Image Files
Summary
This page is the downloads hub for common images and resources referenced by LeMaker documentation. It also covers the small set of checks that prevent most “mystery” boot issues: verifying integrity, flashing to the correct device, and using reliable storage.
Who this is for
Anyone downloading OS images, firmware, or tooling and flashing them to microSD/eMMC for a first boot.
What you’ll do
- Choose a safe download method and avoid partial/corrupt files
- Verify checksums when provided
- Flash correctly and confirm the write completed
- Know what to check first when a board won’t boot
Download index
Primary download host:
mirror.lemaker.org
When multiple builds exist, prefer the most recently published image that matches your board model and storage type.
Requirements
- Storage: use a reputable microSD card; many intermittent failures are media-related.
- Reader: use a reliable card reader; flaky readers produce subtle corruption.
- Host OS: any modern Linux/macOS/Windows host can flash images; pick tooling you trust.
Integrity guidance
- Prefer HTTPS downloads.
- Verify checksums when available.
- Keep the original compressed image (and checksum file) so you can re-flash quickly.
- If a download was interrupted, delete it and re-download rather than “trying anyway.”
Checksum examples
SHA-256 verification (Linux/macOS):
cd /path/to/downloads
sha256sum -c image.sha256
SHA-256 verification (Windows PowerShell):
Get-FileHash .\image.img.xz -Algorithm SHA256 | Format-List
Flash checklist
| Check | Why it matters |
|---|---|
| Confirm the target device | Avoid wiping the wrong disk; identify the SD/eMMC device name before writing. |
| Write with sync/fsync | Ensures data is flushed to the card before you remove it. |
| Safely eject | Prevents the OS from caching writes and leaving the card incomplete. |
Troubleshooting
Boots sometimes, fails sometimes
- Replace the SD card first.
- Swap to a stable power supply and a short cable.
- Re-download and re-verify checksums.
No boot at all
- Confirm the image matches the board model.
- Try a different card reader and re-flash.
- If available, use a serial console to confirm what the bootloader is doing.
