I am seeing the following error in my logs after attempting to update my device via DFU using the nRF Connect iOS app:
I: Starting bootloader
I: Primary image: magic=unset, swap_type=0x1, copy_done=0x3, image_ok=0x3
I: Secondary image: magic=good, swap_type=0x3, copy_done=0x3, image_ok=0x1
I: Boot source: none
I: Swap type: perm
I: Starting swap using move algorithm.
W: Not enough free space to run swap upgrade
W: required 225280 bytes but only 221184 are available
I: Bootloader chainload address offset: 0xc000
When I compile my app it looks like it's only taking ~68% of flash, and the message is saying I only need 4096 bytes more for it to work. But, I'm not sure how to change the partitions for this to work.
Memory region Used Size Region Size %age Used
FLASH: 33384 B 48 KB 67.92%
SRAM: 23744 B 64 KB 36.23%
IDT_LIST: 0 GB 2 KB 0.00%
How would I go about fixing this so I can update via DFU?
Below is the .dts partition section for my custom board's .dts file:
&flash0 {
partitions {
compatible = "fixed-partitions";
#address-cells = <1>;
#size-cells = <1>;
boot_partition: partition@0 {
label = "mcuboot";
reg = <0x00000000 0xc000>;
};
slot0_partition: partition@c000 {
label = "image-0";
reg = <0x0000C000 0x32000>;
};
slot1_partition: partition@3e000 {
label = "image-1";
reg = <0x0003E000 0x32000>;
};
scratch_partition: partition@70000 {
label = "image-scratch";
reg = <0x00070000 0xa000>;
};
storage_partition: partition@7a000 {
label = "storage";
reg = <0x0007a000 0x00006000>;
};
};
};
If it's helpful, here is the output from "west build -t partition_manager_report":
flash_primary (0x80000 - 512kB):

Thank you for any help you can give.
