  1. P.S.: have to correct myself. Appearently you can use the central interconnect for that.
  2. UART are connected to pins that cannot be accessed by PL. You could use a USB-TTL chip. As a side note, I am missing the reference to the FTDI on the zybo_sch.pdf... or at least a reference to connector J11. Took me a while to find the uart pins o.O
  3. I think there is a confusion. I am not talking about IO buffer (i.e., "physical ports") here. A port list is a list of inputs and outputs of your module as you declared here: Vivado needs a top module. The top module contains a port list that Vivado is going to wire to physical pins. Your top module is pwm that's why Vivado does what it did. Instead, use a top module that instantiates axi and pwm like so: top_module ( output pwm_out, inout DDR_... ... inout FIXED_IO... ... ); Vivado tries automatically to figure out which is your top module. If you have
  4. You are correct, you need to declare your module entity, instantiate the module, instantiate the axi interface and map the signals to your port lists. I think these instructions here show you exactly what you are trying to do. It uses 4 PWM signals instead of one but is very easy to adjust.
  5. did you use Vivado/Tools/create and package new IP as a starting point? It generates the axi wrapper for you. Instantiate your module and connect registers to axi. Again, your error log let's me assume something is wrong with your module.
  6. the problem is in your source file. If you want to synthesize your design you have to fix: A LUT 'cnt2_i_2' is driving clock pin of 11 registers. Number of unplaced terminals (64) is greater than number of available sites (50) otherwise it will only work in simulation.
  7. I searched for inactive driver in the Windows device manager and found out that there appear 2 x USB Serial Converter A and 2 x USB Serial Converter B. I deleted all of them and powered the board. Now both boards work.
  8. Hello, just plugged in my new Zybo Z7 471-015 but cannot connect to serial port. It works on the Zybo. PROG UART is connected to USB PC BSP stdin, stdout is set to ps7_uart_1 I have no other application open that is accessing the serial ports to make sure I dis- and reconnected the Zybo Z7, still doesn't appear on the port list Zybo Z7 appears as USB Serial Converter A and B in the device mngr restarted PC tried another USB port replaced USB cable, both are data cables JP6 is set to USB JP5 is set to JTAG drivers had been insta
  9. The pixel clock is directly derived from the video input, TMDS CLK. One character is 10 bit. Since it is DDR your pixel clock is 5 times lower than the serial, i.e., bit clock.
  10. hello, My new board just arrived yesterday I received my Zynq Development Voucher with instructions: log in to xilinx confirm your purchase and license entitlement placed into my account, code may only be used once generate FLEX license for product. Must be redeemed within one year of purchase I want to wait for a future release of Vivado before I use the license. So according to instructions, I need to perform steps 1 + 2, and wait until that release before generating the license. Is this correct? Just want to be sure before messing something up
  11. https://www.xilinx.com/support/documentation-navigation/boards-and-kits/spartan-3/hw-spar3an-sk-uni-g.html UG334 has a 3AN Ref. D, not sure if that is the right board: https://www.gta.ufrj.br/ensino/EEL480/spartan3/ug334.pdf btw @[email protected], your link does not work for me...
  12. hello, is it possible to delete my account on this site? I found out I have 2 of them
  13. did you successfully program the board before? is the power led (red) on? are the jumpers on the board correctly placed? is the device recognized by the tool? the operating system is not a great deal in your case
  14. It shows error messages to help you identify the problem. Without them it is hard to find out what's wrong, not just for you but also for others trying to help...
  15. I am upgrading the HDMI SDSoC platform from the latest version, which is for 2015.4. I forked Digilent github from here: https://github.com/Digilent/SDSoC-platforms/tree/master/2015.4/zybo_hdmi_in
  16. can you be more specific? what error messages do you get? with SDK?
  17. I could observe that the SDSoC project does indeed have the file '720p_edid.txt' in the release folder. It gets deleted somehow during compilation. I copied it back in place before compilation finished and was able to generate the sd_card files that way.
  18. @RaulRB : you'r right, I moved the workspace to another location. I created the platform again this time with the include folder (arm-xilinx-eabi). It did not work, however: when I create a new project with the basic example of the platform I still need to copy the header files manually to the project: D:\SDSoC\ddd\Release>C:\Xilinx\SDx\2017.1\llvm-clang\win64\llvm\bin\clang.exe -I../src -Wall -fmessage-length=0 -MMD -MP -D __SDSCC__ -target arm-none-eabi -mcpu=cortex-a9 -mfpu=vfpv3 -O0 -g -I C:/Xilinx/SDx/2017.1/target/aarch32-none/include -I C:/Xilinx/SDx/2017.1/Vivado_HLS/incl
  19. SDSoC 2017.1 complains about an outdated file structure. I successfully created a new platform as in UG1146. Appearantly I missed one step since the header files had not been included. I added the custom platform and created a new project with the arraycopy sample. After manually adding xgpio.h it completes building. but when I enable create bitfile, create sd card it takes forever to compile and ends with errors. I'll try and create a new fsbl...
  20. hello, I am updating the platform for Vivado 2017.1 Do I need to create a new fsbl or can I use the existing files? Also, do I need to declare some sdsoc::pfm_iodev to run the provided bare metal projects?
