Thanks for your reply! I have enabled CONFIG_BOOTLOADER_MCUBOOT in prj.conf file. But I still can't find zephyr.signed.bin file. But I can use mcuboot-img-parser with app_update.bin file.

./mcuboot-img-parser app_update.bin

Hi,

Not sure what the zephyr.signed.bin includes and how it's generated.

Please check out the MCUboot output build files if you enable CONFIG_BOOTLOADER_MCUBOOT with the project.
