Hi, I am having problem making DFU work on nrf52832 using nrf connect sdk 2.6.0. Below is my mcuboot.conf under child_image and prj.conf. Please guide me where I am wrong. Also when I set CONFIG_SINGLE_APPLICATION_SLOT, it builds fine but when I disables it, it doesn't build due to size issue.
&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 0x2C000>;
};
slot1_partition: partition@38000 {
label = "image-1";
reg = <0x00038000 0x2C000>;
};
storage_partition: partition@64000 {
label = "storage";
reg = <0x00064000 0x4000>;
};
};
};
