Build a project with the Arty S7 - Line Follower Robot (Part 2) - Setting up Vivado 2019.2 and Demo program

rahulkhanna

A quick update on the hardware issue. I tried powering the board and it didn't power up. It turns out the hardware had a short-circuit in production. Short in R220 and R217 had resulted in the failure of a 3.3V supply to the board which was removed. Even though I removed the short, it had already fried the power regulator. After replacing the high-performance multi-output LDO ADP5052, the board is ready to be powered.

Setting up Vivado 2019.2

Xilinx Unified installer allows users to install multiple Xilinx tools using a single installer. Users can install Vivado Design Environment, Vitis, Lab Edition, Hardware Server, On-premise install for cloud deployment, Bootgen, and Documentation Navigator using a single installer.

  1. Go to the Xilinx Downloads Website.
  2. Click an installation file to download it. Xilinx Unified Installer 2019.2: Windows Self Extracting Web Installer
  3. Select a product to install

It took me more than 6 hours to install Vivado 2019.2 

Demo program 

  • Firstly, we will be adding the board files to the directory.

  • Copy and paste the board files to /Vivado/2019.2/data/boards/board_files/ 

  • Now create a new project on the Vivado 2019.2 IDE and name the project. 

  • Select ARTY S7-50 under the board's tab and click the Next button to create the project. 

  • Add the constraint and source files to the project
  • Run Synthesis, Implementation, and Generate Bitstreams as shown. 
  • Select the local device and click on the program to upload the bitstream. Once uploaded, click on the prog reset button to run the program. 

Now, the Demo program is active. The LED combinations are made using SW1, SW2, SW3, and SW4. The device is ready to be programmed. 

We will be interfacing with the sensors and will be implementing a motor control program in the next blog.

    Thanks for the tips.
    It will be interesting to see another approach to the line follower. I'm sure yours works better, the PmodColor sensor is not a good idea for a line follower with one sensor. It performs a value filtering itself and the response is very slow. It cost me a lot of time to adjust the values of the PID controller.

    Identifying the issue was the critical part and it took me a few weeks to rectify the problem. Once you had found out the reason behind the short circuit, I suggest you use a high-temperature resistant masking tape to cover the surrounding components, and then remove the IC using the desoldering station. In this way, you can replace the required components without disturbing other components. By the way,  Great projects! The project which I'm working on is one of your projects. Let me see if I could bring up something different. 

  • I'm glad you were able to fix your board. My board also has the AD2384 regulator burned out, I couldn't locate why it melted, it's connecting it and starting to smell burnt, some short circuit somewhere.
    Has the repair been very difficult for you? I have hardly any experience desoldering such small components, I almost always end up destroying everything around it. Any advice from your experience?
