Firmware Release Notes

1. More stable IMU output

   High-rate IMU data output is now more stable. Even under heavy system load, timestamp anomalies and data jitter are significantly reduced.

2. More reliable map transmission

   Transferring a relocalization map no longer interrupts the device’s camera video stream or causes the transfer to terminate unexpectedly.

3. Improved power-loss recovery

   After an unexpected power-off, the device retains its previous configuration on reboot, and SLAM no longer fails to start due to a corrupted configuration file.

4. More stable USB connection

   After the host reboots or the USB is briefly disconnected, the device reconnects normally — no more garbled data, transfer hangs, or residual files blocking subsequent connections.

5. More reliable calibration data loading

   Fixed a rare issue where abnormal calibration data could cause the device to reboot unexpectedly.

Upgrade Notes

• The communication protocol between the device and the host SDK has been updated.
• Be sure to upgrade the device firmware and the host-side SDK / driver at the same time.
• A version mismatch between the device and the host can cause unstable connections and abnormal communication.

ROS Driver Release Notes

1. Add support for firmware 0.12.0.
2. Reduce the latency of cloud_slam.
3. Improve the stability of map acquisition in SLAM mode.
4. Fix the failure of loading maps over USB 2.0 on ARM platforms.

Upgrade Procedure

Note: Do not run the driver during the upgrade, and do not power off during the process. A USB 3.0 port is recommended; USB 2.0 also works, but disconnections may occur during the upgrade and require restarting the upgrade with Ctrl+C.

1. Download the firmware via the link above.
2. Extract the archive.
3. Run the upgrade script (the upgrade tool is available with two suffixes: amd64 for x86 platforms and aarch64 for ARM platforms — pick the one that matches your platform):

# Example for an x86 platform
./odin1_firmware_update_tool_0.4.8_amd64 odin1_firmware_update_0.12.0.tar.gz

Wait for the upgrade to complete; the device will reboot automatically.
