  1. Linux Hardware Driver for Arty-Z7

    I wish to access own ip-cores while i'am using Linux on the Arty-Z7 board. What is the general workflow to write a Linux-Hardware-Driver for the Arty-Plattform? Do you have any examples? Thank you...
  2. I recently purchased the chipkit UC32 from digilent to do a labview project but when I connect it to my Windows 10 laptop, it says “USB device not recognized”. In the device manager of my computer I see the error in the port under Universal Serial Bus Controllers and it has the yellow triangle error symbol next to “Unknown USB Device (Device Descriptor Request Failed)” I have tried many things to try and get it working but have failed. Please help
  3. At the description of the Pmod Step it says that it can drive both motors simultaneously. I want to know if it can drive them with different number of steps on each motor. So the Pmod STEP will be like an 2 in 1 driver or it can only drive identical the motors.
  4. Error in PmodSD.tcl file ?

    Hi, Inside file https://github.com/Digilent/vivado-library/blob/master/ip/Pmods/PmodSD_v1_0/drivers/PmodSD_v1_0/data/PmodSD.tcl shouldn't 'PmodWIFI' not be replaced by 'PmodSD' ? wkr Eddy
  5. Hi, I installed also petalinux 2015.4 (beside 2017.2) in the scope of solveing my problem, but without success. I want to integrate a kernel driver into petalinux rootfs to comunicate with an PL block which has 2 interfaces (lite interface and full interface - both memory mapped). When i created the module into petalinux, i let the code as it was generated..just i overwrote the ".compatible" section with the comptabile section from pl.dtsi(in my case <xlnx,accHW-1.0>) At insmod it doesn't output both conversions (phisical to virtual adresses). It shows just the conversion for the lite interface (0x43c0 0000 to 0xe09a 0000). root@Avnet-Digilent-ZedBoard-2015_4:/lib/modules/4.0.0-xilinx/extra# insmod driv er-mihai.ko [ 95.237408] <1>Hello module world.

Or where can i see them ?
  6. Installed Waveform 2015 software as instructed and installed the driver also. Couldn't get the Analog Discovery 2 to get recognized until after I rebooted the system. But it is only recognized if I plug it directly into my machine. If I use a hub, It doesn't work. The problem is I have several Arduino boards that use FTDI chips also plugged into my system through hubs and they were all working just fine before I installed your provided driver. Now they also only function if they are plugged directly into the laptop. I can't operate that way, how do I uninstall the driver or keep your driver from breaking my other devices on the system. Even one of my hard drives that is connected through an Anker 3.0 HUB no longer connects unless directly connected. Another hard drive is still working through the hub. After restarting the mac several times, I got things to work by unplugging the actual powered hub. Unplugging from the computer wasn't enough, I needed to unplug power from the hub before things started to work again. We still need some sort of uninstall instructions. macOS Sierra 10.12.3 MacBook pro Mid 2012 16 Gig ram.
  7. Hello, I am trying to connect to the DAC using petalinux, but I cannot get it to work. When petalinux is booted i get "axi-i2s: probe of 43c00000.axi_i2s_adi failed with error -2", I have tried to find information about this, but so far i haven't found anything. So, what I have done: I have synthesized the template design and imported the said design into Petalinux. I have configured ALSA as this: The device tree for the axi-i2s is as follows: amba_pl: amba_pl { axi_i2s_adi_0: axi_i2s_adi@43c00000 { compatible = "adi,axi-i2s-1.00.a"; reg = <0x43c00000 0x10000>; clocks = <&clkc 15 &clkc 16>; clock-names = "axi", "i2s"; dmas = <&dmac_s 0 &dmac_s 1>; dma-names = "tx", "rx"; xlnx,bclk-pol = <0x0>; xlnx,dma-type = <0x1>; xlnx,has-rx = <0x1>; xlnx,has-tx = <0x1>; xlnx,lrclk-pol = <0x0>; xlnx,num-ch = <0x1>; xlnx,slot-width = <0x18>; }; }; I am deeply grateful for any help, or any examples showing a working DAC interface. Best regards /Jaxc
  8. Digilent myrio Motor adapter

    Digilent driver providing only 0.6A at max for single motor. But I require current upto 1.5A how to overcome this problem. Also there is no braking in motor driver. Is there any option in driver to electrically brake the motor. Thanks in Advance
  9. Hello, I have been struggling for a while now trying to get sound on the ZyBo board. I built images with the OpenEmbedded and Yocto projects where I added the following layers: https://github.com/emcongiu/meta-zybo https://github.com/Xilinx/meta-xilinx I enabled so many recipes that I couldn't remember exactly which ones. As a test, I also tried the Linaro distro provided in this tutorial: https://reference.digilentinc.com/zybo:zybo:zybotguide But still no sound card detected. I really need to work with the audio on this board, how can I enable it ? Thanks in advance
