Question 1

How to Update the Firmware Version of Unex Products?

Accepted Answer

Unex devices support two main firmware upgrade methods: Remote Firmware Upgrade and Standard Firmware Upgrade. You may select the most suitable option depending on your requirements. 1. Remote Firmware Upgrade Remote upgrades are applicable when the device’s system file structure is relatively simple and no major BSP (Board Support Package) changes are involved. Upgrade Steps: Prepare the upgrade package, which must include the required configuration files (e.g., wlist.gz and wlist.sign). Run the following script to verify, package, and upload the upgrade files to the remote device:./unex-firmware-upgrade.sh Before uploading, the script will check the device status and confirm that the device is included in the whitelist. During the upgrade, all partitions except for the UBI area will be overwritten and updated. Important configuration files will be automatically backed up and restored. *or detailed instructions, please refer to the Remote Firmware Upgrading Method section of the Software Development Guide: 2. Standard Firmware Upgrade The standard upgrade method applies to SDK v2.2.X and above. This process must be performed in a Linux environment and is suitable when minor BSP changes are required. Prerequisites: Ensure the device is properly mounted in the Linux system. Install the following dependencies:sudo apt install dfu-util u-boot-tools mtd-utils If running Linux in a virtual environment, confirm that the device has been mounted correctly. Upgrade Steps: Navigate to the flasher directory. Execute the following command to start the firmware upgrade:sudo ./dfu_flasher-x86_64 -f /config-unex-image-full-rootfs-atk42xx-vtx352-nand.txt After execution, enable DFU mode and reboot the device. The upgrade process will start automatically. Example Output: Writing UBI2 (32243712 bytes) from 0x12000000 to 0x13EC0000 Flashing done% Final Step: For detailed instructions, please refer to the Standard Firmware Upgrading Method section of the Software Development Guide: /Unex-Software-Development-Guide-us/modules/Firmware_Upgrade/usage/firmware_upgrade.html#standard-firmware-upgrading-method

Question 2

If the command execution fails, you may retrieve the version information using the methods described below.

1. Method 1: Query via Command:

Run the following command to query the firmware version of your Unex device, including both BSP and PROTOCOL versions:

Replace <device-IP> with the IP address of your Unex device.

Example:

If the device IP is 192.168.1.3, run:

2. Expected Output:

Unique ID: XXXXXXXX XXXXXXXX XXXXXXXX XXXXXXXX XXXXXXXX XXXXXXXX XXXXXXXX XXXXXXXX

BSP: VTX35X_v2.0.0

PROTOCOL: US CV2X STD v2.0.0

GNSS: Rel:B031U, debug/RTCM disabled, GP+GL, No Fix PPS, PSTMKFCOV 10HZ

3. Method 2: Alternative Approach:

If the above command fails, you can log in to the device directly and review the update logs by executing:

Question 3

What Should I Do If I Have Not Received the Whitelist? How Can I Obtain and Import It?

Accepted Answer

Please refer to the “Upload Whitelist” section under V2Xcast SDK in the Unex Software Development Guide (SDG) for full details: Preparation Create a folder (you may choose any name). Place the required whitelist files (.gz and .sign format) into this folder. These files are typically provided by Unex and sent to your company’s contact person via email. The email subject line will usually include “White List Files.” Upload Command Use the following command to upload the whitelist to the Unex device: ./v2xcast_manager -m put -f

/cfg/wlist : Path to the folder containing the whitelist files. : IP address of your Unex device. Example If your whitelist files are stored in ./whitelist_folder and include whitelist-20250101.gz and whitelist-20250101.sign, and the device IP is 192.168.1.3, run: ./v2xcast_manager -m put -f ./whitelist_folder 192.168.1.3/cfg/wlist Result After successful execution, the system will display: Uploading and applying wlist successful This indicates the whitelist has been uploaded and applied successfully.

Question 4

Are There Any Restrictions or Considerations Regarding Power Supply for Unex Products?

Accepted Answer

Please refer to the “Power Consumption” section in the Quick Start Guide of the purchased product. This section provides detailed information about the device’s power consumption range, which is typically between 2W and 4W.

The actual consumption may vary depending on the usage scenario. Therefore, it is recommended to adjust the power supply configuration according to your specific application.

Question 5

How to Quickly Verify V2X Message Transmission?

Accepted Answer

To verify device operation, complete the following steps:

Step 1: Confirm Device Connection

Ensure your Unex device is properly connected to the target system (e.g., PC or virtual machine). This may involve physical connections (USB, Ethernet) or mounting in a virtual environment.

Use the correct network interface to communicate with the Unex device for stable data transfer.

Step 2: Check Device Status

Run a simple network test (e.g., ping) to confirm the device is reachable.

Use the following commands to check if the device appears in the network interface list:

ifconfig

# or

ip a

Step 3: Compile and Run the V2X Example

Navigate to the folder containing the US V2Xcast example program.

Compile the example using the appropriate build commands.

Ensure all required dependencies and SDK tools are installed and configured.

Run the compiled example with your device connected and ready.

Step 4: Test and Verify

Confirm the program executes successfully.

Verify that V2X messages are transmitted and received correctly between devices.
