Greetings
I'm trying to establish communication between Digilent FPGA board with Xilinx Zynq platform and matlab for my university project. As per matlab instruction, it is required to assign USB UART connection such as Silicon Labs CP210x USB to UART Bridge or Cypress Serial. However, I'm geting code 10 in windows (8.1, 10, 11) device manager. I tried different solutions suggested in the internet but they didn't work.
I appreciate your support to share with me what kind of computer specificaiton and windows version have been tested to have successful installation of Silicon Labs CP210x USB to UART Bridge or Cypress Serial. I have tried different computers and virtual machine but no result to install the drivers without errors

Hello Ali,
I had to install the driver recently to connect the ZCU102 board to a computer with no Vivado Installation (that often installs the driver already). I downloaded the driver here: https://www.silabs.com/developers/usb-to-uart-bridge-vcp-drivers?tab=downloads (CP210x Universal Windows Driver). After installation I had to go to the device manager to update the driver for the device(s). After that, the UART interface worked. I tested it with PuTTY (the com-Port can be found through the Device Manager as well). It looked then like this:

After opening the connection, I have access to the linux shell.
Best regards,
Tom

Can you try to update the driver again after installing? On page 3 of your PDF, the last image shows an exclamation mark. Right-click this device and say update driver, manual path, and enter the path to the installation or unzipped files. If this still fails and you also find no one else who can successfully get it running, you device could be broken.
Best regards,
Tom
