Setup a example zephyr project with west
West is the “swiss army knife” of the Zephyr project and helps to configure, build, flash and debug your Zephyr application. Here are some steps which show how to overcome the hurdles.
First install west as user with the python installer and add the execution path to your PATH environment variable of your shell config file:
guest:~$ pip3 install --user west guest:~$ echo 'PATH=$PATH:~/.local/bin' >> ~/.bashrc
guest:~$ west --version West bootstrapper version: v0.4.0 (/home/guest/.local/lib/python3.7/site-packages/west/_bootstrap)
Get Zephyr OS and friends
Now clone and update west and zephyr repositories into the directory
zephyrproject by the use of west:
guest:~$ west init zephyrproject guest:~$ cd zephyrproject guest:~/zephyrproject$ west update
Install Python packages required by Zephyr:
guest:~/zephyrproject$ pip3 install --user -r zephyr/scripts/requirements.txt
Next step is to install the GNU ARM Embedded Toolchain supported by Eclipse described here.
guest:~$ echo 'ZEPHYR_TOOLCHAIN_VARIANT=gnuarmemb' >> ~/.bashrc guest:~$ echo 'GNUARMEMB_TOOLCHAIN_PATH=~/opt/xPacks/@gnu-mcu-eclipse/arm-none-eabi-gcc/8.2.1-1.7.1/.content/bin' >> ~/.bashrc
Please note that different version of the toolchain (here 8.2.1-1.7.1) could be installed, so adjust the path for
After reopening the shell all the variables should be set. A few prefered settings of west like a pristine build directory before building could be applied by:
guest:~ cd ~/zephyrproject/zephyr guest:~/zephyrproject/zephyr$ west config build.pristine auto
Now it's time to build a sample application for the Olimexino board. The build directory to be used is
guest:~/zephyrproject/zephyr$ source zephyr-env.sh guest:~/zephyrproject/zephyr$ west build -p -b olimexino_stm32 samples/hello_world -G'Eclipse CDT4 - Ninja'
Before flashing or debugging anything, the Segger Jlink Debugger should be installed as described here. After connecting the debugger properly to the Olimexino and the PC, it is time to flash the generated binary to the board by west:
guest:~/zephyrproject/zephyr$ west flash --runner jlink
To start a simple gdb console session:
guest:~/zephyrproject/zephyr$ west debug --runner jlink
Please create another page for creating build and debug project in eclipse west build -p -b olimexino_stm32 samples/hello_world -G'Eclipse CDT4 - Ninja' In Eclipse import project “Existing Projects into Workspace”.
