Leica Gnss equipment, known for its precision and reliability, requires specific care during firmware updates. While industrial SD cards function well for general data logging and file transfer, using Leica SD cards for firmware updates is crucial for optimal performance. Recent experiences highlight the importance of this seemingly minor detail.
A Leica GR30 receiver refused a firmware upgrade from a Lexar 128GB SD card used for static log storage. While the card flawlessly handled data storage, it failed in the firmware update process. Switching to a Leica SD card immediately resolved the issue, enabling a successful firmware upgrade.
Similarly, a Leica TS16 total station, typically updated via USB flash drives, encountered unusual behavior after a recent firmware update. The instrument wouldn’t shut down correctly. After extensive troubleshooting, reinstalling the firmware using a Leica SD card rectified the problem.
A Leica GS15 receiver, initially updated with an industrial SD card used for static data logging, also experienced unexpected behavior, failing to remain shut down. Reinstalling the firmware with a Leica SD card resolved the issue. This contrasts with other GS18/GS15 receivers using Leica SD cards without incident.
While a definitive technical explanation remains elusive, these experiences strongly suggest that utilizing Leica SD cards for firmware updates is essential for consistent and reliable performance. Going forward, using exclusively Leica SD cards for all firmware updates on Leica GNSS equipment is recommended, ensuring optimal functionality and mitigating potential issues. Using the correct SD card for firmware updates ensures the long-term health and accuracy of your valuable Leica GNSS equipment.
