  1. Hi All, I am newbie to zynq board, eagerly started to learn. I have digilent HDMI FMC card it supports 8,10,12 bits color depth. I am trying with pixel width 10-bits with xilinx zynq zc702 board. previously we used Avnet HDMI FMC card it supports only 8-bit pixel width.Now we are in need to move with 10 and 12-bits pixel width. 1. What are the things needed to use digilent fmc card with zync zc702 board. 2.Where i can get drivers (c-code libs) for digilent fmc card. 3.While its operating in 10-bit mode should i connect it with 10-bit color depth output of laptop? 4.Can i use Avnet fmc card drivers for this digilent fmc card too ? (in this case i need to change EDID content w.r.t digilent fmc card) 5. Kindly help me regarding this, It would be a great help to me..!!! I Tried as Mentioned Below : 1.I am not having the digilent fmc card drivers to use and compile it with my application C-code so i used with some changes of Avnet fmc card driver C-codes. Also chnaged the EDID content w.r.t digilent fmc card ref Document. 2.I used lenova G580 lap to connect HDMI o/p from laptop to FMC card using HDMI cable.digilent fmc card mode is pixel width is 10-bit but while looking at Graphics card properties of Lap shows that the color depth is 32-bit output, I am sure whther it will support the 10-bit mode digilent fmc card. 3.Any how, While running it I am facing the error message which is given below, Error: ADV7611 has NOT locked on incoming video, aborting ! Thanks, Ramesh
  2. Hey guys, We are currently two students trying to use the Audio chip(SSM2603) on the Zybo board. Currently we are unsure on how to generate a proper block design(IP) that would allow us to generate a bitstream and take in input from the mic line and send out that audio output. We were also wondering what VHDL code was used for the audio codec package. We have been trying to use the axi_i2s_adi block but are unsure on how to use it due to the lack of documentation. Kindly help us by sharing projects or ideas! Best Regards!
  3. Hello, I currently use a JTAG-HS2 cable with my Zynq development board. What would be the advantage or disadvantage of switching to a JTAG-HS3 cable with (exclusive) regard to using it with Zynq devices (Through Vivado 2014.4 and SDK)? I found this comparison table : http://www.digilentinc.com/choosing.cfm I think the big difference towards Zynq is the PS_SRST support, however it's not clear to me what exactly this is? I can use the Zynq now with my HS-2 cable, put breakpoints, ... so I wonder what this extra feature might bring to the table. I guess the 'no support for 2-wire JTAG' and SPI' is not an issue with Zynq devices (?) best regards
  4. Hi, I am currently using Zybo board. I have followed the " Embedded Linux® Hands-on Tutorial for the ZYBO™ " tutorial. My question is how does the Zynq system works? Is it similar to Microblaze soft processor or is it just FPGA? I have done the same work in the tutorial using Microblaze processor and XIlinx ISE. I find in the specs that Zynq hosts 2 ARM cortex processors, I want to know when we run above the above tutorial are we using any soft processor or if we are using the ARM Cortex processor? My point is if any soft processor is involved we can eliminate it and use the ARM processors so that we can achieve more speed. Thank you in advance.
  5. I was wondering if anyone could guide me in the right direction for troubleshooting a USB peripheral connection with the Zybo board running embedded Digilent Linux. My boot is as follows, which shows the USB root device (not OTG - the title is a mistake) appears to be loaded properly but no USB devices show: U-Boot 2014.01-00005-gc29bed9 (Feb 01 2015 - 22:39:09) I2C: ready Memory: ECC disabled DRAM: 512 MiB MMC: zynq_sdhci: 0 SF: Detected S25FL128S_64K with page size 256 Bytes, erase size 64 KiB, total 16 MiB *** Warning - bad CRC, using default environment In: serial Out: serial Err: serial Net: Gem.e000b000 Hit any key to stop autoboot: 0 Device: zynq_sdhci Manufacturer ID: 27 OEM: 5048 Name: SD04G Tran Speed: 50000000 Rd Block Len: 512 SD version 3.0 High Capacity: Yes Capacity: 3.7 GiB Bus Width: 4-bit reading uEnv.txt ** Unable to read file uEnv.txt ** Copying Linux from SD to RAM... reading uImage 3819360 bytes read in 340 ms (10.7 MiB/s) reading devicetree.dtb 7374 bytes read in 18 ms (399.4 KiB/s) reading uramdisk.image.gz 3694172 bytes read in 329 ms (10.7 MiB/s) ## Booting kernel from Legacy Image at 03000000 ...

    Zedboard Done Light?

    I unpacked my Zedboard and followed the "Getting Started Instructions" but the blue DONE LED(LD12) doesn't light. I suspect this means the Zynq isn't booting. Any suggestions?
