Hello,

To establish a serial connection between your Verdin development board and a Windows PC using the USB Type-C port, please follow these steps:

1. Verify Driver Installation: Ensure that the FTDI driver is correctly installed. The presence of ftd2xx.dll in C:\Windows\System32 is a good sign. However, double-check that the driver is properly associated with the USB device by:

   • Opening Device Manager on your Windows PC.
   • Expanding the ‘Universal Serial Bus controllers’ section.
   • Looking for any devices with a yellow exclamation mark, which indicates a driver issue.

2. Check USB Connection: Confirm that the USB Type-C cable is functioning correctly. Try using a different cable or port on your PC to rule out hardware issues.

3. Device Recognition: If the device is not recognized at all, it might be due to a power issue or a faulty connection. Ensure the board is powered on and the connection is secure.

4. Alternative Connection Methods: If the USB Type-C port continues to be unrecognized, consider using another method to establish a serial connection:

   • Use a different USB port on the development board if available.
   • Try connecting via Ethernet and using SSH if the board is network-enabled.

5. Terminal Emulator Setup: Since your PuTTY connection is working, ensure that the correct COM port is selected in PuTTY. If the device is recognized, it should appear as a COM port in Device Manager.

6. Reinstall Drivers: As a last resort, uninstall the FTDI drivers and reinstall them. Sometimes, a fresh installation can resolve recognition issues.

By following these steps, you should be able to troubleshoot and establish a serial connection between your Verdin development board and your Windows PC.

USB gadget not working (Verdin)

Hi, As the title says: we are having some problems with our USB on a custom developed carrier board for the Verdin. While trying to figure out this behavior we have reproduced the issue on the Verdin Development Board (V1.0B) as well. So the problem is that USB devices are not recognized when they are inserted after the Verdin has booted. To reproduce this issue on the development board we have disabled the USB hub by removing the jumpers SODIMM_185 and SODIMM_187. We have connected a USB hub …

Please try another USB-C cable. Many such cables these days are missing data lines or are of poor quality.

Please note that on the Verdin side, serial ports are available as regular tty devices (not ttyUSB).
