Using the Zephyr SDK on a clean install

DuckPaddle

I am using Circuit Dojo Zephyr SDK on a clean install of VS Code on a clean install of Pop_OS. I tried Build from the SDK on a virgin “app”. I get the response from west that “build” is an unknown command. Can you give me some direction?

Thanks,
George

Executing task: west build -b stm32h747i_disco_m4 -p -d build/stm32h747i_disco_m4 –sysbuild

usage: west [-h] [-z ZEPHYR_BASE] [-v] [-q] [-V] <command> …
west: unknown command “build”; workspace /home/duckpaddle/zephyrproject does not define this extension command – try “west help” and “west -vv status”

The terminal process “/bin/zsh ‘-c’, ‘west build -b stm32h747i_disco_m4 -p -d build/stm32h747i_disco_m4 –sysbuild’” terminated with exit code: 1.
Terminal will be reused by tasks, press any key to close it.

A few guesses here:

You are using a copy of Zephyr that was already downloaded/cloned. There’s typically a cmake cache that points to the previous setup you were using. In the ~/.cmake/ directory or ~/.config/cmake/ You can back it up and see if that makes a difference. I did that once with a repo I was using nRF Connect for VSCode and was able to swap over without destroying everything.
You already have west installed somewhere on your machine which is conflicting over the one that the extension installed

Thanks, I used the Zephyr SDK to download and install on a clean platform. Let me test your suggestions.
Thanks again.

Ok, this issue seems to be related to starting with “Create Project” as opposed to starting with “Init Repo”.
These options are offered on the initial run of the dojo zephyr tools.

West does not know “build” because “west init” has not been run.

Just to be clear, I have a “clean” system. This means that nothing has been run, only the VS Code, Python 3, GIT, and Circuit Dojo Zephyr SDK installed.

I tried the “Init Repo” option and entered “https://github.com/circuitdojo/nrf9160-feather-examples-and-drivers” for the repository address. It didn’t work and the Zephyr Tools is stuck on the “Initializing Project” panel.

Now my questions, I understand you are busy but any help would be appreciated.

1) If I start with “Create Project”, can I return to the “Init Repo” to run it?
2) Is it possible to open the terminal within VS Code and hop into the Python Virtual environment?
3) Do you have a good git URL that I can use to get started with the “Init Repo?”

If you need a noob to test your Zephyr SDK, I’m your guy (at least until I get better with this). I will make mistakes that an experienced Zephyr developer would not make.

Found a good url: https://github.com/zephyrproject-rtos/example-application for the “Init Repo.”

But it ends with:
I assume error code 2 is a bad thing….

1) If I start with “Create Project”, can I return to the “Init Repo” to run it?

That’s what the current Create Project does. If you interrupt that task you’ll have a partially completed download

2) Is it possible to open the terminal within VS Code and hop into the Python Virtual environment?

Of course, you’ll have to do it manually for now:

source .zephyrtools/env/bin/activate

3) Do you have a good git URL that I can use to get started with the “Init Repo?”

It should work with any Zephyr repo.

https://github.com/zephyrproject-rtos/zephyr.git

Is always a good one if you’re using vanilla Zephyr.

jaredwolff

If you create a vanilla zephyr project it should do all the work for you. Running init should be for projects that already exist that have a west.yml manifest.

Here’s the output when creating a new project

My guess is you’re trying to clone a repo into a folder that already has a Zephyr project. Let me know if that’s not the case. I just pushed an update to the extension to avoid these incompatible situations.

@DuckPaddle I just pushed another update to add opening of Zephyr shell:

jaredwolff THANK YOU!!!!

I discovered the issue was my issue. When executing the “Init Repo” action, I entered the https://github.com/zephyrproject-rtos/zephyr.git as you suggested into the text box and pressed Enter. The system responded with clearing the text I had entered and requesting a Enter or ESC key. I assumed this meant the system didn’t like my entry and re-entered the same text and pressed enter again. I assume this concatenated the two entries which didn’t end well for my system.

I have also encountered a more serious issue. I am using and stm32h747i_disco board that has an M4 and M7 core. Because the dropdown list doesn’t recognize the cores as individual entries I am unable to build the project. The acceptable name is stm32h747i_disco/stm32h747xx/m4.

Two solutions: 1) add another entry to the Project Settings Tile to allow the specification of the core variant or 2) allow the user to override the dropdown and enter his own thing.

Thanks again for your great project and your help!

@DuckPaddle just added 0.4.10 which should allow you to create a custom board

DuckPaddle

THANK YOU, I have now successfully built and loaded BLINKY!!!
Yea!

jaredwolff

Woo!
