If you tell me that you used it on an older version of Ubuntu, then Ill start thinking that there is a driver incompatibility with the newest kernel.I am running the Xilinx SDK to program my zedboard on Kubuntu 16.04.I can complete the blinking led tutorial flawlessly but the helloworld one is pretty tough.Ive implemented a minimalist design in vivado with a zynq 7 PS with its uart1 interface enabled (default setting).
Ubuntu Read Serial Port Driver Incompatibility WithIve then exported the bitstream to the SDK and created the helloworld example project. When it comes to program the FPGA, or the PS, everything seems to work fine but nothing appears in the terminal. Do you have any idea about where the problem comes from I also specify that I have usb 3.0 ports available and I cant use windows or mac os. Some of this information may be useful to you and I posted my workarounds on this thread here. I also took a look at Svens tutorial and found nothing about the UART configuration except the dialog group thing (which Ive already done). ![]() But I wonder if using the Mac layer before the VB virtualization can help to get it working. As an additional test, I took my 5kg gaming laptop to give the UART port a try on windows and it worked. But I am not really happy with it as I cant stand working on windows and I dont really want a 5kg terminal when I work on my zedboard. To sum up, I can connect to the UART port as a ttyACM0 node is created as soon as I plug the board. I can use various terminals to watch at the ttyACM0 port (with or without sudo). Then, nothing reach the terminal, which stays desperately empty. I actually found nobody who managed to use the UART port on a native Ubuntu, which worries me a little bit. Ubuntu Read Serial Port Serial Communications RelatedSo here come a few questions: - Do you think that reinstalling the JTAG driver in the same way than Sven would change anything for the UART - Ive done this to check if I can do something serial communications related on my system and I can. ![]() Ive also read this article which seems to say that a UART-USB connection is supposed to lead to a ttyUSB node whereas I only have a ttyACM node. Do you have any idea if it can be a clue Regards, Gabriel PS: If you wonder why is my English approximate, then I confess, Im French;P And I am also far from being a Linux expert (I am not a neophyte either) so I apologize if I say stupid things sometimes. I would venture to guess that your time is worth something valuable, so at some point an alternative solution to the current path will be more appealing. In my previous post, I was able to get the USB-UART to work fine on a native CentOS install (not virtualized at all). Also, I have used ZedBoard USB-UART just fine under Ubuntu 10.04 LTS when we wrote Appendix III of the ZedBoard Getting Started Guide. This has the added benefit of the connection being completely secured if you are worried about people snooping on your work over the network. Ive tried to connect to Kubuntu on my other computer and with both USB3 and 2 this time with the very same result: Nothing. As it almost exactly the same OS, it just proves that my main Kubuntu behaves normally.
