## Overview
|
||||||
|
|
||||||
|
This project addresses the requirement to migrate from legacy PTXdist-based BSP to Yocto Project for TQMa6UL hardware. The primary driver is Year 2038 compliance for military/long-term deployments.
|
||||||
|
|
||||||
|
### 2038 Problem Context
|
||||||
|
|
||||||
|
The Year 2038 Problem (Y2K38) affects 32-bit systems using signed 32-bit time_t:
|
||||||
|
- Maximum representable time: 03:14:07 UTC on 19 January 2038
|
||||||
|
- Systems will overflow and behave unpredictably after this date
|
||||||
|
- Critical for military/aerospace systems with 15+ year service life
|
||||||
|
|
||||||
|
### Solution: Yocto Scarthgap (5.0 LTS)
|
||||||
|
|
||||||
|
**Key Features:**
|
||||||
|
- 64-bit time_t by default on 32-bit ARM (glibc 2.38+)
|
||||||
|
- Linux Kernel 6.6 LTS (includes CONFIG_COMPAT_32BIT_TIME)
|
||||||
|
- Long-term support until April 2028 (extendable)
|
||||||
|
- Full source availability for audit
|
||||||
|
|
||||||
|

# Year 2038 Problem Analysis for TQMa6UL
|
||||||
|
|
||||||
|
**Document ID:** ANA-2038-001
|
||||||
|
**Date:** 2026-03-01
|
||||||
|
**Author:** Siggi ⚙️
|
||||||
|
**Status:** Approved for Implementation
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Executive Summary
|
||||||
|
|
||||||
|
The TQMa6UL (NXP i.MX6 UltraLite) is a 32-bit ARM Cortex-A7 processor. Without proper software stack, it will be affected by the Year 2038 Problem. **Yocto Scarthgap (5.0) provides a complete solution** with 64-bit time_t support on 32-bit architectures.
|
||||||
|
|
||||||
|
**Recommendation:** Migrate from legacy PTXdist BSP to Yocto Scarthgap immediately.
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## 1. The Year 2038 Problem Explained
|
||||||
|
|
||||||
|
### 1.1 Technical Background
|
||||||
|
|
||||||
|
Unix-based systems traditionally use a signed 32-bit integer (`time_t`) to represent time:
|
||||||
|
- Counts seconds since January 1, 1970 (Unix Epoch)
|
||||||
|
- Maximum value: 2,147,483,647 (2³¹ - 1)
|
||||||
|
- **Critical date:** 03:14:07 UTC on 19 January 2038
|
||||||
|
|
||||||
|
After this date, the counter overflows to -2,147,483,648, causing:
|
||||||
|
- System time jumps to 13 December 1901
|
||||||
|
- Software crashes or undefined behavior
|
||||||
|
- File timestamps corrupted
|
||||||
|
- Security certificates invalid
|
||||||
|
- Scheduled tasks fail
|
||||||
|
|
||||||
|
### 1.2 Impact on 32-bit ARM Systems
|
||||||
|
|
||||||
|
The i.MX6 UltraLite (Cortex-A7) is a 32-bit processor:
|
||||||
|
- Cannot natively execute 64-bit instructions
|
||||||
|
- Requires software-level solution for 64-bit time
|
||||||
|
- Kernel, glibc, and all user-space libraries must be 2038-compliant
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 2. Solution: 64-bit time_t on 32-bit ARM
|
||||||
|
|
||||||
|
### 2.1 Three-Layer Solution Required
|
||||||
|
|
||||||
|
```
|
||||||
|
┌─────────────────────────────────────┐
|
||||||
|
│ User Space Applications │
|
||||||
|
│ → Compiled with 64-bit time_t │
|
||||||
|
├─────────────────────────────────────┤
|
||||||
|
│ C Library (glibc) │
|
||||||
|
│ → glibc 2.34+ with 64-bit time_t │
|
||||||
|
├─────────────────────────────────────┤
|
||||||
|
│ Linux Kernel │
|
||||||
|
│ → 5.1+ with CONFIG_TIME_LOW_RES │
|
||||||
|
│ → 5.6+ with complete y2038 syscalls│
|
||||||
|
└─────────────────────────────────────┘
|
||||||
|
```
|
||||||
|
|
||||||
|
### 2.2 Yocto Scarthgap (5.0) Compliance
|
||||||
|
|
||||||
|
Yocto Project 5.0 (Scarthgap) released April 2024 provides:
|
||||||
|
|
||||||
|
| Component | Version | 2038 Feature | Status |
|
||||||
|
|-----------|---------|--------------|--------|
|
||||||
|
| **glibc** | 2.38+ | 64-bit `time_t` default on 32-bit | ✅ |
|
||||||
|
| **Linux Kernel** | 6.6 LTS | `CONFIG_COMPAT_32BIT_TIME` | ✅ |
|
||||||
|
| **GCC** | 13.x | Supports 64-bit time_t | ✅ |
|
||||||
|
| **BitBake** | 2.6 | Build system support | ✅ |
|
||||||
|
|
||||||
|
**Critical:** glibc 2.34+ uses 64-bit `time_t` BY DEFAULT for 32-bit ARM in Yocto.
|
||||||
|
|
||||||

|
||||||
|
|
||||||
|
## 3. TQ BSP Scarthgap Analysis
|
||||||
|
|
||||||
|
### 3.1 TQ BSP Version Information
|
||||||
|
|
||||||
|
**BSP Version:** `scarthgap.TQ.ARM.BSP.0006`
|
||||||
|
|
||||||
|
From TQ documentation:
|
||||||
|
| Component | Version | 2038 Status |
|
||||||
|
|-----------|---------|-------------|
|
||||||
|
| Linux Kernel | 6.6.y (LTS) | ✅ CONFIG_COMPAT_32BIT_TIME |
|
||||||
|
| U-Boot | 2023.10 | ✅ (no time-critical operations) |
|
||||||
|
| glibc | 2.38+ | ✅ 64-bit time_t |
|
||||||
|
|
||||||
|
### 3.2 Machine Configuration
|
||||||
|
|
||||||
|
For TQMa6UL-AB on MBa6x:
|
||||||
|
```
|
||||||
|
MACHINE = "tqma6ulx-mba6ulx"
|
||||||
|
```
|
||||||
|
|
||||||
|
Verified supported features with kernel 6.6:
|
||||||
|
- RTC (hardware clock) - 2038 compliant with 64-bit time
|
||||||
|
- Ethernet time stamping (PTP) - supported
|
||||||
|
- File systems (ext4, ubifs) - 2038 ready
|
||||||
|
|
||||||
|
### 3.3 Comparison with Legacy PTXdist
|
||||||
|
|
||||||
|
| Aspect | Old PTXdist BSP | Yocto Scarthgap | Impact |
|
||||||
|
|--------|-----------------|-----------------|--------|
|
||||||
|
| Kernel | 4.x or 5.4 | 6.6 LTS | Major upgrade |
|
||||||
|
| glibc | 2.31 or older | 2.38+ | **64-bit time_t** |
|
||||||
|
| time_t size | 32-bit | **64-bit** | **2038 compliant** |
|
||||||
|
| Support End | Already ended | April 2028+ | Extended life |
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 4. Verification Steps
|
||||||
|
|
||||||
|
### 4.1 Build-Time Verification
|
||||||
|
|
||||||
|
After building Yocto image, verify:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Check glibc time_t size
|
||||||
|
bitbake -e core-image-minimal | grep TIME_BITS
|
||||||
|
echo "TIME_BITS=64" # Expected output
|
||||||
|
|
||||||
|
# Check kernel config
|
||||||
|
bitbake -e virtual/kernel | grep CONFIG_COMPAT_32BIT_TIME
|
||||||
|
# Should be "y"
|
||||||
|
```
|
||||||
|
|
||||||
|
### 4.2 Runtime Verification
|
||||||
|
|
||||||
|
On target system:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Check time_t size in compiled binaries
|
||||||
|
echo '#include <time.h>' | gcc -x c - -dM -E | grep TIME_BITS
|
||||||
|
#define __TIME_BITS 64
|
||||||
|
|
||||||
|
# Test with date command (requires setting date beyond 2038)
|
||||||
|
date -s "2039-01-01 12:00:00"
|
||||||
|
date # Should display correctly
|
||||||
|
```
|
||||||
|
|
||||||
|
### 4.3 Static Analysis
|
||||||
|
|
||||||
|
Check for 2038-sensitive APIs:
|
||||||
|
```bash
|
||||||
|
# Scan for deprecated time functions
|
||||||
|
grep -r "time_t\|gettimeofday\|stime" ${IMAGE_ROOTFS}/usr/bin/
|
||||||
|
```
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## 5. Risk Assessment
|
||||||
|
|
||||||
|

|
||||||
|
| System failure after 2038 | Certain | Critical | None possible |
|
||||||
|
| Security certificate issues | High | High | None possible |
|
||||||
|
| Log corruption | Certain | Medium | None possible |
|
||||||
|
| **Overall Risk** | **CRITICAL** | | **Immediate action required** |
|
||||||
|
|
||||||
|
### 5.2 With Migration (Yocto Scarthgap)
|
||||||
|
|
||||||
|
| Risk | Probability | Impact | Mitigation |
|
||||||
|
|------|-------------|--------|------------|
|
||||||
|
| 2038 compliance | Near-zero | None | Full support until 2106+ |
|
||||||
|
| Migration effort | Medium | Medium | Documented procedure |
|
||||||
|
| Testing required | Certain | Low | Comprehensive test plan |
|
||||||
|
| **Overall Risk** | **LOW** | | **Recommended path** |
|
||||||

## Step 4: Clone TQ BSP Layer
|
||||||
|
|
||||||
|
```bash
|
||||||
|
cd $MIRROR_BASE/sources
|
||||||
|
|

|
||||||
|
|
||||||
|
## Step 5: Initialize Build Environment
|
||||||
|
|
||||||
|
```bash
|
||||||
|
cd $MIRROR_BASE/sources/poky-scarthgap
|
||||||
|
|
||||||
|
# Source the build environment
|
||||||
|
source oe-init-build-env ../build
|
||||||
|
|
||||||
|
# This creates the build directory and sets up environment
|
||||||
|
# You should now be in: ~/tqma6-yocto-mirror/build
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Step 6: Configure Build for TQMa6UL
|
||||||
|
|
||||||
|
### 6.1 Edit `conf/local.conf`
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Edit the local.conf file
|
||||||
|
vim conf/local.conf
|
||||||
|
```
|
||||||
|
|
||||||
|
**Add/modify these settings:**
|
||||||
|
|
||||||
|
```conf
|
||||||
|
# Machine selection for TQMa6UL on MBa6x
|
||||||
|
MACHINE ??= "tqma6ulx-mba6ulx"
|
||||||
|
|
||||||
|
# Parallelism (adjust to your CPU)
|
||||||
|
BB_NUMBER_THREADS ?= "8"
|
||||||
|
PARALLEL_MAKE ?= "-j8"
|
||||||
|
|
||||||
|
# Download directory (for mirroring)
|
||||||
|
DL_DIR ?= "${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:**
|
||||||
|
1. BitBake parses all recipes
|
||||||
|
2. Downloads source code for every package
|
||||||
|
3. Builds toolchain, kernel, rootfs
|
||||||
|
4. Creates deployment images
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## Step 8: Create Source Mirror
|
||||||
|
|
||||||
|
### 8.1 Generate Mirror Tarballs
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Create mirror directory
|
||||||
|
mkdir -p ${MIRROR_BASE}/mirror
|
||||||
|
|
||||||
|
# Copy downloaded sources
|
||||||
|
cp -r ${MIRROR_BASE}/downloads/* ${MIRROR_BASE}/mirror/ 2>/dev/null || true
|
||||||
|
|
||||||
|
# Create source archive with archiver
|
||||||
|
bitbake core-image-minimal -c do_populate_lic
|
||||||
|
```
|
||||||
|
|
||||||
|
### 8.2 Collect License Information
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Generate license manifest
|
||||||
|
bitbake core-image-minimal -c do_populate_lic
|
||||||
|
|
||||||
|
# Copy license files
|
||||||
|
mkdir -p ${MIRROR_BASE}/licenses
|
||||||
|
cp -r ${MIRROR_BASE}/build/tmp/deploy/licenses/* ${MIRROR_BASE}/licenses/
|
||||||
|
|
||||||
|
# Create license CSV (see separate script)
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Step 9: Package the Mirror
|
||||||
|
|
||||||
|
### 9.1 Create Archive Structure
|
||||||
|
|
||||||
|
```bash
|
||||||
|
cd ${MIRROR_BASE}
|
||||||
|
|
||||||
|
# Create organized structure for approval
|
||||||
|
mkdir -p mirror-package/{sources,licenses,build-instructions}
|
||||||
|
|
||||||
|
# Copy source layers (git repositories)
|
||||||
|
cp -r sources/* mirror-package/sources/
|
||||||
|
|
||||||
|
# Copy license information
|
||||||
|
cp -r licenses/* mirror-package/licenses/ 2>/dev/null || true
|
||||||
|
|
||||||
|
# Copy downloads (source tarballs)
|
||||||
|
mkdir -p mirror-package/downloads
|
||||||
|
cp -r downloads/* mirror-package/downloads/ 2>/dev/null || true
|
||||||
|
|
||||||
|
# Document the configuration
|
||||||
|
cp build/conf/local.conf mirror-package/build-instructions/
|
||||||
|
cp build/conf/bblayers.conf mirror-package/build-instructions/
|
||||||
|
```
|
||||||
|
|
||||||
|
### 9.2 Create Archive
|
||||||
|
|
||||||
|
```bash
|
||||||
|
cd ${MIRROR_BASE}
|
||||||
|
|
||||||
|
# Create timestamped archive
|
||||||
|
export TIMESTAMP=$(date +%Y%m%d-%H%M%S)
|
||||||
|
export ARCHIVE_NAME="tqma6-yocto-mirror-scarthgap-${TIMESTAMP}.tar.gz"
|
||||||
|
|
||||||
|
tar czf ${ARCHIVE_NAME} \
|
||||||
|
--exclude='.git/objects/pack/*' \
|
||||||
|
mirror-package/
|
||||||
|
|
||||||
|
# Calculate checksum
|
||||||
|
sha256sum ${ARCHIVE_NAME} > ${ARCHIVE_NAME}.sha256
|
||||||
|
|
||||||
|
echo "Archive created: ${ARCHIVE_NAME}"
|
||||||
|
echo "Size: $(du -h ${ARCHIVE_NAME} | cut -f1)"
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Step 10: Generate License Table
|
||||||
|
|
||||||
|
**See:** [License Table Generation Script](../03-license-analysis/generate-license-table.sh)
|
||||||
|
|
||||||
|
The license table must include:
|
||||||
|
- Package name
|
||||||
|
- Version
|
||||||
|
- License (SPDX identifier)
|
||||||
|
- License file location
|
||||||
|
- Source location
|
||||||
|
- Military use approval (Yes/No/Conditional)
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## Verification Checklist
|
||||||
|
|
||||||
|
Before delivering mirror:
|
||||||
|
|
||||||
|
- [ ] All git repositories cloned (poky, meta-openembedded, meta-tq)
|
||||||
|
- [ ] Complete source downloads in `downloads/` directory
|
||||||
|
- [ ] Build successful: `core-image-minimal` completed
|
||||||
|
- [ ] License information generated in `licenses/`
|
||||||
|
- [ ] Archive created with timestamp
|
||||||
|
- [ ] SHA256 checksum calculated
|
||||||
|
- [ ] License compliance table generated
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## Troubleshooting
|
||||||
|
|
||||||
|
### Problem: Fetch failures during build
|
||||||
|
|
||||||
|
**Solution:** Check internet connectivity, proxy settings. Some corporate networks block git:// protocol:
|
||||||
|
```bash
|
||||||
|
git config --global url."https://".insteadOf git://
|
||||||
|
```
|
||||||
|
|
||||||
|
### 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.
|
||||||
|
|
||||||

|
||||||
|
|
||||||
|
## Next Steps
|
||||||
|
|
||||||
|
1. **Transfer archive** to corporate network (USB, secure transfer)
|
||||||
|
2. **Submit for software approval** with license table
|
||||||
|
3. **Deploy in corporate environment** following [Deployment Guide](../04-deployment/corporate-network-deployment.md)

|
## Generating the Complete Table
|
||||||
|
|
||||||
|
### Method 1: Yocto Built-in
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# After successful build
|
||||||
|
cd ${MIRROR_BASE}/build
|
||||||
|
|
||||||
|
# Generate license manifest
|
||||||
|
bitbake core-image-minimal -c do_populate_lic
|
||||||
|
|
||||||
|
# Find license files
|
||||||
|
find tmp/deploy/licenses -name "license.manifest" -o -name "image_license.manifest"
|
||||||
|
|
||||||
|
# Copy for analysis
|
||||||
|
cp -r tmp/deploy/licenses ${MIRROR_BASE}/licenses/
|
||||||
|
```
|
||||||
|
|
||||||
|
### Method 2: Script-Based Extraction
|
||||||
|
|
||||||
|
```bash
|
||||||
|
#!/bin/bash
|
||||||
|
# generate-license-table.sh
|
||||||
|
|
||||||
|
OUTPUT="license-table.csv"
|
||||||
|
echo "Package,Version,License,Source,MilitaryUse" > $OUTPUT
|
||||||
|
|
||||||
|
cd ${MIRROR_BASE}/build/tmp/deploy/licenses
|
||||||
|
grep -r "LICENSE:" . | while read line; do
|
||||||
|
pkg=$(echo $line | cut -d: -f2)
|
||||||
|
lic=$(echo $line | cut -d: -f3)
|
||||||
|
# Add logic to determine military use
|
||||||
|
echo "$pkg,,$lic,,TBD" >> $OUTPUT
|
||||||
|
done
|
||||||
|
```
|
||||||
|
|
||||||
|
## Manual Review Required
|
||||||
|
|
||||||
|
### Packages to Flag for Review
|
||||||
|
|
||||||
|
1. **Firmware blobs** (WiFi, GPU, VPU)
|
||||||
|
- Location: `linux-firmware`, `firmware-imx`
|
||||||
|
- Often proprietary licenses
|
||||||
|
- May require separate approval
|
||||||
|
|
||||||
|
2. **Cryptographic software**
|
||||||
|
- OpenSSL, gnutls
|
||||||
|
- Check export control classifications
|
||||||
|
|
||||||
|
3. **Graphics drivers**
|
||||||
|
- Vivante GPU drivers (imx-gpu-viv)
|
||||||
|
- Proprietary binary blobs
|
||||||
|
|
||||||
|
4. **Documentation**
|
||||||
|
- CC-BY-SA licensed manuals
|
||||||
|
- Generally acceptable
|
||||||
|
|
||||||
|
## Military Use Approval Criteria
|
||||||
|
|
||||||
|
### Automatic Approval
|
||||||
|
- MIT, BSD, Apache-2.0: ✅ No restrictions
|
||||||
|
- GPL/LGPL: ✅ With source code provision
|
||||||
|
|
||||||
|
### Requires Legal Review
|
||||||
|
- GPL-3.0 with anti-tivoization
|
||||||
|
- Any proprietary license
|
||||||
|
- Custom/TQ-specific licenses
|
||||||
|
|
||||||
|
### Automatic Rejection
|
||||||
|
- No license information
|
||||||
|
- Proprietary binary-only
|
||||||
|
- Export-controlled encryption (without clearance)
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## Step 3: Setup Yocto Build Environment
|
||||||
|
|
||||||
|
### 3.1 Create Directory Structure
|
||||||
|
|
||||||
|
```bash
|
||||||
|
cd ${CORP_BASE}
|
||||||
|
|
||||||
|
# Create working directories
|
||||||
|
mkdir -p build
|
||||||
|
mkdir -p mirror
|
||||||
|
|
||||||
|
# Copy sources
|
||||||
|
cp -r mirror-package/sources/* ./
|
||||||
|
|
||||||
|
# Setup downloads directory (offline)
|
||||||
|
mkdir -p downloads
|
||||||
|
cp -r mirror-package/downloads/* downloads/ 2>/dev/null || true
|
||||||
|
```
|
||||||
|
|
||||||
|
### 3.2 Initialize Build
|
||||||
|
|
||||||
|
```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
|
||||||
|
# Machine selection
|
||||||
|
MACHINE ??= "tqma6ulx-mba6ulx"
|
||||||
|
|
||||||
|
# Offline/Premirror configuration
|
||||||
|
BB_NO_NETWORK = "1"
|
||||||
|
|
||||||
|
# Use local mirror for all sources
|
||||||
|
PREMIRRORS:prepend = " \
|
||||||
|
git://.*/.* file://${CORP_BASE}/downloads/ \
|
||||||
|
ftp://.*/.* file://${CORP_BASE}/downloads/ \
|
||||||
|
http://.*/.* file://${CORP_BASE}/downloads/ \
|
||||||
|
https://.*/.* file://${CORP_BASE}/downloads/ \
|
||||||
|
"
|
||||||
|
|
||||||
|
# Don't check for updates
|
||||||
|
BB_FETCH_PREMIRRORONLY = "1"
|
||||||
|
|
||||||
|
# Parallelism
|
||||||
|
BB_NUMBER_THREADS ?= "8"
|
||||||
|
PARALLEL_MAKE ?= "-j8"
|
||||||
|
|
||||||
|
# DL directory
|
||||||
|
DL_DIR = "${CORP_BASE}/downloads"
|
||||||
|
|
||||||
|
# SSTATE (optional, for faster rebuilds)
|
||||||
|
SSTATE_DIR = "${CORP_BASE}/sstate-cache"
|
||||||
|
|
||||||
|
# Archive settings for compliance
|
||||||
|
INHERIT += "archiver"
|
||||||
|
ARCHIVER_MODE[src] = "original"
|
||||||
|
COPY_LIC_MANIFEST = "1"
|
||||||
|
COPY_LIC_DIRS = "1"
|
||||||
|
```
|
||||||
|
|
||||||
|
### 3.4 Configure Layers
|
||||||
|
|
||||||
|
Edit `${CORP_BASE}/build/conf/bblayers.conf`:
|
||||||
|
|
||||||
|
```conf
|
||||||
|
BBLAYERS ?= " \
|
||||||
|
${CORP_BASE}/poky-scarthgap/meta \
|
||||||
|
${CORP_BASE}/poky-scarthgap/meta-poky \
|
||||||
|
${CORP_BASE}/poky-scarthgap/meta-yocto-bsp \
|
||||||
|
${CORP_BASE}/meta-openembedded/meta-oe \
|
||||||
|
${CORP_BASE}/meta-openembedded/meta-python \
|
||||||
|
${CORP_BASE}/meta-openembedded/meta-networking \
|
||||||
|
${CORP_BASE}/meta-openembedded/meta-filesystems \
|
||||||
|
${CORP_BASE}/meta-tq/meta-tq \
|
||||||
|
"
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Step 4: Build Image
|
||||||
|
|
||||||
|
### 4.1 First Build (Offline)
|
||||||
|
|
||||||
|
```bash
|
||||||
|
cd ${CORP_BASE}/build
|
||||||
|
|
||||||
|
# Ensure we're in the build environment
|
||||||
|
source ${CORP_BASE}/poky-scarthgap/oe-init-build-env ${CORP_BASE}/build
|
||||||
|
|
||||||
|
# Start build (all sources should be local)
|
||||||
|
bitbake core-image-minimal
|
||||||
|
```
|
||||||
|
|
||||||
|
**Expected:** Build completes without network access.
|
||||||
|
|
||||||
|
### 4.2 Verify 2038 Compliance
|
||||||
|
|
||||||
|
After successful build:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Check time_t size in generated toolchain
|
||||||
|
${CORP_BASE}/build/tmp/sysroots/x86_64-linux/usr/bin/arm-poky-linux-gnueabi-gcc -dM -E - < /dev/null | grep TIME_BITS
|
||||||
|
# Expected: #define __TIME_BITS 64
|
||||||
|
|
||||||
|
# Check kernel config
|
||||||
|
bitbake -e virtual/kernel | grep CONFIG_COMPAT_32BIT_TIME
|
||||||
|
# Expected: CONFIG_COMPAT_32BIT_TIME=y
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Step 5: Development Workflow
|
||||||
|
|
||||||
|
### 5.1 Daily Use
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Enter build environment
|
||||||
|
cd ${CORP_BASE}
|
||||||
|
source poky-scarthgap/oe-init-build-env build
|
||||||
|
|
||||||
|
# Build target
|
||||||
|
bitbake core-image-minimal
|
||||||
|
|
||||||
|
# Deploy to target (SD card / eMMC)
|
||||||
|
# See TQ documentation for deployment methods
|
||||||
|
```
|
||||||
|
|
||||||
|
### 5.2 Adding Custom Layers
|
||||||
|
|
||||||
|
If custom corporate layers are required:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Add to bblayers.conf
|
||||||
|
vim ${CORP_BASE}/build/conf/bblayers.conf
|
||||||
|
|
||||||
|
# Add path to custom layer
|
||||||
|
# ${CORP_BASE}/meta-custom \
|
||||||
|
```
|
||||||
|
|
||||||
|
### 5.3 SDK Generation
|
||||||
|
|
||||||
|
For application development:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Generate SDK
|
||||||
|
bitbake core-image-minimal -c populate_sdk
|
||||||
|
|
||||||
|
# Install SDK
|
||||||
|
${CORP_BASE}/build/tmp/deploy/sdk/*.sh
|
||||||
|
|
||||||
|
# Source SDK environment
|
||||||
|
source /opt/poky/.../environment-setup-arm-poky-linux-gnueabi
|
||||||
|
```
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## Maintenance
|
||||||
|
|
||||||
|
### Updating the Mirror
|
||||||
|
|
||||||
|
When new TQ BSP versions are approved:
|
||||||
|
|
||||||
|
1. Request updated mirror from external system
|
||||||
|
2. Verify checksums
|
||||||
|
3. Extract to separate directory
|
||||||
|
4. Compare with current deployment
|
||||||
|
5. Test build in isolation
|
||||||
|
6. Switch over after validation
|
||||||
|
|
||||||
|
### Build Cache Management
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Clean build (keep downloads)
|
||||||
|
bitbake -c cleanall core-image-minimal
|
||||||
|
|
||||||
|
# Full clean (careful!)
|
||||||
|
rm -rf ${CORP_BASE}/build/tmp/
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Troubleshooting
|
||||||
|
|
||||||
|
### Issue: Network timeout errors
|
||||||
|
|
||||||
|
**Cause:** BitBake trying to fetch from internet
|
||||||
|
|
||||||
|
**Solution:**
|
||||||
|
```bash
|
||||||
|
# Verify BB_NO_NETWORK is set
|
||||||
|
grep BB_NO_NETWORK ${CORP_BASE}/build/conf/local.conf
|
||||||
|
|
||||||
|
# Should show: BB_NO_NETWORK = "1"
|
||||||
|
```
|
||||||
|
|
||||||
|
### Issue: Missing source files
|
||||||
|
|
||||||
|
**Cause:** Incomplete mirror transfer
|
||||||
|
|
||||||
|
**Solution:**
|
||||||
|
```bash
|
||||||
|
# Check downloads directory
|
||||||
|
ls ${CORP_BASE}/downloads | wc -l
|
||||||
|
# Compare with external mirror
|
||||||
|
|
||||||
|
# Re-transfer missing files
|
||||||
|
```
|
||||||
|
|
||||||
|
### Issue: Permission denied
|
||||||
|
|
||||||
|
**Solution:**
|
||||||
|
```bash
|
||||||
|
# Fix ownership
|
||||||
|
sudo chown -R $(whoami):$(whoami) ${CORP_BASE}
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Security Considerations
|
||||||
|
|
||||||
|
1. **No Internet Access:** Build must complete without network
|
||||||
|
2. **Audit Trail:** All sources archived and version-controlled
|
||||||
|
3. **License Compliance:** License manifest generated for every build
|
||||||
|
4. **User Permissions:** Build as regular user, not root
|
||||||
|
|
||||||
