Cannot build new image for FOTA through MCUboot

Question

Hi.

I want to build firmware for FOTA into the slot1 partition.

I'm using NCS 2.5.0 in Visual Studio Code Envrionment.

I already build primary firmware(old firmware) with mcuboot and it works well.

but I want to build new image for update.

As I know, MCUBoot read slot1 that new firmware is located in.

So I want to build new firmware in slot 1, but It doesn't work.

I add CONFIG_BUILD_S1_VARIANT=y and CONFIG_SECURE_BOOT, but Compiler print out about error on Cmake.

Here is my error log

How can I build firmware for Slot 1?

Hi, 
 jswcomkr said: I modified prj.conf in ncs/v2.5.0/nrf/samples/bootloader, but I didn't set this path by myself. 
 I would not suggest you modify prj.conf of ncs/v2.5.0/nrf/samples/bootloader directly. You can add the NSIB as a child image to your application by enabling CONFIG_SECURE_BOOT=y. Here is an command exampl e. 
 jswcomkr said: 1. How can I modify s1 image configuration file path? 
 When adding the NSIB as a child image by enabling CONFIG_SECURE_BOOT=y, you can create child_image\create b0.conf under the application to overwrite the configuration. 
 
 jswcomkr said: 2. What is the B0, S0, S1 Image(Its meaning) 
 
 B0 is nRF Secure Immutable Bootloader (NSIB). S0 and S1 are updateable MCUboot. See https://developer.nordicsemi.com/nRF_Connect_SDK/doc/2.5.0/nrf/samples/bootloader/README.html#pre-signed-variants 
 jswcomkr said: 3. Which image can be used as upgrade image? I got lots of hex files.(Plz see below image) 
 We have https://developer.nordicsemi.com/nRF_Connect_SDK/doc/2.5.0/nrf/config_and_build/config_and_build_system.html#output-build-files which describes signed_by_mcuboot_and_b0_s0_image_update, which is the image you will want to use. Also, see t his post. 
 jswcomkr said: 4. Finally, How can I set the start / end address of each image? I want to use MCUboot-Primary Slot-Secondary Slot structrue. 
 It would be handled by partition manager which would be enabled automatically with muti-build. 
 jswcomkr said: 5. I want to design my MCU's partition as follow:(pm_static.yml in project folder) 
 Remove the pm_static.yml. Let the partition manager handle it for you. 
 
 jswcomkr said: My intend is that s0 is primary slot, s1 is secondary slot for new firmware, and mcuboot is for bootloader. 
 S0 and S1 are for updating the mcuboot instead of app. See https://developer.nordicsemi.com/nRF_Connect_SDK/doc/2.5.0/nrf/samples/bootloader/README.html#pre-signed-variants 
 
 jswcomkr said: As you know, nRF52832 has 512KB internal flashes, so I divided it in 3 pieces. but it is not work. 
 Do you want to update mcuboot or just the app? 
 If you just want to update the app image, you can just enable the DFU as my colleague suggested in this post . Then, the memory layout would look like this
