📖 Legacy Radxa Images (2024-04 and earlier)

NOTE: This is relevant for images uploaded 2024-04 and earlier

At the time of writing (2024-04-01) the Radxa images for the Rock 3A and Zero 3W had a number of problems, namely:

• WiFi needs 2.4GHz WPA2 to work
• Locales and terminfo appear missing
• GL is 3.1 Mesa 20.3.5 by Mesa
• Based on Debian 11
• Kernel is 5.10
• Other annoyances such as packages I want not there

So I built an Armbian build using the Zero 3 WIP file, and it worked really well, thus I decided to share them. Using RKDevTool v2.96 and this loader worked a treat on both boards so far.

These are not perfect, and probably need fixes, but I like them.

Packages I added:

• libglx-mesa0, libgl1-mesa-dri
• mesa-utils, mesa-utils-extra
• vlc, glmark2-x11
• net-tools, screen, vim, neofetch, chromium

💾 Flashing Guide

For SD Card Images (-SD.img.bz2)

🐧 Linux / macOS

# Extract the image
bunzip2 Luckfox_Lyra_MicroSD_241230.img.bz2

# Flash to SD card (replace /dev/sdX with your device)
sudo dd if=Luckfox_Lyra_MicroSD_241230.img of=/dev/sdX bs=4M status=progress

# Sync to ensure all data is written
sync

Find your SD card device:

# Linux
lsblk

# macOS
diskutil list

🪟 Windows

1. Download Balena Etcher
2. Select your downloaded .img.bz2 file (Etcher handles decompression automatically)
3. Select your SD card
4. Click "Flash!"

🎯 Easy Method (All Platforms)

Use Balena Etcher - it's cross-platform and handles compression automatically:

1. Download Balena Etcher
2. Select image file
3. Select SD card
4. Flash!

For eMMC Flash Images (-eMMC.tar.bz2)

eMMC images require special tools:

• RkDevTool (Windows) - See Tools section
• upgrade_tool (Linux)

Expanding Root Partition (Optional)

After flashing, you may want to expand the root partition to use your full SD card space.

Using the Python Script

# Download the expansion script
wget https://raw.githubusercontent.com/platima/SBC-Images/main/Luckfox/Lyra/Tools/Luckfox_Lyra_expand_partition.py

# Make it executable
chmod +x Luckfox_Lyra_expand_partition.py

# Run as root (replace mmcblk0 with your device)
sudo ./Luckfox_Lyra_expand_partition.py /dev/mmcblk0

# Update kernel partition table
sudo partx -u /dev/mmcblk0

# Expand the filesystem
sudo resize2fs /dev/mmcblk0p3

💡 Device names:

• On the board itself: usually /dev/mmcblk0
• On PC with card reader: usually /dev/sdX

Using the SD Image Creation Script

Alternatively, use the Luckfox_make_SD_image.sh script to create SD card images with expanded partitions (macOS and Linux).

⚠️ Safety Checks

Before running any disk operations:

1. ✅ Verify your device path using lsblk
2. ✅ Ensure you have a backup of important data
3. ✅ Make sure you're expanding the correct partition (usually partition 3)
4. ⚠️ Using the wrong device path can result in data loss!
