  1. Hi, does the WLAN Pmod work out-of-the-box with Petalinux on Zybo? Best, Rainer
  2. @Notarobot. Probably yes, but as I Have not try this, I do not know what obstacles there are. On the other hand, OpenSSL is still part of the Petalinux distribution and it has configuration items in the roofs configuration file. But I wonder why there is no menu item visible for OpenSSL when I start the configurator by Petalinux-config -c rootfs
  3. Hi jpeyron, I think you misunderstood me. In this document are the libs stated which are necessary for the Petalinux toolchain. The Toolchain needs Openssl too (I have no clue why) What I want is to use the OpenSSL application and its associated crypto libraries on the Zybo. BR, Rainer
  4. Hi, I want to use OpenSSL on Petalinux 2016.4 . Maybe I am blind, but I cannot see it in the root_fs config menu. On the other hand, the package is there and it also listed in the rootfs_config text file. How can I activate it ? Best, Rainer
  5. After hours of debugging and reconfiguration and nearly killing my Ubuntu Linux system, I finally spotted the problem: When doing a virgin clean creation with petalinux-create --template zynq and a petalinux-config the following fields in "Yocto Settings " are automatically filled by the petalinux toolchain: Enable Network sstate feeds (NEW) = TRUE Network sstate feeds URL ---> │http://petalinux.xilinx.com/sswreleases/rel-v2016.4/arm/sstate-cache Unfortunately, the mentioned URL no longer exists and this is presumably the root cause of my error. By setting
  6. Hi, I am using Petalinux 2016.4 on Ubuntu 16.04. When I use Petalinux-build I get a list of errors, all similar to the following excerpt: ERROR: u-boot-xlnx-v2016.07-xilinx+gitAUTOINC+0b94ce5ed4-r0 do_package_write_rpm_setscene: Error executing a python function in exec_python_func() autogenerated: The stack trace of python calls that resulted in this exception/failure was: File: 'exec_python_func() autogenerated', lineno: 2, function: <module> 0001: *** 0002:do_package_write_rpm_setscene(d) 0003: File: '/opt/Xilinx/petalinux/2016.4/components/yocto/source/arm/
  7. Hi, I want to connect the Zybo as a SPI slave to a Raspberry Pi. Vivado offers an AXI Quad SPI core but it seems to me kind of overkill for that purpose. So, my first question is what would you recommend for a simple SPI slave: using this Vivado IP Building a custom IP with any freely available SPI slave core. Let's say, I use the Vivado Quad SPI core as a slave device. Then, I am correct that I only have to connect the following ports? sck_i io0_i as MOSI io1_0 as MISO io1_t to 0 Especially, I do not need the ss signal? Third, do you kno
  8. Update: The USB device gets not enumerated by Windows. As far as I now, even if the drivers are wrong or not present, the device should always occur in the Windows Device Manager. If this is not the case, I suppose that some very basic USB functionality dos not work. I think the USB device is defect and I have to replace the board.
  9. @[email protected]: ad 1. Power light is on. In addition to that, I also tried with an external power supply. ad 2. I use - please don't laugh - the cable from my Playstation 4 controller. In order to check that this cable is a full USB cable and not only a power supply, I connected the playstation controller with this cable to the USB port of my windows machine and observed the device manager. He recognized the new USB device. I assume that this proves that the USB cable is ok. ad 3. I plugged my old Digilent Spartan 3A board on this USB port and watched the windows device manager. The USB
  10. Hi, thank you for the quick answer. yes I tried both, but nothing worked. What me also puzzles is the fact that I cannot see any reaction on the Windows device manager when I plug/unplug the USB cable. In my opinion, by plugging the USB cable one should always see a new device appearing in the device manager. As this does not happen, I assume that my FTDI chip has a problem. I heard some rumours that new Windows FTDI drivers could destroy chips by overwriting some vital EEprom settings. I am not sure that this has happened. But is there a way to check if the FTDI ch
  11. Hi, I have a recently buyed a Zybo board and wanted to use it with Vivado 15.1 on Windows 10 I installed the cable drivers but the USB cable did not appear in the Windows device manager. Only the Jungo Windriver is there. It seems as would the FTDI chip be invisible for Windows. So, I assumed it is either defect or misconfigured. Therefore I tried to use the FTDI tools like FT_Prog to check the FTDI chip on the USB port. But still no luck. This tool doesn't work. It complains that FTD2XX.dll is missing. This DLL will not be installed by the Xilinix cable driver fo
