bsp-registry-tools 0.0.1.3

Advantech Board Support Package (BSP) Registry Manager

bsp-registry-tools

Python tools to build, fetch, and work with Yocto-based BSPs using the KAS build system.

Overview

bsp-registry-tools provides a command-line interface and Python API for managing Advantech Board Support Packages (BSPs). It uses YAML-based registry files to define BSP configurations, build environments, and Docker containers, making reproducible Yocto builds straightforward.

Key Features

• 📋 BSP registry management via YAML configuration files
• 🐳 Docker container support for reproducible build environments
• 🔧 KAS integration for Yocto-based builds (kas, kas-container)
• 🖥️ Interactive shell access to build environments
• 🔄 Environment variable expansion ($ENV{VAR} syntax)
• 📤 Configuration export for sharing and archiving build configs
• ✅ Comprehensive validation of configurations before building

Quick Start

1. Create a BSP Registry File

Create a bsp-registry.yml file (see examples/bsp-registry.yml):

specification:
  version: "1.0"

environment:
  - name: "DL_DIR"
    value: "$ENV{HOME}/yocto-cache/downloads"
  - name: "SSTATE_DIR"
    value: "$ENV{HOME}/yocto-cache/sstate"

containers:
  - debian-bookworm:
      image: "bsp/registry/debian/kas:5.1"
      file: Dockerfile
      args:
        - name: "DISTRO"
          value: "debian-bookworm"
        - name: "KAS_VERSION"
          value: "5.1"

registry:
  bsp:
    - name: poky-qemuarm64-scarthgap
      description: "Poky QEMU ARM64 Scarthgap (Yocto 5.0 LTS)"
      build:
        path: build/qemu-arm64-scarthgap
        environment:
          container: "debian-bookworm"
        configuration:
          - kas/scarthgap.yml
          - kas/qemu/qemuarm64.yml

2. List Available BSPs

bsp list

- poky-qemuarm64-scarthgap: Poky QEMU ARM64 Scarthgap (Yocto 5.0 LTS)

3. Build a BSP

bsp build poky-qemuarm64-scarthgap

4. Enter Interactive Shell

bsp shell poky-qemuarm64-scarthgap

Python API

You can also use bsp-registry-tools as a Python library:

from bsp import BspManager, EnvironmentManager, KasManager

# Load and manage BSP registry
manager = BspManager("bsp-registry.yml")
manager.initialize()

# List BSPs programmatically
for bsp in manager.model.registry.bsp:
    print(f"{bsp.name}: {bsp.description}")

# Get a specific BSP
bsp = manager.get_bsp_by_name("poky-qemuarm64-scarthgap")

# Environment variable management with $ENV{} expansion
from bsp import EnvironmentVariable
env_vars = [
    EnvironmentVariable(name="DL_DIR", value="$ENV{HOME}/downloads"),
]
env_manager = EnvironmentManager(env_vars)
print(env_manager.get_value("DL_DIR"))  # Expanded path

# Use KasManager directly
kas = KasManager(
    kas_files=["kas/scarthgap.yml", "kas/qemu/qemuarm64.yml"],
    build_dir="build/my-bsp",
    use_container=False,
)
kas.validate_kas_files()

Publishing to PyPI

This repository uses GitHub Actions for automated publishing.

Setup

1. Create PyPI and TestPyPI accounts and configure Trusted Publishers:

   • PyPI: Add GitHub Actions publisher for Advantech-EECC/bsp-registry-tools
   • TestPyPI: Same configuration on test.pypi.org

2. Create GitHub Environments named pypi and testpypi in your repository settings.

Publish Workflow

Automatic (on GitHub Release):

• Creating a non-prerelease GitHub Release automatically publishes to both TestPyPI and PyPI.
• Creating a prerelease publishes to TestPyPI only.

Manual:

GitHub → Actions → "Publish to PyPI" → Run workflow → Select environment
