Installation on Ubuntu

The following chapter will guide you through the CHESTER SDK installation on Ubuntu. It has been tested on versions Ubuntu 20.04 LTS and Ubuntu 22.04 LTS.

caution

Before you begin, make sure you comply with the chapter Requirements.

Installation Steps​

The installation steps are split into multiple sections. At the end, you will be able to build the blinky sample from the CHESTER SDK.

Set Up Device Rules​

  1. Open the Terminal application.

  2. Get the package with the udev rules:

    wget https://github.com/NordicSemiconductor/nrf-udev/releases/download/v1.0.1/nrf-udev_1.0.1-all.deb

  3. Install the package with the udev rules:

    sudo dpkg -i nrf-udev_1.0.1-all.deb

Install Packages​

  1. Remove the package with the udev rules:

    rm nrf-udev_1.0.1-all.deb

  2. Install the following APT packages:

    sudo apt install --no-install-recommends git cmake ninja-build gperf ccache dfu-util device-tree-compiler wget python3-dev python3-pip python3-setuptools python3-tk python3-wheel xz-utils file make gcc gcc-multilib g++-multilib libsdl2-dev

Install Toolchain​

  1. Create a target directory for the toolchain:

    mkdir -p $HOME/.local/opt

  2. Download and unpack the toolchain:

    wget -c https://github.com/zephyrproject-rtos/sdk-ng/releases/download/v0.14.1/zephyr-sdk-0.14.1_linux-x86_64.tar.gz -O - | tar -xz --directory $HOME/.local/opt

  3. Run the Zephyr SDK bundle setup script:

    $HOME/.local/opt/zephyr-sdk-0.14.1/setup.sh

Create Application​

  1. Create the directory for your application and switch to it:

    mkdir chester-app && cd chester-app
    tip

    Change the parameter chester-app to any desired name for your project directory.

  2. Initialize the Python virtual environment:

    python3 -m venv venv

  3. Activate the Python virtual environment:

    source venv/bin/activate
    caution

    When you close the shell (or your text editor with the integrated terminal), you must reactivate the virtual Python environment. Call this command (used in the procedure above): source venv/bin/activate. In the future, you may have various West workspaces with different versions of the Python packages, and thanks to the virtual environment concept, these will not suffer from version conflicts.

  4. Upgrade the pip package:

    pip install --upgrade pip

  5. Install the West tool:

    pip install west

  6. Initialize the West workspace where you want to start your project:

    west init -m git@gitlab.hardwario.com:chester/skeleton.git --manifest-rev main

  7. Set the default board to CHESTER (nRF52840):

    west config build.board chester_nrf52840

  8. Synchronize the West workspace:

    west update

  9. Export Zephyr environment:

    west zephyr-export

  10. Install the Python dependencies:

    pip install -r zephyr/scripts/requirements.txt
    pip install -r nrf/scripts/requirements.txt
    pip install -r bootloader/mcuboot/scripts/requirements.txt
    pip install -r chester/scripts/requirements.txt

Test Build​

  1. Go to the blinky sample directory:

    cd chester/samples/blinky

  2. Check that you can build the sample:

    west build

    The final build result should look like this:

    Memory region         Used Size  Region Size  %age Used
            FLASH:      112320 B         1 MB     10.71%
             SRAM:       60576 B       256 KB     23.11%
         IDT_LIST:          0 GB         2 KB      0.00%
