Including a bootloader with an application

[Jerry Easley]

I want to include a dfu bootloader with an application.  I read here: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/app_dev/bootloaders_and_dfu/bootloader_adding.htmlthat I should include "CONFIG_SECURE_BOOT=y" in the prj.conf file. However when I do I get this most enigmatic error message: "FATAL ERROR: command exited with status 1: 'c:\ncs\toolchains\v2.3.0\opt\bin\cmake.EXE' --build 'c:\Nordic\MyApps\blinky\build'" at build time.

If I remove the "CONFIG_SECURE_BOOT=y" from the prj.conf file, the application builds normally,

Regards,

Jerry

Hi,

I have tested myself when nRF Secure Immutable Bootloader (NSIB) as immutable bootloader is set to be used, with following configuration option

CONFIG_SECURE_BOOT=y

and when adding mcuboot as upgradable bootloader is chosen with configuration options given below.

CONFIG_SECURE_BOOT=y
CONFIG_BOOTLOADER_MCUBOOT=y

I could not reproduce your issue and did not see build error.

You could try building your application from both VS Code and command line using "west build". In addition, you could try using NCS v2.4.0 instead of v2.3.0. Lastly, check if your build environment is working correctly.

Best regards,
Dejan

Hi Dejan,

I am using sdk version

Below is a screen snippet which shows an error:

This is supposed to be fixed by a pristine build; it isn't.

I have pasted in several of my project files; I apologize, but I can't figure out hoe to attach files to this interface.

Here is my prj.conf file:

CONFIG_USB_DEVICE_STACK=y
CONFIG_USB_DEVICE_PRODUCT="Zephyr USB console sample"
CONFIG_USB_DEVICE_PID=0x0004
#CONFIG_USB_DEVICE_INITIALIZE_AT_BOOT=n

#CONFIG_SERIAL=y
CONFIG_CONSOLE=y
CONFIG_UART_CONSOLE=y
CONFIG_UART_LINE_CTRL=y
CONFIG_SECURE_BOOT=y
CONFIG_BOOTLOADER_MCUBOOT=y

Here is my terminal log for a pristine build:

I thought I might be getting this error because my SDK was damaged somehow so, using the toolchain manager, removed both V2.3.0 and V2.4.0 and then reinstalled V2.4.0.  The problem persisted.

Regards,

Jerry

[Jerry Easley]

In order to isolate this problem I created a new project with the same main.c file as was above and with a prj.conf file san the two boot loader statements:

CONFIG_SECURE_BOOT=y
CONFIG_BOOTLOADER_MCUBOOT=y

I could build for both the nRF52480-dk and the nRF52480-dongle without issue.

When I add these two statements to the prj.conf fie

CONFIG_SECURE_BOOT=y
CONFIG_BOOTLOADER_MCUBOOT=y

Builds for both boards fail, Further, if I then remove the two bootloader statements, both boards STILL fail on build.  The addition of these two statements somehow irreversibly damages the build system files.

Jerry
