Get Your Xilinx FPGA/Programmable SoC Questions Answered here

rscasny
rscasny over 6 years ago

In the past year or so, the element14 community has been offering quite a few programs, contests, and initatives around Xilinx's FPGA and heterogeneous SoC, ZYNQ. We have hosted webinars, run roadtests, and offered a training program last year called Path to Programmable.

 

I see element14 member interest in Xilinx product knowledge on the rise. I plan on offering more Xilinx-related projects and roadtests in the coming months. (Stay tuned to Path to Programmable 2 with the Ultra96v2) Given all this activity, I thought it would be a great idea to bring in a Xilinx product expert for some well needed Q&A time. So let me introduce you to Adam Taylor ( adamtaylorcengfiet ).

 

I believe Adam has been an element14 member for several years. He is the Director of ADIUVO Engineering. He is a Chartered Engineer and Fellow of the Institute of Engineering and Technology. He is well known for his Microzed Chronicles. He writes the Exploring the Programmable World for element14. Adam has been instrumental in developing element14's FPGA/Programmable SoC Essentials.

 

Adam also is an expert in the PYNQ framework: Python for ZYNQ productivity. So, if you are asoftware developer who wants to explore the Programmable world, I'd encourage you to ask Adam your top questions.

 

So, if you have any questions revolving around FPGAs, programmable SoCs, a project in progress, perhaps even a question about Vivado, please click REPLY and asked them here.

 

Sincerely,

 

Randall Scasny

    Awesome! It's great that adamtaylorcengfiet is a resource on element14 for Programmable SoC questions. I'm sure I will have many as I finish my Digilent Zybo Z7 RoadTest. I do find Adam's Microzed Chronicles…

    For what it's worth, there is an Integrating Arm Cortex-M soft CPU IP into FPGAs virtual workshop that features Adam Taylor as an instructor and uses the Digilent Arty S7-50T to be held August 14th, 2019…

    Hi Adam (adamtaylorcengfiet ),

     

    I am one of the trainees for the Path II Programmable training program. I am working on the PetaLinux Lab 1. When I configured the Kernel using petalinux-config tool, the configuration went fine. However, when exited from the configuration tool, it showed three lines of error messages (highlighted below). After trying to run petalinux-build tool, it gave two lines of error messages (highlighted below). Can you tell me why it caused the error and how to solve it? Thanks.

     

    $petalinux-config --get-hw-description=../

    I checked the log files. The first problem I noticed is that my default Python version is 3.x not 2.x required by PetaLinux tools. I fixed the problem but still failed the build. Here's the latest content of build.log:

     

    [INFO] building project

    SDK environment now set up; additionally you may now run devtool to perform development tasks.

    Run devtool --help for further details.

    You had no conf/local.conf file. This configuration file has therefore been

    created for you with some default values. You may wish to edit it to, for

    example, select a different MACHINE (target hardware). See conf/local.conf

    for more information as common configuration options are commented.

     

    You had no conf/bblayers.conf file. This configuration file has therefore been

    created for you with some default values. To add additional metadata layers

    into your configuration please add entries to conf/bblayers.conf.

     

    The Yocto Project has extensive documentation about OE including a reference

    manual which can be found at:

        http://yoctoproject.org/documentation

    Found answer myself: https://forums.xilinx.com/t5/Embedded-Linux/petalinux-build-fails-in-VirtualBox-shared-folder/td-p/875986

    Basically, creating PetaLinux project in VM shared folder doesn't work. I have to use VM local folder.
