How to set PlatformIO to use the latest branch of Zephyr

Development Platforms

#1

I am trying to use the latest Zephyr branch (v2.4.0) with my PlatormIO nordicnrf52 Zephyr project.

I have cloned https://github.com/zephyrproject-rtos/zephyr and I was wondering how I can set it to be used? I have tried, unsuccessfully to use information from https://community.platformio.org/t/set-package-repository-and-version-in-platformio-ini/14211/7.

On a related note when is Zephyr v2.4.0 going incorporated into PlatformIO?

Custom Zephyr Framework - Use West & PlatformIO

Further information is needed on what the exact error was if you want to go that path.

Only the devs can answer that one. I’ve seen that @valeros has done an Arduino-core update for the nordicnrf52 platform. Maybe Zephyr is next?

#3

I have cloned https://github.com/zephyrproject-rtos/zephyr to “/Users/mdcraver/opt/zephyr/”.

Using this I tried the following and gotten the following error.

framework = zephyr
platform_packages =
framework-zephyr @ file:///Users/mdcraver/opt/zephyr/.git

Tool Manager: Installing file:///Users/mdcraver/opt/zephyr/.git
Error: Could not find one of ‘package.json’ manifest files in the package
The terminal process “platformio ‘run’” terminated with exit code: 1.

You can create one based on the previous package.json (~/.platformio/packages/framework-zephyr/package.json). Example:

{
  "name": "framework-zephyr",
  "version": "2.20400.201023",
  "description": "Zephyr is a new generation, scalable, optimized, secure RTOS for multiple hardware architectures",
  "keywords": [
    "framework",
    "rtos",
    "hal"
  ],
  "homepage": "https://www.zephyrproject.org",
  "license": "Apache-2.0",
  "repository": {
    "type": "git",
    "url": "https://github.com/zephyrproject-rtos/zephyr"
  }
}

also don’t forget to copy over the ~/.platformio/packages/framework-zephyr/scripts/platformio folder again because that’s no in the main Zephyr repo.

Also note that Zephyr is actually multiple packages

framework-zephyr-canopennode

framework-zephyr-cmsis
framework-zephyr-fatfs
framework-zephyr-hal-nordic
framework-zephyr-hal-nxp
framework-zephyr-hal-st
framework-zephyr-hal-stm32
framework-zephyr-libmetal
framework-zephyr-littlefs
framework-zephyr-loramac-node
framework-zephyr-lvgl
framework-zephyr-mbedtls
..
framework-zephyr-mipi-sys-t
framework-zephyr-nffs
framework-zephyr-open-amp
..
framework-zephyr-segger
framework-zephyr-tinycbor
framework-zephyr-tinycrypt
framework-zephyr-trusted-firmware-m

so I think you also need to at least update framework-zephyr-hal-nordic to the 2.4.0, which is at https://github.com/zephyrproject-rtos/hal_nordic.

I did these things to use master branch of Zephyr:

  1. Make sure that Zephyr is already installed automatically via Platformio (path ~/.platformio/packages/framework-zephyr/ should exist)
  2. Clone Zephyr repo (f.e. to ~/Downloads/zephyr-repo/) and checkout to desired commit
  3. Add this line to platformio.ini:
    platform_packages = framework-zephyr @ file:///Users/myUser/Downloads/zephyr-repo/
  4. Copy package.json file and ./scripts/platformio folder from ~/.platformio/packages/framework-zephyr/ to your ~/Downloads/zephyr-repo/
  5. Remove ~/.platformio/packages/framework-zephyr/ folder
  6. Run clean and build, it should “install” your desired revision of Zephyr from ~/Downloads/zephyr-repo/ to ~/.platformio/packages/framework-zephyr/

Hi jarynznosa,
thank you for your clear explanation. I installed another version of zephyr as you described here. In building however I got an error saying:
.pio/build/nrf52833dk_nrf52833/zephyr/dev_handles.c’ not found, needed by target `.pio/build/nrf52833dk_nrf52833/zephyr_final/zephyr/dev_handles.c.o’.
Do you know what would cause this issue?
