# Firmware Update For PCIe devices, it is recommended to update to the latest firmware for stable driver execution and optimal performance. It is available on both **Linux/Ubuntu** and **Windows** systems. ```{attention} - Please complete driver installation before proceeding with [firmware update](installing_driver.md). - Please check the compatible runtime and firmware versions [here](compatibility.md) - The update process is performed identically on both Linux and Windows. ``` ## Table of Contents - [Download firmware tool](#download-firmware-tool) - [Update firmware](#update-to-latest-firmware) - [Option 1: Update with GUI tool](#option-1-update-with-gui-tool) - [Option 2: Update with Console tool](#option-2-update-with-console-tool) - [Check firmware](#check-firmware-version) ## Download firmware tool Download and install the latest tool suitable for your current OS from the [Download Site](https://dl.mobilint.com/releases?series-id=9&product=ARIES). * Windows : mobilint_ctrl_v?_windows.zip * Linux(debian package) : aries_flash_firmware_?.deb, mobilint_ctrl_?.deb ## Update to latest firmware Depending on the execution environment, update methods are provided in both the GUI and the Console environment. You must close all AI applications before proceeding with the update. ### Option 1: Update with GUI tool Run the `mobilint_ctrl` program and click the `firmware` tab. ![Firmware Tab](/res/image/mobilint_ctrl_firmware_0.png "Firmware Tab") Click the `Check Firmware Update...` button to check the currently installed firmware. ![Check current firmware](/res/image/mobilint_ctrl_firmware_1.png "Check current firmware") Click the `Update Firmware...` button to proceed with the latest firmware update. ![Update firmware](/res/image/mobilint_ctrl_firmware_2.png "Update firmware") ```{attention} - This process takes about 7~10 seconds. - Never turn off the host PC during the update. - An internet connection is required because the latest firmware is downloaded online. ``` If the latest firmware is already installed, it will be displayed as follows. ![Already the latest firmware](/res/image/mobilint_ctrl_firmware_3.png "Already the latest firmware") The installed firmware will be applied after a reboot. ### Option 2: Update with Console tool You can update the firmware to the latest version using the `aries_flash_firmware update` command. An internet connection is required at this moment. If executed successfully, the update process will be displayed as shown below. ```bash > aries_flash_firmware update * PCIe Device Driver connection details. > Driver version : 1.8.2 (Revision 2) > PCIe card connection information. - Main-System(VID:0x209F,DID:0x0000), Sub-System(VID:0x0402,DID:0x1093), PCIe 4.0 - 8 Lanes Device type : Aries 2 (Firmware v1.2.5 rev#0) Product type : Commercial Board type : Low profile DRAM size : 16 GB *I: Current firmware. - Reading Board [==================================================] Done.
