The official TQ CI repository includes all required layers as submodules:
```bash ```bash
cd $MIRROR_BASE/sources cd ${UT_BASE}
# Clone Poky (Yocto reference) - Scarthgap branch # Clone ci-meta-tq with all submodules (Scarthgap branch)
git clone -b scarthgap --depth 1 \ git clone --branch scarthgap.TQ.ARM.BSP.0006 \

cd poky-scarthgap cd ci-meta-tq
# Full clone for complete history (optional but recommended for approval)
git fetch --unshallow
cd $MIRROR_BASE/sources # Verify submodules are initialized
git submodule sync
git submodule update --init
# Verify structure
ls -la sources/
# Should show: meta-tq, poky, meta-openembedded, etc.
``` ```

git describe --tags # Should list tqma6ulx-mba6ulx and other machines
# Should show: yocto-5.0.x or similar
``` ```
--- ---
## Step 3: Clone OpenEmbedded Meta-Layer ## Step 3: Configure Build Environment for UT
### 3.1 Create Site Configuration
Create central configuration file `~/.yocto/site.conf`:
```bash ```bash
cd $MIRROR_BASE/sources mkdir -p ~/.yocto
# Clone meta-openembedded (contains essential recipes) cat > ~/.yocto/site.conf <<'EOF'
git clone -b scarthgap --depth 1 \ # UT Project Configuration
https://git.openembedded.org/meta-openembedded \ # Build: UT (Universität/Projekt)
meta-openembedded # Target: TQMa6UL on MBa6x
# Date: 2026-03-01
cd meta-openembedded # Mirror directories (outside home for space)
git fetch --unshallow DL_DIR ?= "/srv/yocto/downloads"
SSTATE_DIR ?= "/srv/yocto/sstate-cache"
cd $MIRROR_BASE/sources # Create directories
EOF
# Create system directories
sudo mkdir -p /srv/yocto/downloads /srv/yocto/sstate-cache
sudo chown -R "$USER:$USER" /srv/yocto
``` ```
**Included sub-layers:** ### 3.2 Initialize Build Environment
- `meta-oe` - Base additional recipes
- `meta-python` - Python packages
- `meta-networking` - Network tools
- `meta-filesystems` - Filesystem tools
- `meta-perl` - Perl modules
---
## Step 4: Clone TQ BSP Layer
```bash ```bash
cd $MIRROR_BASE/sources cd ${UT_BASE}/ci-meta-tq
# Clone TQ BSP layer - specific version for TQMa6UL # Set machine for TQMa6UL
git clone -b scarthgap.TQ.ARM.BSP.0006 --depth 1 \ export MACHINE=tqma6ulx-mba6ulx
https://github.com/tq-systems/meta-tq.git \
meta-tq
cd meta-tq # Alternative if using multi-config:
git fetch --unshallow # export MACHINE=tqma6qdl-multi-mba6x
# Verify the branch # Initialize build environment (creates build_ut directory)
git branch -a | grep scarthgap . ./setup-environment build_ut imx
cd $MIRROR_BASE/sources # Verify configuration
``` bitbake -e | grep -E "^MACHINE=|^DL_DIR=|^SSTATE_DIR="
**Critical:** Ensure you use the exact tag `scarthgap.TQ.ARM.BSP.0006` for reproducibility.
---
## Step 5: Initialize Build Environment
```bash
cd $MIRROR_BASE/sources/poky-scarthgap
# Source the build environment
source oe-init-build-env ../build
# This creates the build directory and sets up environment
# You should now be in: ~/tqma6-yocto-mirror/build
``` ```
--- ---
## Step 6: Configure Build for TQMa6UL ## Step 4: First Build (Downloads All Sources)
### 6.1 Edit `conf/local.conf` This step downloads all required source packages for offline use:
```bash ```bash
# Edit the local.conf file cd ${UT_BASE}/ci-meta-tq
vim conf/local.conf
# Ensure environment is set
export MACHINE=tqma6ulx-mba6ulx
. ./setup-environment build_ut imx
# Build the image (downloads all sources)
bitbake tq-image-small-debug
# Alternative images:
# bitbake core-image-minimal
# bitbake core-image-full-cmdline
``` ```
**Add/modify these settings:** **Expected duration:** 4-8 hours (first build, depends on hardware)
```conf
# Machine selection for TQMa6UL on MBa6x
MACHINE ??= "tqma6ulx-mba6ulx"
# Parallelism (adjust to your CPU)
BB_NUMBER_THREADS ?= "8"
PARALLEL_MAKE ?= "-j8"
# Download directory (for mirroring)
DL_DIR ?= "${MIRROR_BASE}/downloads"
# Shared state cache
SSTATE_DIR ?= "${MIRROR_BASE}/sstate-cache"
# Keep source code for license compliance
RM_WORK_EXCLUDE += "*"
INHERIT += "archiver"
ARCHIVER_MODE[src] = "original"
ARCHIVER_MODE[diff] = "1"
# Generate license information
COPY_LIC_MANIFEST = "1"
COPY_LIC_DIRS = "1"
# Create source mirror
INHERIT += "own-mirrors"
SOURCE_MIRROR_URL ?= "file://${MIRROR_BASE}/mirror/"
BB_GENERATE_MIRROR_TARBALLS = "1"
```
### 6.2 Add Layers to `conf/bblayers.conf`
```bash
vim conf/bblayers.conf
```
**Content:**
```conf
BBLAYERS ?= " \
${MIRROR_BASE}/sources/poky-scarthgap/meta \
${MIRROR_BASE}/sources/poky-scarthgap/meta-poky \
${MIRROR_BASE}/sources/poky-scarthgap/meta-yocto-bsp \
${MIRROR_BASE}/sources/meta-openembedded/meta-oe \
${MIRROR_BASE}/sources/meta-openembedded/meta-python \
${MIRROR_BASE}/sources/meta-openembedded/meta-networking \
${MIRROR_BASE}/sources/meta-openembedded/meta-filesystems \
${MIRROR_BASE}/sources/meta-tq/meta-tq \
"
```
---
## Step 7: First Build (Downloads All Sources)
```bash
# Still in build directory
# This will download all required source packages
bitbake core-image-minimal
```
**Expected duration:** 2-6 hours (first build, depending on hardware)
**What happens:** **What happens:**
1. BitBake parses all recipes 1. BitBake parses all recipes from all layers
2. Downloads source code for every package 2. Downloads source code for every package to `/srv/yocto/downloads`
3. Builds toolchain, kernel, rootfs 3. Populates shared state cache in `/srv/yocto/sstate-cache`
4. Creates deployment images 4. Builds toolchain, kernel, bootloader, rootfs
5. Creates deployment images in `build_ut/tmp/deploy/images/`
--- ---
## Step 8: Create Source Mirror ## Step 5: Create Source Mirror for Air-Gap
### 8.1 Generate Mirror Tarballs ### 5.1 Configure Premirror
Add premirror configuration to site.conf:
```bash ```bash
# Create mirror directory cat >> ~/.yocto/site.conf <<'EOF'
mkdir -p ${MIRROR_BASE}/mirror
# Copy downloaded sources # --- Offline / Premirror Setup ---
cp -r ${MIRROR_BASE}/downloads/* ${MIRROR_BASE}/mirror/ 2>/dev/null || true # These settings enable offline builds after mirror creation
# Create source archive with archiver SOURCE_MIRROR_URL ?= "file:///srv/yocto/premirror/"
bitbake core-image-minimal -c do_populate_lic INHERIT += "own-mirrors"
PREMIRRORS:prepend = " \
git://.*/.* file:///srv/yocto/premirror/ \n \
ftp://.*/.* file:///srv/yocto/premirror/ \n \
http://.*/.* file:///srv/yocto/premirror/ \n \
https://.*/.* file:///srv/yocto/premirror/ \n \
"
EOF
# Create premirror directory
sudo mkdir -p /srv/yocto/premirror
sudo chown -R "$USER:$USER" /srv/yocto
``` ```
### 8.2 Collect License Information ### 5.2 Fill Mirror with ci-meta-tq Script
Use TQ's provided script to populate the mirror:
```bash ```bash
cd ${UT_BASE}/ci-meta-tq
# Set machine and config
export MACHINE=tqma6ulx-mba6ulx
# Fill mirror (downloads all git repos and tarballs)
ci/fill_mirror build_ut imx
# Verify mirror contents
ls -la /srv/yocto/premirror/
du -sh /srv/yocto/premirror/
du -sh /srv/yocto/downloads/
du -sh /srv/yocto/sstate-cache/
```
### 5.3 Generate License Information
```bash
cd ${UT_BASE}/ci-meta-tq
. ./setup-environment build_ut imx
# Generate license manifest # Generate license manifest
bitbake core-image-minimal -c do_populate_lic bitbake tq-image-small-debug -c do_populate_lic
# Copy license files # Copy license files
mkdir -p ${MIRROR_BASE}/licenses mkdir -p ${UT_BASE}/mirror-bundle/licenses
cp -r ${MIRROR_BASE}/build/tmp/deploy/licenses/* ${MIRROR_BASE}/licenses/ cp -r build_ut/tmp/deploy/licenses/* ${UT_BASE}/mirror-bundle/licenses/
# Create license CSV (see separate script) # Create license table (see separate script)
``` ```

## Step 10: Generate License Table ## Step 7: Generate License Table
**See:** [License Table Generation Script](../03-license-analysis/generate-license-table.sh) ### 7.1 Create License CSV
The license table must include: ```bash
- Package name cd ${UT_BASE}
- Version
- License (SPDX identifier) # Generate from BitBake license manifest
- License file location cat > generate-license-table.sh <<'SCRIPT'
- Source location #!/bin/bash
- Military use approval (Yes/No/Conditional) # Generate license table for software approval
OUTPUT="UT-license-table.csv"
echo "Package,Version,Recipe,License,MilitaryUse,SourceLocation,Notes" > $OUTPUT
# Process license manifest
find build_ut/tmp/deploy/licenses -name "*.csv" -o -name "*.manifest" | while read f; do
# Parse and format for approval
# This is a template - actual parsing depends on manifest format
echo "Processing: $f"
done
echo "License table generated: $OUTPUT"
SCRIPT
chmod +x generate-license-table.sh
```
### 7.2 Manual License Review

## Troubleshooting ## Deliverables for Software Approval
### Problem: Fetch failures during build 1. **UT-mirror-package.tar.gz** - Complete source mirror
2. **UT-license-table.csv** - License compliance table
**Solution:** Check internet connectivity, proxy settings. Some corporate networks block git:// protocol: 3. **SHA256 checksums** - Integrity verification
```bash 4. **Build instructions** - Corporate deployment guide
git config --global url."https://".insteadOf git:// 5. **2038-compliance-doc** - Analysis document
```
### Problem: Disk space exhausted
**Solution:** Ensure at least 100GB free. Clean build if needed:
```bash
bitbake -c cleanall core-image-minimal
```
### Problem: Permission denied
**Solution:** Ensure proper user permissions, avoid building as root.

# Setup downloads directory (offline) # Copy downloads
mkdir -p downloads cp -r downloads/* /srv/yocto/downloads/
cp -r mirror-package/downloads/* downloads/ 2>/dev/null || true
```
### 3.2 Initialize Build # SState cache (optional, speeds up rebuilds)
cp -r sstate-cache/* /srv/yocto/sstate-cache/ 2>/dev/null || true
```bash
# Source the build environment
cd ${CORP_BASE}/poky-scarthgap
source oe-init-build-env ${CORP_BASE}/build
# You are now in ${CORP_BASE}/build
```
### 3.3 Configure for Offline Build
Edit `${CORP_BASE}/build/conf/local.conf`:
```conf
