I would like to adapt that code in such a way that I can send data to my ZedBoard from a terminal or some kind of program that implements serial communication.
On the other hand, sending data from the ZedBoard to my PC works properly, and I can see the messages coming from the board in different terminals. I have attached the source code that I can't get to understand and I think is giving me problems. My questions are preceded by a hash sign:. At the moment, every attempt has been unsuccessful.

The application sends data and expects to receive the same data through the device using the local loopback mode I would like to adapt that code in such a way that I can send data to my ZedBoard from a terminal or some kind of program that implements serial communication. By default it is disabled.
Thank you in advance Christian.

To be able to talk to an application, such as a PicoBlaze 8-bit processor application, your Linux machine must have the appropriate Silabs drivers. Ubuntu No installation of drivers is necessary. The only thing necessary is to check whether the Ubuntu machine can communicate over USB with the attached Xilinx development board.
The last line, can be on your system another line, shows that the Silabs device on the Xilinx development board has been detected and that the drivers on the PC are running.
Again, on your machine the numbers might be different. The important line for us is that telling where the driver connects to a TTY port, in this case it is line three "cpx converter now attached to ttyUSB2". Setup the communication with a terminal window so that commands can be exchanged with the application running in the FPGA on the development board.Xilinx DLC9LP: Программатор FPGA
I'm using here GTKterm as an example but any other debug terminal program can be used. If GTKterm is not installed on you machine and you want to use it:. From eLinux. Jump to: navigationsearch. Communicate with Xilinx development boards via USB. Turn the board on.

GTKterm Setup the communication with a terminal window so that commands can be exchanged with the application running in the FPGA on the development board.
Now GTKterm is installed and available for use. Start it from the open terminal window as root. Click 'Configuration' and select 'Port', as shown in the figure below. Category : Zynq. Navigation menu Personal tools Log in Request account.
There is a issue in ZCU board. It will work. Board has issue. You can proceed to file a devsys RMA case if your board is under 90 days warranty. View solution in original post.
If yes proceed for next step. Are you using the same cable in ZCU board? If no, please try, so that we can isolate the issue it is not due to cable. ZCU board revision?

Hi Deepak 1.As a first test, I send a x array from the computer and I receive it on the Zedboard. The issue that I am having is that even thought I am not sending anything from the PCI still get into the interruption from what it seems to be a loopback from the Rx to Tx when I send back information from the Zedboard to the PC. I would like to clear it as i do not want to receive what I send over Rx.
View solution in original post. I have tested out by commenting the line where I send data from the FPGA to the PC and if I do not send anything from the PC to the Zedboard, then the interruption never happens which is the expected behavior. This proves that I get an interruption when there is something on the UART, whether it is sending or receiving and I only want to have an interruption when I receive something.

The driver installation program finishes "correctly" however under Device Manager I can never see the Cypress device when zedboard is poweredup. The post mentioned does not solve my problem. I only see the same COM1 port that has been there before. If I try to update the drivers for such COM1 port and select Win7 drivers from Cypress installed folders then it does change the type of the port to USB serial port but still does not work.
I never see any amber light flashing and no output on the console terminal. I tried this same procedure with Win10 drivers from same Cypress folders and got the same results. Between each attempt I restarted windows after uninstalling previous driver and restarted again after installing new driver. Really need help for my specific problem please.

I suggest you to try installing Vivado Now I am basically idle I am using ISE I followed the procedures in the link and restart the computer. Thanks in advance. I had tried all the suggested method before and it did not worked until i erase windrvr6.
I've been chasing this problem for a while, and found none of the solutions worked for me. I finally found a solution for my similar problem. Although this specific device I am using has a Xilinx sticker on it, it is a cheap reproduction.

Note that this readme file refers to my complete solution which can be downloaded below. However, you can look at just the parts that talk about USB cable drivers if that's all you're interested in. The attached file will allow you to install Xilinx cable drivers in a windows XP or possibly a windows 7 OS.
It comes with the Xilinx cable drivers as well as a tool that will install the drivers into your windows OS. This VM can be installed in a windows 10 or other OS and can run fine from there. If you want to download my complete solution including windows XP VM, all drivers and FPGA programming tool already pre-installedyou can download it here.
Note that this download link is only for demonstration and testing purposes. I am providing my full solution download link for good karma, and because I believe in, and depend on, the open source community to solve crazy problems and simply get stuff done.
The complete solution download is about 2. I posted my solution yesterday: I got both programmers to work in two differents PC with Windows Did you try if my solution worked for you?
