Issue with command line compilation of NRF9160 samples

[Ryan Farrelly]

Hello,

I have configured the toolchain and SDK by following the NRF Connect getting started guide and followed the below steps to compile the mqtt_simple application (on master branch and using a MAC):

export ZEPHYR_TOOLCHAIN_VARIANT=gnuarmemb

export GNUARMEMB_TOOLCHAIN_PATH="/path/to/gcc-arm-none-eabi-Qx-2018/"

source /path/to/ncs/zephyr/zephyr-env.sh

cd /path/to/ncs/nrf/samples/nrf9160/mqtt_simple/

mkdir build && cd build

cmake .. -DBOARD=nrf9160_pca10090ns -GNinja

After executing cmake this is the output:

Zephyr version: 1.14.0

-- Selected BOARD nrf9160_pca10090ns

-- Found west: /usr/local/bin/west (found suitable version "0.5.5", minimum required is "0.5.4")

Any help would be appreciated.

Ok, managed to get this to work i.e, build, compile and flash.

Before anything, follow the steps in the NRF Connect making sure all dependancies are installed but stay on Master branch.

Set up your .bash_profile like this:

export ZEPHYR_BASE=/path/to/ncs/zephyr
export ZEPHYR_TOOLCHAIN_VARIANT=gnuarmemb
export GNUARMEMB_TOOLCHAIN_PATH=/path/to/gcc-arm-none-eabi-7-2018-q2-update
source /path/to/ncs/zephyr/zephyr-env.sh

From the ncs root directory:
west init -l nrf
west update

Go to mqtt_simple/build ( clean the build folder if already exists )
cmake -DBOARD=nrf9160_pca10090ns -GNinja ..

NOTE: You may get an error about ‘pykwalify’ not being installed:
pip uninstall pykwalify
pip install pykwalify

Run cmake:
cmake -DBOARD=nrf9160_pca10090ns -GNinja ..
ninja
ninja flash

NOTE: Make sure you have the latest nrfjprog otherwise the ninja flash command won’t work and will complain about memory access alignment. And of course, the secure boot should be flashed prior to the main application.

I have the same problem.

The issue is that with Segger Embedded Studio 4.14 (Nordic Version) it is NOT possible to build code after 0.3.X.
It works on the command line with generating ninja files with cmake and then building with ninja.

If I copy the command line that is displayed in the SES output it works also!!!
Therefore the environment variables that I set in the .bashrc are obviously set in the terminal but do not get defined when starting SES from the desktop, make the difference.
If I start SES directly from the terminal it works also.

What also works is starting the project with SES then coping the command line to the terminal and let the project generate. Then I can open the project normally with SES.

So Nordic / Segger  please have a look at this issue ....

Best regards

Martin Thanks for letting us know! We are aware of this issue & are busy looking for a fix.

Ryan Farrelly Thanks for the tips!

In addition to using cmake & ninja, it is also possible to use the Zephyr west tool to build & program the board. These two links helped me figure this out: link 1, link 2.

Inside ncs/zephyr/zephyr-env.cmd:

@echo off
set ZEPHYR_BASE=%~dp0

if exist "%userprofile%\zephyrrc.cmd" (
	call "%userprofile%\zephyrrc.cmd"
)

If you define zephyrrc.cmd inside your user profile (i.e. C:/Users/<username>/), you can write:

@echo off
echo zephyrrc_running

set ZEPHYR_TOOLCHAIN_VARIANT=gnuarmemb
set GNUARMEMB_TOOLCHAIN_PATH=C:\gnuarmemb

That way, when you call zephyr-env.cmd from a command prompt window, you set the Zephyr base, zephyr toolchain variant & gnuarmemb toolchain path without needing to write the three commands each time. This may not work with a bash window (e.g. git bash) because the username may be different.

You can then follow this link to download NCS using west. To build the at_client example for example, change directory to ncs/samples/nrf9160/at_client & then run the following commands:

west build -b nrf9160_pca10090ns -d build
west flash -d build

You can then flash using:

west flash -d build
