Cannot detect COM port when downloading firmware

[Pinot]

Hello, I am a student who has been assigned by my teacher to study about AI-G. I have just started learning about the software. In the Linux SDK Getting Started section, I have completed the Setting Host Environment (Windows) and Image Build Guide parts.

At the Firmware Downloader step, I have downloaded the VCP Driver, set up Ethernet, checked that my computer has WMIC, connected everything as shown in Figure 4.1, powered on the board while pressing the FWDN switch.

However, I cannot see any COM port connection as shown in Figure 4.2. Has anyone encountered the same issue as me? I would really appreciate your help in resolving this problem. Thank you very much.

안녕하세요, 저는 선생님께 AI-G에 대해 조사하라는 과제를 받은 학생입니다. 현재 소프트웨어 부분을 처음으로 공부하고 있습니다. Linux SDK Getting Started에서 *Setting Host Environment (Windows)*와 Image Build Guide 부분을 완료했습니다.

Firmware Downloader 단계에서 VCP 드라이버를 다운로드하고, 이더넷을 설정했으며, PC에 WMIC가 있는지 확인했습니다. 또한 Figure 4.1과 같이 연결하고 FWDN 스위치를 누른 상태에서 전원을 인가했습니다.

하지만 Figure 4.2에서처럼 COM 포트 연결이 나타나지 않습니다. 저와 같은 문제를 겪으신 분이 계신가요? 이 문제를 해결하는 데 도움을 주시면 감사하겠습니다. 감사합니다.

Hello
It seems that the VTC driver was not installed correctly. We recommend first uninstalling the currently installed VTC driver and then reinstalling it with the VTC driver for the WIN10 version.
Thank you.

The COM port detection issue has been resolved. I replaced the USB Type-C cable and switched to using the Linux operating system. However, the current issue is that the board does not respond during the flashing process (stuck at “Waiting for SYNC Response”).

This issue occurs when the network settings are not configured correctly.
Please check if the Ethernet connection between the AI-G and the Host PC is correctly set to 192.168.0.8
Thank you.

[Pinot]

Sorry for the inconvenience. I have reconfigured the network settings as instructed, but the issue still persists.

[TOPST-manager-cy]

It seems that the issue can be resolved by setting the value of the gateway to 192.168.0.1.
Thank you.
