Building RISC-V Blinky for RPI Pico 2 Needs More Installs to run INSIDE the container (like GitLab CI does)

[DarwinJS]

GitLab CI runs inside the container - so I’m not sure if lacking some of these runtimes assumes using the tools via docker as a sidecar on a laptop?

sudo docker run -it ghcr.io/embeddedcontainers/zephyr:arm-0.17.4SDK bash 

#fix python tools (otherwise `west boards` does not work without jsonschema and `west build` for risc-v does not work without pyelftools)
pip install jsonschema pyelftools

#setup riscv build
apt-get update && apt-get install -y xz-utils wget #required for setup.sh
pushd /opt/toolchains/zephyr-sdk-0.17.4
./setup.sh -t riscv64-zephyr-elf
popd

#get source
cd $HOME
mkdir -p zephyrproject
cd zephyrproject
git clone https://github.com/zephyrproject-rtos/zephyr 

west init -l zephyr
west update

#fix source

cat > /root/zephyrproject/zephyr/samples/basic/blinky/boards/rpi_pico2_rp2350a_hazard3.overlay << 'EOF'
/ {
    aliases {
        led0 = &led;
    };

    leds {
        compatible = "gpio-leds";
        led: led_0 {
            gpios = <&gpio0 25 GPIO_ACTIVE_HIGH>;
            label = "LED";
        };
    };
};
EOF

west boards #should work
pushd zephyr
west build -b rpi_pico2/rp2350a/hazard3 samples/basic/blinky

output:

Thanks for checking out this project! I don't have a lot of experience working with GitLab but it would be great to make these containers useable there.

For starters, have you seen https://github.com/embeddedcontainers/examples-zephyr-helloworld? One challenge to making reusable build containers is that the Zephyr dependencies is unique to every project, including the python dependencies. So it would be essentially impossible to pre-install them here. You can see how I install the requirements.txt as the last step before launching Codespaces. I assume you can do something similar in Gitlab.

One other thing - you're using zephyr:arm-0.17.4SDK but you probably want ghcr.io/embeddedcontainers/zephyr:riscv64-0.17.4SDK.

HTH!
