area ID 1: -2
Flash Area ID of 1 indicates it's external flash. Error -2 is ENOENT. So it's saying that no such flash area exists? I suspect something is not configured correctly.
Here is my external flash devicetree snippet:

The project is based on the smart lock sample code. I had to increase the size of the bootloader region to get it to fit. Here is the pm_static_dfu.yml file:

I'm don't know how or if this yaml file relates to the partitions defined in the devicetree, but here are the devicetree partitions:
