Claim or contact us about this channel. Greetings everyone, I want to divide a 50 MHz clock frequency by 2,3,4,5,6,7,8. I am using a Block Diagram Schematics. Can I do this by using a Counter?? I have tried using the modulus but I don't get any output in the Simulation. What can I do please?? Your help means a lot to me, Thanks! Transmit beamforming optional Thanks. But I found that pressing the Key 0 was not resetting.

Here is a correction: Code:. If yes! I simply cannot figure this out from any of the Altera documentation. I am using Quartus Prime Thank you. Best regards, Sanjay. Greetings everyone, I want to design an 8x1 Multiplexing system.

Starting with a frequency of 50 MHz as the first input to the multiplexer; I want to divide this frequency by 2,3, What can I do to accomplish this task???? I suppose the coding is also good, but a little more difficult. So please help me I don't know what to do with my project. Can I use 4 PLLs and give each one a different frequency???

Thanks for your help. Greetings all, I have designed a simple multiplexing system in Quartus II. I want so see the waveforms. My question is which one to use: Quartus Simulator or Modelsim??? And is Simulation considered the same as displaying??? Because I want to see exactly what I did, but I think simulation is controlled by the user.

Though I know its not officially supported on Ubuntu but I made some small changes to the PCIe driver files and was able to install all the components successfully. Running the tool as root does not have any effect. Could this be happening due to the tool's incompatibility with the Ubuntu Operating System or might I be missing something like compile time flags? Good day. I am trying to get acquainted with DE1-SoC. What i want to get is headless ubuntu with ability to program fpga.

Also for convenience purposes i'd like to use fpga-independent kernel not to change MSEL setup for "boot" and "runtime". In this thread, i'd like to ask for help with kernel compilation. Unfortunately, i have little experience with kernel. Dear all, I am designing a video system, and the rest of the basics are done video-in through Video for Linux 2 works as well as the processing itself.

BTW I had to move to kernel 4. The problem is: I have tried to use the fpga2sdram access port 1 in either bit or bit modes. I believe I am configuring the Frame Reader registers correctly. However, it seems that the Frame Reader is not streamed-in with any data.

I also have my framebuffer part which should not be the problem. In addition, I have configured the following Code:. Hello I have a c design that request packets from a qsys component. The packets pass through a sgdma and are returned on DDR memory The sgdma create an interrupt when finish to pass each packets When the optimization level is turned on , the interrupt dont arrive Can anybody help on this? The design behaves in a strange way. I cannot make them work.

The lock signal is low. I also use Signal tap. BUT the second one does not work. The first two plls work and their output clocks are generated successfully and their lock signals are raised. I tried different scenarios for the reset for the PLLs. I used a block that checks the lock signal. If the lock signal is low, it resets the PLL for few milliseconds and then de-asserts the reset signal and wait for ms and then again.

That block works with the input clk of the corresponding PLL. What would be the problem? The communication between boards is done using SPI interface. Both boards have JTAG. Thank you! I created a basic hello world template.

My hardware is the MAX 10 development kit. Everything works including printf. The problem is that when I power off the board and then back on everything works but the printf does not print to console. I have to program the FPGA again for the printf to work again.

I tried to reset through the jtag and also from a button, doesn't solve it. What am I missing? Thanks, Eyar. So which server or pc can i choose to mount DE4? The project has to access SD Card and it works well so far. But my problem is that, whenever I compile and try load the project into board, it gives error about "linux booting.. And I had to unplug the card for proper project loading. This is annoying, I don't want to remove sdcard from the slot each time I need to recompile and load the project.

How to disable sdcard linux boot option at power up? What is the clock frequency that ARM instructions are executed? If I toggle one of the GPIO pin by accessing its address directly, what is the possible square wave frequency that I can get? No matter what I do, I can't flash the memory on this board.

I've created a. Any idea what I'm doing wrong here? Thanks, Steve. Does Any body has seen this error. Below is the build log. Hi, I try to improve our SDCard reading performance. And this is after enabling cache, mmu and use high speed setting for MMC interface.
