Hi,
When running the python script in attachments
import argparse
import os
import subprocess
import sys
def install_toolchain_and_sdk(version, install_dir):
print(f"Installing SDK version {version} using sdk-manager...")
result = subprocess.run([
"nrfutil", "sdk-manager", "install", version, "--install-dir", install_dir
], capture_output=True, text=True)
if result.returncode != 0:
print("Error installing SDK:", result.stderr)
sys.exit(1)
print("SDK installed successfully.")
def launch_build(sdk_version, project_path, build_dir, board, config, install_dir, custom_board_dir):
print(f"Setting up environment for SDK version {sdk_version}...")
nrf_command = [
"nrfutil", "sdk-manager", "toolchain", "launch",
"--ncs-version", sdk_version,
"--chdir", project_path,
"--install-dir", install_dir,
"--"
]
west_command = [
"west", "build",
"--sysbuild",
"--pristine",
"-b", board,
"-d", build_dir,
project_path,
]
cmake_args = []
if config:
cmake_args.append(f"-DCONF_FILE={config}")
if custom_board_dir:
cmake_args.append(f"-DBOARD_ROOT={custom_board_dir}")
if cmake_args:
west_command += ["--"] + cmake_args
env = os.environ.copy()
env["ZEPHYR_BASE"] = install_dir + '\\' + sdk_version + '\\' + "zephyr"
print(env["ZEPHYR_BASE"])
result = subprocess.run(nrf_command + west_command, text=True, env=env)
print(result.stdout)
if result.returncode != 0:
print("Build failed:", result.stderr)
sys.exit(1)
print("Build completed successfully.")
def main():
parser = argparse.ArgumentParser(description="Build a Nordic NRF Connect application with sysbuild.")
parser.add_argument("--sdk-version", required=True, help="The version of the SDK/toolchain to install.")
parser.add_argument("--project-path", required=True, help="Path to the NRF Connect project.")
parser.add_argument("--build-dir", required=True, help="Destination directory for the build output.")
parser.add_argument("--board", default="nrf5340dk_nrf5340_cpuapp", help="Target board for the build (default: nrf5340dk_nrf5340_cpuapp).")
parser.add_argument("--config", help="Optional configuration file for the build.")
parser.add_argument("--install-dir", required=True, help="Directory to install the SDK and toolchain.")

args = parser.parse_args()
install_toolchain_and_sdk(args.sdk_version, args.install_dir)
launch_build(args.sdk_version, args.project_path, args.build_dir, args.board, args.config, args.install_dir, args.custom_board_dir)
if __name__ == "__main__":
main()
By invoking it like this :
python.exe ./nrf_build.py --sdk-version v3.0.2 --project-path <path_of_the_project> --build-dir <build_dest> --install-dir D:\ncs --custom-board-dir <path_of_the_project> --board rf2g4/nrf52833
I get the error:
... -- Configuring done -- Generating done CMake Error: Running 'D:/ncs/toolchains/0b393f9e1b/opt/bin/ninja.exe' '-C' 'D:/builds/opt.rf.2g4/build/opt.rf.2g4' '-t' 'recompact' failed with: ninja: error: build.ninja:9629: lexing error CMake Generate step failed. Build files cannot be regenerated correctly. CMake Error at cmake/modules/sysbuild_extensions.cmake:514 (message): CMake configure failed for Zephyr project: opt.rf.2g4 Location: <project_path> Call Stack (most recent call first): cmake/modules/sysbuild_images.cmake:43 (ExternalZephyrProject_Cmake) cmake/modules/sysbuild_default.cmake:21 (include) D:/ncs/v3.0.2/zephyr/share/zephyr-package/cmake/ZephyrConfig.cmake:75 (include) D:/ncs/v3.0.2/zephyr/share/zephyr-package/cmake/ZephyrConfig.cmake:92 (include_boilerplate) D:/ncs/v3.0.2/zephyr/share/sysbuild-package/cmake/SysbuildConfig.cmake:8 (include) template/CMakeLists.txt:10 (find_package) -- Configuring incomplete, errors occurred!
In fact, the generated build.ninja file contains some strange char (seems to be the \x1B escape char) at the start of indicated line, in # Custom command for zephyr\cmake\reports\CMakeFiles\ram_report and # Custom command for zephyr\cmake\reports\CMakeFiles\rom_report
When I do it from cmd line:
1. cd D:\ncs\v3.0.2\zephyr then run zephyr-env.cmd to set the ZEPHYR_BASE env var
2. nrfutil sdk-manager toolchain launch --ncs-version v3.0.2 --chdir <project-path> --install-dir D:\ncs -- west build --sysbuild --pristine -b rf2g4/nrf52833 -d <build_dest> <project-path> -- -DBOARD_ROOT=<path_of_the_project>
It works completely. Anyone having trouble to launch the build from a python script ? (tested with python 3.11, 3.12, 3.13 with same failure, also trying with older SDK gives the same results : v2.9.1)
We need to launch the build from our internal build tool written in python, I don't figure out why I get different results from calling the exact same cmd from the CLI vs in python
Thanks
