Jetson not loading ubuntu

[2505shan]

I identified the COM port associated with my Jetson device as COM6 in the Device Manager. However, when attempting to connect PuTTY to this COM port using the recommended settings (115200 8N1), the connection is unsuccessful.

Steps Taken:

1. Checked COM Port: Confirmed that the COM port associated with the Jetson device is COM6.
2. PuTTY Configuration: Configured PuTTY with the correct COM port (COM6), speed (115200), and other recommended settings.
3. Connection Attempt: Attempted to connect PuTTY to the Jetson device using the configured settings.
4. Observations: Despite following the steps meticulously, the connection to the Jetson device using PuTTY is not successful.

Is there a specific troubleshooting step I may have overlooked, or are there alternative methods to verify the serial line connection?

Thanks for your response and support.
