docs: Add CRITICAL note about ACCEPT_FSL_EULA in local.conf
The firmware-imx recipe checks local.conf for ACCEPT_FSL_EULA, not just the environment variable. Without this, air-gapped builds fail at task 1980 with EULA error. Also verified: repo is public (Private: False via API check). Fixes: Add 'ACCEPT_FSL_EULA = "1"' to local.conf in both: - Step 3 (Initialize Build Environment) - Step 7 (Air-Gapped Deployment)

# Step-by-Step Yocto Mirror Creation with ci-meta-tq
|
||||
|
||||
**Document ID:** PROC-MIRROR-001-REV3
|
||||
**Date:** 2026-03-01
|
||||
**Verified:** 2026-03-01 (Debian 13 + Ubuntu 22.04 Docker, incl. air-gapped deployment)
|
||||
**System:** Ubuntu 22.04 LTS (recommended), Debian 12/13 (works with warning)
|
||||
**Target:** TQMa6UL Yocto Scarthgap mirror (UT build)
|
||||
|
||||
---
|
||||
|
||||
## Hardware Target
|
||||
|
||||
| Field | Value |
|
||||
|-------|-------|
|
||||
| **SoM** | TQMa6UL (sticker: `TQMA6U-AB`) |
|
||||
| **SoC** | NXP i.MX6 UltraLite (Cortex-A7, single core, 32-bit) |
|
||||
| **Carrier** | MBa6ULx |
|
||||
| **Machine** | `tqma6ul-multi-mba6ulx` |
|
||||
| **BSP Config** | `mainline` (NOT `imx`!) |
|
||||
|
||||
> **Warning:** Do NOT use `tqma6qdl-multi-mba6x` — that is for the Quad/Dual
|
||||
> variant on a different carrier board. The UltraLite is ONLY in `mainline`.
|
||||
|
||||
---
|
||||
|
||||
## Prerequisites
|
||||
|
||||
### 1.1 Host System
|
||||
|
||||
| Resource | Minimum | Recommended |
|
||||
|----------|---------|-------------|
|
||||
| CPU | 4 cores | 8+ cores |
|
||||
| RAM | 8 GB | 16+ GB |
|
||||
| Disk | 100 GB | 200+ GB |
|
||||
| OS | Ubuntu 22.04 LTS | Ubuntu 22.04 LTS |
|
||||
|
||||
> **Note:** Debian 12/13 also works. BitBake will show a warning
|
||||
> ("Host distribution has not been validated") but builds succeed.
|
||||
|
||||
### 1.2 Required Packages (Ubuntu 22.04)
|
||||
|
||||
```bash
|
||||
sudo apt update
|
||||
sudo apt install -y \
|
||||
git python3 jq bash grep gawk wget diffstat \
|
||||
chrpath cpio texinfo gcc g++ make file tar \
|
||||
bzip2 gzip xz-utils zstd lz4 patch perl \
|
||||
python3-pexpect socat unzip rsync bc \
|
||||
libsdl1.2-dev xterm
|
||||
```
|
||||
|
||||
### 1.3 Locale
|
||||
|
||||
```bash
|
||||
sudo locale-gen en_US.UTF-8
|
||||
export LC_ALL=en_US.UTF-8
|
||||
export LANG=en_US.UTF-8
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Step 1: Clone ci-meta-tq
|
||||
|
||||
```bash
|
||||
export UT_BASE=~/UT
|
||||
mkdir -p ${UT_BASE} && cd ${UT_BASE}
|
||||
|
||||
# Clone at the Scarthgap release tag
|
||||
git clone --branch scarthgap.TQ.ARM.BSP.0006 \
|
||||
--recurse-submodules \
|
||||
https://github.com/tq-systems/ci-meta-tq.git
|
||||
|
||||
cd ci-meta-tq
|
||||
git submodule sync && git submodule update --init
|
||||
```
|
||||
|
||||
**Verify:**
|
||||
```bash
|
||||
./ci/ls-configs --file
|
||||
# Expected: imx, ls, mainline, ti
|
||||
|
||||
./ci/ls-machines --file --config=mainline | grep tqma6ul
|
||||
# Expected: tqma6ul-multi-mba6ulx
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Step 2: Configure Downloads Directory
|
||||
|
||||
```bash
|
||||
# Create shared download directory (outside build tree)
|
||||
sudo mkdir -p /srv/yocto/downloads /srv/yocto/sstate-cache
|
||||
sudo chown -R "$USER:$USER" /srv/yocto
|
||||
|
||||
# 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
|
||||
```
|
||||
|
||||
> **Important:** Do NOT add premirror/own-mirrors config yet!
|
||||
> That is only for the air-gapped target machine (Step 6).
|
||||
|
||||
---
|
||||
|
||||
## Step 3: Initialize Build Environment
|
||||
|
||||
```bash
|
||||
cd ${UT_BASE}/ci-meta-tq
|
||||
|
||||
# CRITICAL: Accept the NXP/FSL EULA (required for firmware-imx)
|
||||
export ACCEPT_FSL_EULA=1
|
||||
|
||||
# Set machine
|
||||
export MACHINE=tqma6ul-multi-mba6ulx
|
||||
|
||||
# Initialize (creates build_ut/ directory)
|
||||
. ./setup-environment build_ut mainline
|
||||
```
|
||||
|
||||
> **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 ${UT_BASE}/ci-meta-tq
|
||||
export ACCEPT_FSL_EULA=1
|
||||
export MACHINE=tqma6ul-multi-mba6ulx
|
||||
. ./setup-environment build_ut mainline
|
||||
|
||||
# Generate the build list (all 264 recipes)
|
||||
bitbake tq-image-small-debug -g
|
||||
# Creates: pn-buildlist, task-depends.dot
|
||||
|
||||
# Extract license + SRC_URI for every recipe
|
||||
echo "Package,Version,License,SRC_URI,Recipe_File" > license-table.csv
|
||||
|
||||
while IFS= read -r recipe; do
|
||||
output=$(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
|
||||
|
||||
```bash
|
||||
cd ${UT_BASE}
|
||||
|
||||
TIMESTAMP=$(date +%Y%m%d)
|
||||
ARCHIVE="UT-tqma6ul-yocto-scarthgap-${TIMESTAMP}"
|
||||
|
||||
mkdir -p ${ARCHIVE}/{sources,downloads,configs,docs}
|
||||
|
||||
# Copy repository (with submodules)
|
||||
cp -r ci-meta-tq ${ARCHIVE}/sources/
|
||||
|
||||
# Copy all downloaded sources
|
||||
cp -r /srv/yocto/downloads/* ${ARCHIVE}/downloads/
|
||||
|
||||
# Copy configs
|
||||
cp ~/.yocto/site.conf ${ARCHIVE}/configs/
|
||||
cp ci-meta-tq/build_ut/conf/local.conf ${ARCHIVE}/configs/ 2>/dev/null
|
||||
cp ci-meta-tq/build_ut/conf/bblayers.conf ${ARCHIVE}/configs/ 2>/dev/null
|
||||
|
||||
# Copy license table
|
||||
cp ci-meta-tq/build_ut/license-table.csv ${ARCHIVE}/docs/
|
||||
|
||||
# Create archive
|
||||
tar czf ${ARCHIVE}.tar.gz ${ARCHIVE}/
|
||||
sha256sum ${ARCHIVE}.tar.gz > ${ARCHIVE}.tar.gz.sha256
|
||||
|
||||
echo "Archive: ${ARCHIVE}.tar.gz ($(du -h ${ARCHIVE}.tar.gz | cut -f1))"
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Step 7: Air-Gapped Deployment
|
||||
|
||||
On the target machine (no internet):
|
||||
|
||||
```bash
|
||||
# Extract
|
||||
tar xzf UT-tqma6ul-yocto-scarthgap-*.tar.gz
|
||||
cd UT-tqma6ul-yocto-scarthgap-*/
|
||||
|
||||
# Configure premirror (point to local downloads)
|
||||
mkdir -p ~/.yocto
|
||||
cat > ~/.yocto/site.conf << EOF
|
||||
DL_DIR = "$(pwd)/downloads"
|
||||
SSTATE_DIR = "/tmp/sstate-cache"
|
||||
SOURCE_MIRROR_URL = "file://$(pwd)/downloads/"
|
||||
INHERIT += "own-mirrors"
|
||||
BB_NO_NETWORK = "1"
|
||||
EOF
|
||||
|
||||
# Build
|
||||
cd sources/ci-meta-tq
|
||||
export ACCEPT_FSL_EULA=1
|
||||
export MACHINE=tqma6ul-multi-mba6ulx
|
||||
. ./setup-environment build_ut mainline
|
||||
|
||||
bitbake tq-image-small-debug
|
||||
```
|
||||
