Thanks, this sample app worked! The application can now be up to 975 kB, says the partition report:

Did you remember to change something in the application before testing the DFU?

I have struggled some to update the sample to v2.3.0 myself.

But I got something working now.
The sample likely have too many configurations enabled, but it works for me.
I suggest that you test with this sample, and then go from there:

devzone.nordicsemi.com/.../mcuboot_5F00_smp_5F00_ble_5F00_simultaneous_5F00_2_5F00_3_5F00_0.zip

Thanks, I tested it with v2.3.0, and it compiles, but when I try the update with the zip file from nRF Connect (latest version 4.26.1) from an Android phone, it spins for a few seconds, and then closes the update dialog, no images are transferred.

Hi,

Have a look at my unofficial Bootloader samples, and maybe specifically the nRF5340 bootloader samples.

Is this what you need?

PS: These was previously tested for v2.2.0, and there have been some changes to paths for mcumgr in v2.3.0, so you might have to fix some build errors.
The project configuration for multi image should still be the same I think.
Let me know if you need help with these
