Sometimes, power issues happen during the firmware update procedure or when parameters are being written into the device’s flash memory. These power issues cause the corruption of the flash memory. The possible effects of the corruption flash are that the device cannot be turned on, there is gibberish in the serial number, the baud rate cannot be determined, the device does not start data output, etc. Inertial Labs updated the tool to restore the device’s parameters and firmware. The article describes in detail how to use the tool. Please contact the Inertial Labs support team at support@inertiallabs.com, and we’ll prepare and provide the recovery pack for your device.
Please download the recovery tool using the link provided by the Inertial Labs support team and unpack the archive. The firmware and parameters can be restored using a GUI or CLI.
Restoring the firmware and parameters using GUI
To restore the firmware and parameters using GUI, connect the main COM1 port of the device to your PC using the RS232-to-USB converter and run the Device_fw_and_prm_restoring-gui.exe from \Recovery_ FXXXXXX\Device_fw_and_prm_restoring\ folder. In the opened window, select the port number assigned to the RS232-to-USB converter by your OS and click the “Restore” button, as shown in Figure 1.
The standard Windows “Open” window will appear, in which it is necessary to set the path to the file with the firmware and parameters. This file has *rconf extension and contains the firmware version and device serial number. If the folder contains two files, please select the file according to your application: land or aerial. Press the “Open” button to start the restoring.
It is necessary to do the power cycle following the tool prompts. The restoring starts after the power cycle.
The message “Restoring was successfully completed” should appear after the procedure is finished. Please do the power cycle of the device and try to work with the device as usual, using the GUI software, for example.
Restoring the firmware and parameters using CLI
To restore the firmware and parameters using CLI, connect the main COM1 port of the device to your PC using the RS232-to-USB converter, press the right mouse button, and select Open in Terminal in the \Recovery_ FXXXXXX\Device_fw_and_prm_restoring\ folder. In the opened command line window, print and run the command as on example:
.\Device_fw_and_prm_restoring-console.exe –rc A2IMU_3_5_5_4_20240809+F1710224.rconf
Please note that your *conf file will have another name with your device’s serial number and the firmware that has been released.
Select the port number assigned to the RS232-to-USB converter by your OS and do the power cycle following the tool prompts. The restoring starts after the power cycle and pressing the Enter button.
The message “Firmware and parameters restoring completed successfully ” should appear after the procedure is finished. Please do the power cycle of the device and try to work with the device as usual.
