No app_signed.hex in build folder

[linh]

Hi,

I try to build and programm Thing:91 with segger embedded Studio and need the file app_signed.hex to Flash the Firmware in Thing:91 without a external debug probe. After click Build -> Build Solution, i expected the file app_signed.hex in build Folder.

When i build the application asset_tracker, there are file app_signed.hex in the build folder. But when I build the sample mqtt_simple there are no file app_signed.hex in the build Folder. 

Do you know what have to be changed in order to generate app_signed.hex in the build forder?

Try adding these changes to the prj.conf file, so that it generates the app image(app_signed.hex) for mcuboot:

# MCUBOOT
CONFIG_BOOTLOADER_MCUBOOT=y
CONFIG_IMG_MANAGER=y
CONFIG_MCUBOOT_IMG_MANAGER=y

# Flash
CONFIG_FLASH=y
CONFIG_IMG_ERASE_PROGRESSIVELY=y
