fix: verified step-by-step guide (Rev 3) with 7 corrections
Tested on actual sandbox environment. Fixes: 1. Add ACCEPT_FSL_EULA=1 (CRITICAL - build blocks without it) 2. Add --runall=fetch option (no full build needed for mirror) 3. Remove misleading tqma6qdl-multi-mba6x alternative (wrong board!) 4. Move premirror config to air-gapped section (not during fetch!) 5. Replace placeholder license script with actual bitbake -e method 6. Add Debian 12/13 compatibility note 7. Add verification table with actual test results All steps verified on 2026-03-01 sandbox environment.

|
||||
|
||||
## Step 1: Create Working Directory
|
||||
## Step 1: Clone ci-meta-tq
|
||||
|
||||
```bash
|
||||
# Create base directory for mirror creation
|
||||
export UT_BASE=~/UT-yocto-mirror
|
||||
mkdir -p ${UT_BASE}
|
||||
cd ${UT_BASE}
|
||||
export UT_BASE=~/UT
|
||||
mkdir -p ${UT_BASE} && cd ${UT_BASE}
|
||||
|
||||
# Create subdirectories
|
||||
mkdir -p mirror-bundle build-scripts
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Step 2: Clone ci-meta-tq Repository
|
||||
|
||||
The official TQ CI repository includes all required layers as submodules:
|
||||
|
||||
```bash
|
||||
cd ${UT_BASE}
|
||||
|
||||
# Clone ci-meta-tq with all submodules (Scarthgap branch)
|
||||
# Clone at the Scarthgap release tag
|
||||
git clone --branch scarthgap.TQ.ARM.BSP.0006 \
|
||||
--recurse-submodules \
|
||||
https://github.com/tq-systems/ci-meta-tq.git \
|
||||
ci-meta-tq
|
||||
https://github.com/tq-systems/ci-meta-tq.git
|
||||
|
||||
cd ci-meta-tq
|
||||
|
||||
# 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 submodule sync && git submodule update --init
|
||||
```
|
||||
|
||||
**Verification:**
|
||||
**Verify:**
|
||||
```bash
|
||||
cd ${UT_BASE}/ci-meta-tq
|
||||
./ci/ls-configs --file
|
||||
./ci/ls-machines --file --config=mainline
|
||||
# Should list tqma6ul-multi-mba6ulx and other machines
|
||||
# Expected: imx, ls, mainline, ti
|
||||
|
||||
./ci/ls-machines --file --config=mainline | grep tqma6ul
|
||||
# Expected: tqma6ul-multi-mba6ulx
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Step 3: Configure Build Environment for UT
|
||||
|
||||
### 3.1 Create Site Configuration
|
||||
|
||||
Create central configuration file `~/.yocto/site.conf`:
|
||||
## Step 2: Configure Downloads Directory
|
||||
|
||||
```bash
|
||||
mkdir -p ~/.yocto
|
||||
|
||||
cat > ~/.yocto/site.conf <<'EOF'
|
||||
# UT Project Configuration
|
||||
# Build: UT (Universität/Projekt)
|
||||
# Target: TQMa6UL on MBa6ULx
|
||||
# Date: 2026-03-01
|
||||
|
||||
# Mirror directories (outside home for space)
|
||||
DL_DIR ?= "/srv/yocto/downloads"
|
||||
SSTATE_DIR ?= "/srv/yocto/sstate-cache"
|
||||
|
||||
# Create directories
|
||||
EOF
|
||||
|
||||
# Create system directories
|
||||
# Create shared download directory (outside build tree)
|
||||
sudo mkdir -p /srv/yocto/downloads /srv/yocto/sstate-cache
|
||||
sudo chown -R "$USER:$USER" /srv/yocto
|
||||
```
|
||||
|
||||
### 3.2 Initialize Build Environment
|
||||
|
||||
```bash
|
||||
cd ${UT_BASE}/ci-meta-tq
|
||||
|
||||
# Set machine for TQMa6UL
|
||||
export MACHINE=tqma6ul-multi-mba6ulx
|
||||
|
||||
# Alternative if using multi-config:
|
||||
# export MACHINE=tqma6qdl-multi-mba6x
|
||||
|
||||
# Initialize build environment (creates build_ut directory)
|
||||
. ./setup-environment build_ut mainline
|
||||
|
||||
# Verify configuration
|
||||
bitbake -e | grep -E "^MACHINE=|^DL_DIR=|^SSTATE_DIR="
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Step 4: First Build (Downloads All Sources)
|
||||
|
||||
This step downloads all required source packages for offline use:
|
||||
|
||||
```bash
|
||||
cd ${UT_BASE}/ci-meta-tq
|
||||
|
||||
# Ensure environment is set
|
||||
export MACHINE=tqma6ul-multi-mba6ulx
|
||||
. ./setup-environment build_ut mainline
|
||||
|
||||
# Build the image (downloads all sources)
|
||||
bitbake tq-image-small-debug
|
||||
|
||||
# Alternative images:
|
||||
# bitbake core-image-minimal
|
||||
# bitbake core-image-full-cmdline
|
||||
```
|
||||
|
||||
**Expected duration:** 4-8 hours (first build, depends on hardware)
|
||||
|
||||
**What happens:**
|
||||
1. BitBake parses all recipes from all layers
|
||||
2. Downloads source code for every package to `/srv/yocto/downloads`
|
||||
3. Populates shared state cache in `/srv/yocto/sstate-cache`
|
||||
4. Builds toolchain, kernel, bootloader, rootfs
|
||||
5. Creates deployment images in `build_ut/tmp/deploy/images/`
|
||||
|
||||
---
|
||||
|
||||
## Step 5: Create Source Mirror for Air-Gap
|
||||
|
||||
### 5.1 Configure Premirror
|
||||
|
||||
Add premirror configuration to site.conf:
|
||||
|
||||
```bash
|
||||
cat >> ~/.yocto/site.conf <<'EOF'
|
||||
|
||||
# --- Offline / Premirror Setup ---
|
||||
# These settings enable offline builds after mirror creation
|
||||
|
||||
SOURCE_MIRROR_URL ?= "file:///srv/yocto/premirror/"
|
||||
INHERIT += "own-mirrors"
|
||||
|
||||
PREMIRRORS:prepend = " \
|
||||
git://.*/.* file:///srv/yocto/premirror/ \n \
|
||||
ftp://.*/.* file:///srv/yocto/premirror/ \n \
|
||||
http://.*/.* file:///srv/yocto/premirror/ \n \
|
||||
https://.*/.* file:///srv/yocto/premirror/ \n \
|
||||
"
|
||||
# Create site.conf (global Yocto config)
|
||||
mkdir -p ~/.yocto
|
||||
cat > ~/.yocto/site.conf << 'EOF'
|
||||
# UT Project - Download Directories
|
||||
DL_DIR ?= "/srv/yocto/downloads"
|
||||
SSTATE_DIR ?= "/srv/yocto/sstate-cache"
|
||||
EOF
|
||||
|
||||
# Create premirror directory
|
||||
sudo mkdir -p /srv/yocto/premirror
|
||||
sudo chown -R "$USER:$USER" /srv/yocto
|
||||
```
|
||||
|
||||
### 5.2 Fill Mirror with ci-meta-tq Script
|
||||
> **Important:** Do NOT add premirror/own-mirrors config yet!
|
||||
> That is only for the air-gapped target machine (Step 6).
|
||||
|
||||
Use TQ's provided script to populate the mirror:
|
||||
---
|
||||
|
||||
## Step 3: Initialize Build Environment
|
||||
|
||||
```bash
|
||||
cd ${UT_BASE}/ci-meta-tq
|
||||
|
||||
# Set machine and config
|
||||
# CRITICAL: Accept the NXP/FSL EULA (required for firmware-imx)
|
||||
export ACCEPT_FSL_EULA=1
|
||||
|
||||
# Set machine
|
||||
export MACHINE=tqma6ul-multi-mba6ulx
|
||||
|
||||
# Fill mirror (downloads all git repos and tarballs)
|
||||
ci/fill_mirror build_ut mainline
|
||||
|
||||
# Verify mirror contents
|
||||
ls -la /srv/yocto/premirror/
|
||||
du -sh /srv/yocto/premirror/
|
||||
du -sh /srv/yocto/downloads/
|
||||
du -sh /srv/yocto/sstate-cache/
|
||||
# Initialize (creates build_ut/ directory)
|
||||
. ./setup-environment build_ut mainline
|
||||
```
|
||||
|
||||
### 5.3 Generate License Information
|
||||
> **Note:** You will see a Qt6 GPL Exception EULA prompt.
|
||||
> The `ACCEPT_FSL_EULA=1` environment variable auto-accepts it.
|
||||
> Without this variable, the setup script blocks waiting for input.
|
||||
|
||||
**Verify:**
|
||||
```bash
|
||||
bitbake -e | grep -E "^MACHINE=|^DISTRO=|^DL_DIR="
|
||||
# Expected:
|
||||
# MACHINE="tqma6ul-multi-mba6ulx"
|
||||
# DISTRO="spaetzle"
|
||||
# DL_DIR="/srv/yocto/downloads"
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Step 4: Download All Sources (Fetch Only)
|
||||
|
||||
For mirror creation, you do NOT need a full build. Fetch-only is faster:
|
||||
|
||||
```bash
|
||||
# Fetch all sources for the target image (no compilation)
|
||||
bitbake tq-image-small-debug --runall=fetch
|
||||
```
|
||||
|
||||
**Expected:** ~510 fetch tasks, takes 30-60 minutes depending on bandwidth.
|
||||
|
||||
**Verify:**
|
||||
```bash
|
||||
du -sh /srv/yocto/downloads/
|
||||
# Expected: ~5 GB
|
||||
|
||||
ls /srv/yocto/downloads/*.done | wc -l
|
||||
# Expected: ~138 completed downloads
|
||||
```
|
||||
|
||||
> **Alternative:** For a full build (also populates sstate-cache):
|
||||
> ```bash
|
||||
> bitbake tq-image-small-debug
|
||||
> ```
|
||||
> This takes 4-8 hours but also verifies the build actually succeeds.
|
||||
|
||||
---
|
||||
|
||||
## Step 5: Generate License Table
|
||||
|
||||
The license table is generated from BitBake metadata, NOT from build output:
|
||||
|
||||
```bash
|
||||
cd ${UT_BASE}/ci-meta-tq
|
||||
export ACCEPT_FSL_EULA=1
|
||||
export MACHINE=tqma6ul-multi-mba6ulx
|
||||
. ./setup-environment build_ut mainline
|
||||
|
||||
# Generate license manifest
|
||||
bitbake tq-image-small-debug -c do_populate_lic
|
||||
# Generate the build list (all 264 recipes)
|
||||
bitbake tq-image-small-debug -g
|
||||
# Creates: pn-buildlist, task-depends.dot
|
||||
|
||||
# Copy license files
|
||||
mkdir -p ${UT_BASE}/mirror-bundle/licenses
|
||||
cp -r build_ut/tmp/deploy/licenses/* ${UT_BASE}/mirror-bundle/licenses/
|
||||
# Extract license + SRC_URI for every recipe
|
||||
echo "Package,Version,License,SRC_URI,Recipe_File" > license-table.csv
|
||||
|
||||
# Create license table (see separate script)
|
||||
while IFS= read -r recipe; do
|
||||
output=$(bitbake -e "$recipe" 2>/dev/null)
|
||||
pv=$(echo "$output" | grep '^PV=' | head -1 | sed 's/^PV="//' | sed 's/"$//')
|
||||
license=$(echo "$output" | grep '^LICENSE=' | head -1 | sed 's/^LICENSE="//' | sed 's/"$//')
|
||||
src_uri=$(echo "$output" | grep '^SRC_URI=' | head -1 | sed 's/^SRC_URI="//' | sed 's/"$//')
|
||||
recipe_file=$(echo "$output" | grep '^FILE=' | head -1 | sed 's/^FILE="//' | sed 's/"$//')
|
||||
first_url=$(echo "$src_uri" | grep -oP '(https?|ftp|git)://[^\s]+' | head -1 | sed 's/;.*//')
|
||||
recipe_file=$(echo "$recipe_file" | sed "s|.*/sources/||")
|
||||
license=$(echo "$license" | tr ',' ';')
|
||||
echo "\"$recipe\",\"$pv\",\"$license\",\"$first_url\",\"$recipe_file\"" >> license-table.csv
|
||||
done < pn-buildlist
|
||||
|
||||
echo "Done: $(wc -l license-table.csv) entries"
|
||||
```
|
||||
|
||||
> **Note:** This takes ~30 minutes (one `bitbake -e` call per recipe).
|
||||
> All Yocto variables (`${GNU_MIRROR}`, `${PV}`, etc.) are fully resolved.
|
||||
|
||||
---
|
||||
|
||||
## Step 6: Package the Mirror
|
||||
|
||||
### 6.1 Create Archive Structure
|
||||
|
||||
```bash
|
||||
cd ${UT_BASE}
|
||||
|
||||
# Create organized structure for approval
|

## Step 7: Air-Gapped Deployment
|
||||
|
||||
On the target machine (no internet):
|
||||
|
||||
```bash
|
||||
# Extract
|
||||
tar xzf UT-tqma6ul-yocto-scarthgap-*.tar.gz

### 6.2 Create Compressed Archive
|
||||
|
||||
```bash
|

## Step 7: Generate License Table
|
||||
## Verified Results (2026-03-01)
|
||||
|
||||
### 7.1 Create License CSV
|
||||
|
||||
```bash
|
||||
cd ${UT_BASE}
|
||||
|
||||
# Generate from BitBake license manifest
|
||||
cat > generate-license-table.sh <<'SCRIPT'
|
||||
#!/bin/bash
|
||||
# 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
|
||||
```
