Hi Marco,
I appreciate that you have made a seperate ticket for your issue since it's unrelated to the original post.
I will follow up the other case!

Best Regards,

Martin L.

Yes, it does happen for every sample and the build folder is clean.

Here is my input (here I was building the coap_client)

and I get the same result

With this CMakeError file written in the build folder

devzone.nordicsemi.com/.../CMakeError.log

Can you confirm the build folder is clean?

Hi, thanks again for the help.

I tried reinstalling the SDK and checked out if all the repositories were up to date, then I used west to build both the secure_boot sample and the at_client but I got the same result. This is what I get with the secure_boot (same error as when using cmake and ninja).

Could it be a problem with my computer and not with the build files?

Hi Marco,

Does this happen for every sample?

If not, then there may be an issue with the build files.

Please clean the folder:

rm *-r

and try to build again.

Another suggestion is to update the master branch in the nrf repo.

git pull

And the rest of the repoes (easiest if you have west).

west update

Extra tip:

Optional, you can use the West tool to build/flash applications as well.

#using west to build
west build -b nrf9160_pca10090ns -d build

#using west to flash
west flash -d build

(b = board; d = directory)

(another neat thing when using west is that you do not need to set up the build environment before you build the application)

Hi, after switching to the version “7-2018-q2-update” of the toolchain I was able to go past that issue but I still cannot compile my project. I tried both using cmake+ninja and west but it reports the same problem.
This is the output after using cmake (the same issue applies when I try to use the secure_boot application before using coap_client).

It seems that I cannot compile my project since there is no .hex file in the zephyr folder, even though it writes some build files to the build folder.

Do you have any ideas on how to solve this problem?

Thank you for the information, I will try reinstalling the toolchain.
It would be great if you could update me on the Segger release. Do you know if it's a matter of weeks or months for its release?

Hello Marco,

I would recommend you to switch to the version 7-2018-q2-update, since the newest version (8-2018-q4-major) has a critical bug and should not be used.
I think the issue can be the same as Hellesvik is experiencing in this thread.

(There may also be an issue with spaces in the paths)

Here is my path to the ARM Toolchain:

I set:

export GNUARMEMB_TOOLCHAIN_PATH=/c/gnuarmemb

and here is what's in this path: C:\gnuarmemb\arm-none-eabi\

There is a Segger release that is coming very soon, I can update you when it's ready.

Best Regards,

Martin L.

Hi, I'm trying to build the coap_client application using the command line on Windows since I'm having problems using Segger.
I already flashed the Secure Boot, now I'm trying using this commands

cd C:\Nordic_SDK\ncs\zephyr

zephyr-env.cmd

set ZEPHYR_TOOLCHAIN_VARIANT=gnuarmemb

set GNUARMEMB_TOOLCHAIN_PATH = “C:\Program Files (x86)\GNU Tools ARM Embedded\8 2018-q4-major”

cd C:\Nordic_SDK\ncs\nrf\samples\nrf9160\coap_client

mkdir build && cd build

cmake .. -DBOARD=nrf9160_pca10090ns -GNinja

ninja flash

But then it reports the following message

C:\Nordic_SDK\ncs\nrf\samples\nrf9160\coap_client\build>cmake .. -DBOARD=nrf9160_pca10090ns -GNinja
Zephyr version: 1.14.0
-- Found PythonInterp: C:/Python37/python.exe (found suitable version "3.7.2", minimum required is "3.4")
-- Selected BOARD nrf9160_pca10090ns
CMake Error at C:/Nordic_SDK/ncs/zephyr/cmake/extensions.cmake:1104 (message):
Assertion failed: GNUARMEMB_TOOLCHAIN_PATH is not set
Call Stack (most recent call first):
C:/Nordic_SDK/ncs/zephyr/cmake/toolchain/gnuarmemb/generic.cmake:11 (assert)
C:/Nordic_SDK/ncs/zephyr/cmake/generic_toolchain.cmake:55 (include)
C:/Nordic_SDK/ncs/zephyr/cmake/app/boilerplate.cmake:395 (include)
CMakeLists.txt:9 (include)

It says that the Toolchain Path is not set but I set it with the Gnuarmemb Path I set in the Getting Started Assistant to verify if the Toolchain was correctly installed. Do I have to set a different path?

Thanks in advance for any clarification you can give me.

On a side note, will it be possible to build projects using Segger soon? Everytime I try to build a project it gives me an error unless I switch to the v3.0.0 release and then it works.

Hi Jack,

Just adding to what jbrzozoski is referring to:

When using the command line you need to define the environment variables for the GNU Arm Embedded toolchain:

export ZEPHYR_TOOLCHAIN_VARIANT=gnuarmemb
export GNUARMEMB_TOOLCHAIN_PATH=/c/gnuarmemb

Set up build environment

cd $NCS_BASE/zephyr
source zephyr-env.sh

To build and flash the application using ninja (you can also use cmake to build with make instead of ninja)

cd $NCS_BASE/nrf/samples/nrf9160/mqtt_simple/
mkdir build && cd build

# Use cmake to configure a Ninja-based build system:
cmake -GNinja -DBOARD=nrf9160_pca10090ns ..

# Now run ninja on the generated build system:
ninja
ninja flash

Also worth noticing that there is a difference when building Secure/Non-Secure Zephyr applications.

Extra tip:

To flash precompiled .hex files you can either use the nRF Connect Programmer application or do it via command line nrfjprog:

nrfjprog --program <application>.hex -f nrf91 --sectorerase -r --verify

Best Regards,
Martin L.

Yes. Most of what is happening "behind the scenes" is creating an output directory, running cmake, and possibly adjusting configuration. All of this is based on normal Zephyr build flow, which was developed on command line primarily.

You can find more detailed instructions here:

Jack,

I have not begun to develop the nRF9160 to date, but my nRF52 series development utilizes the armgccs folder of the SDK. This only requires a text editor and a command line interface with the complete toolchain in place. I do think it is very effective, but there is a slight learning curve from compiling to programming the chips. I will attach a recipe for the toolchain on to a windows 10 machine. The recipe places the toolchain on to a work environment but I am not sure you should have any problem putting this on to a server. Good luck!
