UART on ZedBoard

Hi all - first post :)

Please help if you can - I connected my Zedboard to my Windows 10 (64bit) PC for the first time today. The driver automatically installed the Digilent USB to Serial converter, which appears in the device manager. However, it installs no virtual COM port. I have tried uninstalling the driver found by Windows Update, disconnecting from my network, and installing the driver from Cypress (http://www.cypress.com/documentation/software-and-drivers/microsoft-certified-usb-uart-driver) which did not fix the problem. I also noticed that the chip on the board near the USB OTG port is an FTDI FT232, so I subsequently also installed that, but again, to no avail.

Could you please advise?

I don't have a Windows 10 PC to duplicate the issue but you may find some useful information in this post:

Let us know if you find a resolution. If anyone else has successfully installed the Cypress UART drivers on Win 10 please let us know.

Hi Gary,

Thanks for the response - I did try the steps in that forum, but unfortunately to no avail :( The Cypress UART driver directory in C:Program Files (x86)CypressCypress USB-Serial DriverDriverBinaryCDC_Driverbin has no sub-folder for Windows 10, and Device Manager will not allow me to install the driver for Windows 7 or 8.

Just to be certain, are you sure you are plugging into the USB-UART port? ZedBoard has 3 microUSB ports. If plugging in automatically installed the Digilent drivers, then that tells me you are plugged into the microUSB on the top of the board between the barrel jack and the audio jacks labeled PROG.

What happens if you plug into the microUSB on the left side of the board nearest the ON/OFF switch labeled UART?

I have also submitted a case to Cypress checking on Windows 10 compatibility.

Preliminary driver update from Cypress, including Windows 10. This link is only good for 1 week from today. Cypress will be posting this themselves soon, so I'm told.

Note -- I have not tried this myself!

Hi Bryan,

Thank you very much for this - your two posts solved the problem. I was indeed plugged into the wrong USB port on the board, and changing it, combined with installing the driver you posted, did the trick!

That is good news! I also got some additional information from Cypress.

These are the official drivers that will be released. Currently we are making an installer for this so that the customer doesn't have to manually install them. So we are taking time. But the drivers are being pushed through Windows update already. So the drivers are public through Windows Update.

Hi,

I've been struggling with this for 2 days now. Im still not getting it working. Could someone please just post a short sequence of installation instructions?

Thank you,
Bob.

Hello Bob,

To make sure we understand the problem, you are trying to use the Cypress USB UART on the ZedBoard with Windows 10?

If so I would first attempt to just connect the ZedBoard USB UART port (J14 on the ZedBoard) directly to a USB port on your Windows machine and see if the driver is installed automatically (if Cypress has pushed the updated driver already). Don't be impatient as this can take a little while to complete on occasion. I don't have a Windows 10 PC to test this on.

If this does not work then I would download the driver update listed above, while it is still active, and replace the Cypress USB UART driver on your Windows 10 PC.

I had the problem with the both avnet cypress driver and cypress official driver. Both updates only install the zedboard as usb-art adapter but the COM port does not appear under Ports (COM & LPT) in the device manager. The work around that I follow that works is by following the steps in:

http://zedboard.org/content/uart-driver-does-not-work-new-pc

However, once you're connected to the internet, the driver for the usb will update itself and the usb serial port will disappear again under the Ports (COM & LPT). The workaround for this step is just rollback the driver. The com would appear again.

I have traced the problem for this update in Event Viewer and it points to:

Driver Management concluded the process to install driver cypressusbandbus.inf_amd64_b9411dae2ee00e22cypressusbandbus.inf for Device Instance ID USBVID_04B4&PID_00080410A3D82426 with the following status: 0x0.

This is the addendum to the error message I posted.
